* network: define new API virNetworkUpdateLaine Stump2012-09-181-0/+1
| | | | | | This patch adds a new public API virNetworkUpdate that will permit updating an existing network configuration without requiring that the network be destroyed/restarted for the changes to take effect.
* blockjob: add virDomainBlockCommitEric Blake2012-09-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A block commit moves data in the opposite direction of block pull. Block pull reduces the chain length by dropping backing files after data has been pulled into the top overlay, and is always safe; block commit reduces the chain length by dropping overlays after data has been committed into the backing file, and any files that depended on base but not on top are invalidated at any point where they have unallocated data that is now pointing to changed contents in base. Both directions are useful, however: a qcow2 layer that is more than 50% allocated will typically be faster with a pull operation, while a qcow2 layer with less than 50% allocation will be faster as a commit operation. Committing across multiple layers can be more efficient than repeatedly committing one layer at a time, but requires extra support from the hypervisor. This API matches Jeff Cody's proposed qemu command 'block-commit': https://lists.gnu.org/archive/html/qemu-devel/2012-09/msg02226.html Jeff's command is still in the works for qemu 1.3, and may gain further enhancements, such as the ability to control on-error handling (it will be comparable to the error handling Paolo is adding to 'drive-mirror', so a similar solution will be needed when I finally propose virDomainBlockCopy with more functionality than the basics supported by virDomainBlockRebase). However, even without qemu support, this API will be useful for _offline_ block commits, by wrapping qemu-img calls and turning them into a block job, so this API is worth committing now. For some examples of how this will be implemented, all starting with the chain: base <- snap1 <- snap2 <- active + These are equivalent: virDomainBlockCommit(dom, disk, NULL, NULL, 0, 0) virDomainBlockCommit(dom, disk, NULL, "active", 0, 0) virDomainBlockCommit(dom, disk, "base", NULL, 0, 0) virDomainBlockCommit(dom, disk, "base", "active", 0, 0) but cannot be implemented for online qemu with round 1 of Jeff's patches; and for offline images, it would require three back-to-back qemu-img invocations unless qemu-img is patched to allow more efficient multi-layer commits; the end result would be 'base' as the active disk with contents from all three other files, where 'snap1' and 'snap2' are invalid right away, and 'active' is invalid once any further changes to 'base' are made. + These are equivalent: virDomainBlockCommit(dom, disk, "snap2", NULL, 0, 0) virDomainBlockCommit(dom, disk, NULL, NULL, 0, _SHALLOW) they cannot be implemented for online qemu, but for offline, it is a matter of 'qemu-img commit active', so that 'snap2' is now the active disk with contents formerly in 'active'. + Similarly: virDomainBlockCommit(dom, disk, "snap2", NULL, 0, _DELETE) for an offline domain will merge 'active' into 'snap2', then delete 'active' to avoid leaving a potentially invalid file around. + This version: virDomainBlockCommit(dom, disk, NULL, "snap2", 0, _SHALLOW) can be implemented online with 'block-commit' passing a base of snap1 and a top of snap2; and can be implemented offline by 'qemu-img commit snap2' followed by 'qemu-img rebase -u -b snap1 active' * include/libvirt/libvirt.h.in (virDomainBlockCommit): New API. * src/libvirt.c (virDomainBlockCommit): Implement it. * src/libvirt_public.syms (LIBVIRT_0.10.2): Export it. * src/driver.h (virDrvDomainBlockCommit): New driver callback. * docs/apibuild.py (CParser.parseSignature): Add exception.

* Add virDomainGetHostnameGuido Günther2012-07-201-0/+5
| | | | | | to query a guests's hostname. Containers like LXC and OpenVZ allow to set a hostname different from the hosts name and QEMU's guest agent could provide similar functionality.
* list: add virDomainListAllSnapshots APIEric Blake2012-06-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | There was an inherent race between virDomainSnapshotNum() and virDomainSnapshotListNames(), where an additional snapshot could be created in the meantime, or where a snapshot could be deleted before converting the name back to a virDomainSnapshotPtr. It was also an awkward name: the function operates on domains, not domain snapshots. virDomainSnapshotListChildrenNames() suffered from the same inherent race, although its naming was nicer. This patch makes things nicer by grabbing a snapshot list atomically, in the format most useful to the user. * include/libvirt/libvirt.h.in (virDomainListAllSnapshots) (virDomainSnapshotListAllChildren): New declarations. * src/libvirt.c (virDomainSnapshotListNames) (virDomainSnapshotListChildrenNames): Add cross-references.

* lib: Add public api to enable atomic listing of guestPeter Krempa2012-06-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new public api that lists domains. The new approach is different from those used before. There are key points to this: 1) The list is acquired atomically and contains both active and inactive domains (guests). This eliminates the need to call two different list APIs, where the state might change in between the calls. 2) The returned list consists of virDomainPtrs instead of names or ID's that have to be converted to virDomainPtrs anyways using separate calls for each one of them. This is more convenient and saves hypervisor calls. 3) The returned list is auto-allocated. This saves a lot of hassle for the users. 4) Built in support for filtering. The API call supports various filtering flags that modify the output list according to user needs. Available filter groups: Domain status: VIR_CONNECT_LIST_DOMAINS_ACTIVE, VIR_CONNECT_LIST_DOMAINS_INACTIVE Domain persistence: VIR_CONNECT_LIST_DOMAINS_PERSISTENT, VIR_CONNECT_LIST_DOMAINS_TRANSIENT Domain state: VIR_CONNECT_LIST_DOMAINS_RUNNING, VIR_CONNECT_LIST_DOMAINS_PAUSED, VIR_CONNECT_LIST_DOMAINS_SHUTOFF, VIR_CONNECT_LIST_DOMAINS_OTHER Existence of managed save image: VIR_CONNECT_LIST_DOMAINS_MANAGEDSAVE, VIR_CONNECT_LIST_DOMAINS_NO_MANAGEDSAVE Auto-start option: VIR_CONNECT_LIST_DOMAINS_AUTOSTART, VIR_CONNECT_LIST_DOMAINS_NO_AUTOSTART Existence of snapshot: VIR_CONNECT_LIST_DOMAINS_HAS_SNAPSHOT, VIR_CONNECT_LIST_DOMAINS_NO_SNAPSHOT 5) The python binding returns a list of domain objects that is very neat to work with. The only problem with this approach is no support from code generators so both RPC code and python bindings had to be written manually. *include/libvirt/libvirt.h.in: - add API prototype - clean up whitespace mistakes nearby *python/generator.py: - inhibit generation of the bindings for the new api *src/driver.h: - add driver prototype - clean up some whitespace mistakes nearby *src/libvirt.c: - add public implementation *src/libvirt_public.syms: - export the new symbol
* snapshot: new query APIsEric Blake2012-06-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, starting from just a virDomainSnapshotPtr, and wanting to know if it is the current snapshot for its respective domain, you have to use virDomainSnapshotGetDomain(), then virDomainSnapshotCurrent(), then compare the two names returned by virDomainSnapshotGetName(). It is a bit easier if we can directly query this information from the snapshot itself. Right now, it is possible to filter a snapshot listing based on whether snapshots have metadata that would prevent domain deletion, but the only way to learn if an individual snapshot has metadata is to see if that snapshot appears in the list returned by a listing. Additionally, I hope to expand the qemu driver in a future patch to use qemu-img to reconstruct snapshot XML corresponding to internal qcow2 snapshot names not otherwise tracked by libvirt (in part, so that libvirt can guarantee that new snapshots are not created with a name that would silently corrupt the existing portion of the qcow2 file); if I ever get that in, then it would no longer be an all-or-none decision on whether snapshots have metadata, and becomes all the more important to be able to directly determine that information from a particular snapshot. Other query functions (such as virDomainIsActive) do not have a flags argument, but since virDomainHasCurrentSnapshot takes a flags argument, I figured it was safer to provide a flags argument here as well. * include/libvirt/libvirt.h.in (virDomainSnapshotIsCurrent) (virDomainSnapshotHasMetadata): New declarations. * src/libvirt.c (virDomainSnapshotIsCurrent) (virDomainSnapshotHasMetadata): New functions. * src/libvirt_public.syms (LIBVIRT_0.9.13): Export them. * src/driver.h (virDrvDomainSnapshotIsCurrent) (virDrvDomainSnapshotHasMetadata): New driver callbacks.
* snapshot: add virDomainSnapshotRef APIEric Blake2012-06-081-0/+5
| | | | | | | | | | | | | virDomainSnapshotPtr has a refcount member, but no one was able to use it. Furthermore, all of our other vir*Ptr objects have a *Ref method to match their *Free method. Thankfully, this is client-side only, so we can use this new function regardless of how old the server side is! (I have future patches to virsh that want to use it.) * include/libvirt/libvirt.h.in (virDomainSnapshotRef): Declare. * src/libvirt.c (virDomainSnapshotRef): Implement it. * src/libvirt_public.syms (LIBVIRT_0.9.13): Export it.
* Introduce virDomainPMWakeup APIMichal Privoznik2012-02-271-0/+5
| | | | | This API allows a domain which previously called virDomainPMSuspendForDuration() to be woken up.
* block rebase: add new API virDomainBlockRebaseEric Blake2012-02-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qemu is adding the ability to do a partial rebase. That is, given: base <- intermediate <- current virDomainBlockPull will produce: current but qemu now has the ability to leave base in the chain, to produce: base <- current Note that current qemu can only do a forward merge, and only with the current image as the destination, which is fully described by this API without flags. But in the future, it may be possible to enhance this API for additional scenarios by using flags: Merging the current image back into a previous image (that is, undoing a live snapshot), could be done by passing base as the destination and flags with a bit requesting a backward merge. Merging any other part of the image chain, whether forwards (the backing image contents are pulled into the newer file) or backwards (the deltas recorded in the newer file are merged back into the backing file), could also be done by passing a new flag that says that base should be treated as an XML snippet rather than an absolute path name, where the XML could then supply the additional instructions of which part of the image chain is being merged into any other part. * include/libvirt/libvirt.h.in (virDomainBlockRebase): New declaration. * src/libvirt.c (virDomainBlockRebase): Implement it. * src/libvirt_public.syms (LIBVIRT_0.9.10): Export it. * src/driver.h (virDrvDomainBlockRebase): New driver callback. * src/rpc/gendispatch.pl (long_legacy): Add exemption. * docs/apibuild.py (long_legacy_functions): Likewise.
* API: Add api to set and get domain metadataPeter Krempa2012-02-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds API to modify domain metadata for running and stopped domains. The api supports changing description, title as well as the newly added <metadata> element. The API has support for storing data in the metadata element using xml namespaces. * include/libvirt/libvirt.h.in * src/libvirt_public.syms - add function headers - add enum to select metadata to operate on - export functions * src/libvirt.c - add public api implementation * src/driver.h - add driver support * src/remote/remote_driver.c * src/remote/remote_protocol.x - wire up the remote protocol * include/libvirt/virterror.h * src/util/virterror.c - add a new error message note that metadata for domain are missing
* virDomainGetDiskErrors public APIJiri Denemark2012-02-011-0/+1
| | | | | | We already provide ways to detect when a domain has been paused as a result of I/O error, but there was no way of getting the exact error or even the device that experienced it. This new API may be used for both.
* Add new public API virDomainGetCPUStats()KAMEZAWA Hiroyuki2012-01-281-1/+2
| | | | | | | | | | | | | | | | add new API virDomainGetCPUStats() for getting cpu accounting information per real cpus which is used by a domain. The API is designed to allow future extensions for additional statistics. based on ideas by Lai Jiangshan and Eric Blake. * src/libvirt_public.syms: add API for LIBVIRT_0.9.10 * src/libvirt.c: define virDomainGetCPUStats() * include/libvirt/libvirt.h.in: add virDomainGetCPUStats() header * src/driver.h: add driver API * python/generator.py: add python API (as not implemented) Signed-off-by: Eric Blake <eblake@redhat.com>
* Introduce virDomainPMSuspendForDuration APIMichal Privoznik2012-01-281-0/+1
| | | | | | | | This API allows a domain to be put into one of S# ACPI states. Currently, S3 and S4 are supported. These states are shared with virNodeSuspendForDuration. However, for now we don't support any duration other than zero. The same apply for flags.
* resize: add virStorageVolResize() APIZeeshan Ali (Khattak)2012-01-271-0/+1
| | | | | | | | | | Add a new function to allow changing of capacity of storage volumes. Plan out several flags, even if not all of them will be implemented up front. Expose the new command via 'virsh vol-resize'. Signed-off-by: Eric Blake <eblake@redhat.com>
* Remove tabs from libvirt_public.syms & enforce itDaniel P. Berrange2012-01-261-228/+228
| | | | | * src/libvirt_public.syms: Death to tabs * cfg.mk: Check .syms files for tabs
* storage: Support different wiping algorithmsMichal Privoznik2012-01-261-0/+2
| | | | | | | Currently, we support only filling a volume with zeroes on wiping. However, it is not enough as data might still be readable by experienced and equipped attacker. Many technical papers have been written, therefore we should support other wiping algorithms.
* Add new virDomainShutdownFlags APIDaniel P. Berrange2012-01-241-0/+4
| | | | | | | | | | | | | | | | | | | Add a new API virDomainShutdownFlags and define: VIR_DOMAIN_SHUTDOWN_DEFAULT = 0, VIR_DOMAIN_SHUTDOWN_ACPI_POWER_BTN = (1 << 0), VIR_DOMAIN_SHUTDOWN_GUEST_AGENT = (1 << 1), Also define some flags for the reboot API VIR_DOMAIN_REBOOT_DEFAULT = 0, VIR_DOMAIN_REBOOT_ACPI_POWER_BTN = (1 << 0), VIR_DOMAIN_REBOOT_GUEST_AGENT = (1 << 1), Although these two APIs currently have the same flags, using separate enums allows them to expand separately in the future. Add stub impls of the new API for all existing drivers
* domiftune: clean up previous patchesEric Blake2012-01-021-2/+2
| | | | | | | | | | | | | | | | | Most severe here is a latent (but currently untriggered) memory leak if any hypervisor ever adds a string interface property; the remainder are mainly cosmetic. * include/libvirt/libvirt.h.in (VIR_DOMAIN_BANDWIDTH_*): Move macros closer to interface that uses them, and document type. * src/libvirt.c (virDomainSetInterfaceParameters) (virDomainGetInterfaceParameters): Formatting tweaks. * daemon/remote.c (remoteDispatchDomainGetInterfaceParameters): Avoid memory leak. * src/libvirt_public.syms (LIBVIRT_0.9.9): Sort lines. * src/libvirt_private.syms (domain_conf.h): Likewise. * src/qemu/qemu_driver.c (qemuDomainSetInterfaceParameters): Fix comments, break long lines.
* domiftune: Add API virDomain{S,G}etInterfaceParametersHu Tao2011-12-291-0/+2

* block_resize: Define the new APIOsier Yang2011-11-291-0/+1
| | | | | | | | The new API is named as "virDomainBlockResize", intending to add support for qemu monitor command "block_resize" (both HMP and QMP). Similar with APIs like "virDomainSetMemoryFlags", the units for argument "size" is kilobytes.
* Add a public API to invoke suspend/resume on the hostSrivatsa S. Bhat2011-11-291-0/+1
| | | | | | Implement the public definitions for the new API virNodeSuspendForDuration() which will be subsequently used to do a timed suspend on the host.
* Introduce virConnectIsAlive APIJiri Denemark2011-11-241-0/+1
| | | | | | | This API can be used to check if the socket associated with virConnectPtr is still open or it was closed (probably because keepalive protocol timed out). If there the connection is local (i.e., no socket is associated with the connection, it is trivially always alive.
* Introduce virConnectSetKeepAliveJiri Denemark2011-11-241-0/+5
| | | | | | | virConnectSetKeepAlive public API can be used by a client connecting to remote server to start using keepalive protocol. The API is handled directly by remote driver and not transmitted over the wire to the server.
* Introduce the virDomainOpenGraphics APIDaniel P. Berrange2011-10-281-0/+1
| | | | | | | | | | | | | | The virDomainOpenGraphics API allows a libvirt client to pass in a file descriptor for an open socket pair, and get it connected to the graphics display of the guest. This is limited to working with local libvirt hypervisors connected over a UNIX domain socket, since it will use UNIX FD passing * include/libvirt/libvirt.h.in: Define virDomainOpenGraphics * src/driver.h: Define driver for virDomainOpenGraphics * src/libvirt_public.syms, src/libvirt.c: Entry point for virDomainOpenGraphics * src/libvirt_internal.h: VIR_DRV_FEATURE_FD_PASSING

| | | | | | | | | | | | | | | | | | | | | | The previous API addition allowed traversal up the hierarchy; this one makes it easier to traverse down the hierarchy. In the python bindings, virDomainSnapshotNumChildren can be generated, but virDomainSnapshotListChildrenNames had to copy from the hand-written example of virDomainSnapshotListNames. * include/libvirt/libvirt.h.in (virDomainSnapshotNumChildren) (virDomainSnapshotListChildrenNames): New prototypes. (VIR_DOMAIN_SNAPSHOT_LIST_DESCENDANTS): New flag alias. * src/libvirt.c (virDomainSnapshotNumChildren) (virDomainSnapshotListChildrenNames): New functions. * src/libvirt_public.syms: Export them. * src/driver.h (virDrvDomainSnapshotNumChildren) (virDrvDomainSnapshotListChildrenNames): New callbacks. * python/generator.py (skip_impl, nameFixup): Update lists. * python/libvirt-override-api.xml: Likewise. * python/libvirt-override.c (libvirt_virDomainSnapshotListChildrenNames): New wrapper function.

* snapshot: new virDomainSnapshotGetParent APIEric Blake2011-09-281-0/+5
| | | | | | | | | | | | | | Although a client can already obtain a snapshot's parent by dumping and parsing the xml, then doing a snapshot lookup by name, it is more efficient to get the parent in one step, which in turn will make operations that must traverse a snapshot hierarchy easier to perform. * include/libvirt/libvirt.h.in (virDomainSnapshotGetParent): Declare. * src/libvirt.c (virDomainSnapshotGetParent): New function. * src/libvirt_public.syms: Export it. * src/driver.h (virDrvDomainSnapshotGetParent): New callback.
* snapshot: new APIs for inspecting snapshot objectEric Blake2011-09-081-1/+4
| | | | | | | | | | | | | | These functions access internals of the opaque object, and do not need any rpc counterpart. It could be argued that we should have provided these when snapshot objects were first introduced, since all the other vir*Ptr objects have at least a GetName accessor. * include/libvirt/libvirt.h.in (virDomainSnapshotGetName) (virDomainSnapshotGetDomain, virDomainSnapshotGetConnect): Declare. * src/libvirt.c (virDomainSnapshotGetName) (virDomainSnapshotGetDomain, virDomainSnapshotGetConnect): New functions. * src/libvirt_public.syms: Export them.

* save: new API to manipulate save file imagesEric Blake2011-07-211-0/+2
| | | | | | | | | | | | | | | | | | | | Modifying the xml on either save or restore only gets you so far - you have to remember to 'virsh dumpxml dom' just prior to the 'virsh save' in order to have an xml file worth modifying that won't be rejected due to abi breaks. To make this more powerful, we need a way to grab the xml embedded within a state file, and from there, it's not much harder to also support modifying a state file in-place. Also, virDomainGetXMLDesc didn't document its flags. * include/libvirt/libvirt.h.in (virDomainSaveImageGetXMLDesc) (virDomainSaveImageDefineXML): New prototypes. * src/libvirt.c (virDomainSaveImageGetXMLDesc) (virDomainSaveImageDefineXML): New API. * src/libvirt_public.syms: Export them. * src/driver.h (virDrvDomainSaveImageGetXMLDesc) (virDrvDomainSaveImgeDefineXML): New driver callbacks.
* destroy: Define new public API virDomainDestroyFlagsMichal Privoznik2011-07-211-0/+1
| | | | | | | | | | | | This introduces new API virDomainDestroyFlags to allow domain destroying with flags, as the existing API virDomainDestroy misses flags. The set of flags is defined in virDomainDestroyFlagsValues enum, which is currently commented, because it is empty. Calling this API with no flags set (@flags == 0) is equivalent calling virDomainDestroy.
* save: new public API to bypass file system cache on save/restoreEric Blake2011-07-211-0/+2
| | | | | | | | | | | | | | | | | | | In order to choose whether to use O_DIRECT when saving a domain image to a file, we need a new flag. But virDomainSave was implemented before our policy of all new APIs having a flag argument. Likewise for virDomainRestore when restoring from a file. The new flag name is chosen as CACHE_BYPASS so as not to preclude a future solution that uses posix_fadvise once the Linux kernel has a smarter implementation of that interface. * include/libvirt/libvirt.h.in (virDomainCreateFlags) (virDomainCoreDumpFlags): Add a flag. (virDomainSaveFlags, virDomainRestoreFlags): New prototypes. * src/libvirt.c (virDomainSaveFlags, virDomainRestoreFlags): New API. * src/libvirt_public.syms: Export them. * src/driver.h (virDrvDomainSaveFlags, virDrvDomainRestoreFlags): New driver callbacks.
* undefine: Define the new APIOsier Yang2011-07-201-0/+5
| | | | | | | | | | | | | | This introduces a new API virDomainUndefineFlags to control the domain undefine process, as the existing API virDomainUndefine doesn't support flags. Currently only flag VIR_DOMAIN_UNDEFINE_MANAGED_SAVE is supported. If the domain has a managed save image, including VIR_DOMAIN_UNDEFINE_MANAGED_SAVE in @flags will also remove that file, and omitting the flag will cause undefine process to fail. This patch also changes the behavior of virDomainUndefine, if the domain has a managed save image, the undefine will be refused.
* build: rename Vcpupin to VcpuPinEric Blake2011-06-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | We already have a public virDomainPinVcpu, which implies that Pin and Vcpu are treated as separate words. Unreleased commit e261987c introduced virDomainGetVcpupinInfo as the first public API that used Vcpupin, although we had prior internal uses of that spelling. For consistency, change the spelling to be two words everywhere, regardless of whether pin comes first or last. * daemon/remote.c: Treat vcpu and pin as separate words. * include/libvirt/libvirt.h.in: Likewise. * src/conf/domain_conf.c: Likewise. * src/conf/domain_conf.h: Likewise. * src/driver.h: Likewise. * src/libvirt.c: Likewise. * src/libvirt_private.syms: Likewise. * src/libvirt_public.syms: Likewise. * src/libxl/libxl_driver.c: Likewise. * src/qemu/qemu_driver.c: Likewise. * src/remote/remote_driver.c: Likewise. * src/xen/xend_internal.c: Likewise. * tools/virsh.c: Likewise. * src/remote/remote_protocol.x: Likewise. * src/remote_protocol-structs: Likewise.
