Management software wants to be able to allocate disk space on demand. To support this they need keep track of the space occupation of the block device. This information is reported by qemu as part of block stats. This patch extend the block information in the bulk stats with the allocation information. To keep the same behaviour a helper is extracted from qemuMonitorJSONGetBlockExtent in order to get per-device allocation information.

A long time ago in a galaxy far, far away it has been decided that libvirt will manage not only domains but host as well. And with my latest work on qemu driver supporting huge pages, we miss the cherry on top: an API to allocate huge pages on the run. Currently users are forced to log into the host and adjust the huge pages pool themselves. However, with this API the problem is gone - they can both size up and size down the pool.

We stupidly modeled block job bandwidth after migration bandwidth, which in turn was an 'unsigned long' and therefore subject to 32-bit vs. 64-bit interpretations. To work around the fact that 10-gigabit interfaces are possible but don't fit within 32 bits, the original interface took the number scaled as MiB/sec. But this scaling is rather coarse, and it might be nice to tune bandwidth finer than in megabyte chunks. Several of the block job calls that can set speed are fed through a common interface, so it was easier to adjust them all at once. Note that there is intentionally no flag for the new virDomainBlockCopy; there, since the API already uses a 64-bit type always, instead of a possible 32-bit type, and is brand new, it was easier to just avoid scaling issues. As with the previous patch that adjusted the query side (commit db33cc24), omitting the new flag preserves old behavior, and the documentation now mentions limits of what happens when a 32-bit machine is on either client or server side. * include/libvirt/libvirt.h.in (virDomainBlockJobSetSpeedFlags) (virDomainBlockPullFlags) (VIR_DOMAIN_BLOCK_REBASE_BANDWIDTH_BYTES) (VIR_DOMAIN_BLOCK_COMMIT_BANDWIDTH_BYTES): New enums. * src/libvirt.c (virDomainBlockJobSetSpeed, virDomainBlockPull) (virDomainBlockRebase, virDomainBlockCommit): Document them. * src/qemu/qemu_driver.c (qemuDomainBlockJobSetSpeed) (qemuDomainBlockPull, qemuDomainBlockRebase) (qemuDomainBlockCommit, qemuDomainBlockJobImpl): Support new flag.

Total time of a migration and total downtime transfered from a source to a destination host do not count with the transfer time to the destination host and with the time elapsed before guest CPUs are resumed. Thus, source libvirtd remembers when migration started and when guest CPUs were paused. Both timestamps are transferred to destination libvirtd which uses them to compute total migration time and total downtime. Obviously, this requires the time to be synchronized between the two hosts. The reported times are useless otherwise but they would be equally useless if we didn't do this recomputation so don't lose anything by doing it. Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

To date, anyone performing a block copy and pivot ends up with the destination being treated as <disk type='file'>. While this works for data access for a block device, it has at least one noticeable shortcoming: virDomainGetBlockInfo() reports allocation differently for block devices visited as files (the size of the device) than for block devices visited as <disk type='block'> (the maximum sector used, as reported by qemu); and this difference is significant when trying to manage qcow2 format on block devices that can be grown as needed. Of course, the more powerful virDomainBlockCopy() API can already express the ability to set the <disk> type. But a new API can't be backported, while a new flag to an existing API can; and it is also rather inconvenient to have to resort to the full power of generating XML when just adding a flag to the older call will do the trick. So this patch enhances blockcopy to let the user flag when the resulting XML after the copy must list the device as type='block'. * include/libvirt/libvirt.h.in (VIR_DOMAIN_BLOCK_REBASE_COPY_DEV): New flag. * src/libvirt.c (virDomainBlockRebase): Document it. * tools/virsh-domain.c (opts_block_copy, blockJobImpl): Add --blockdev option. * tools/virsh.pod (blockcopy): Document it. * src/qemu/qemu_driver.c (qemuDomainBlockRebase): Allow new flag. (qemuDomainBlockCopy): Remember the flag, and make sure it is only used on actual block devices. * tests/qemuxml2argvdata/qemuxml2argv-disk-mirror.xml: Test it.

While reviewing the new virDomainBlockCopy API, Peter Krempa pointed out that our existing design of using MiB/s for block job bandwidth is rather coarse, especially since qemu tracks it in bytes/s; so virDomainBlockCopy only accepts bytes/s. But once the new API is implemented for qemu, we will be in the situation where it is possible to set a value that cannot be accurately reflected back to the user, because the existing virDomainGetBlockJobInfo defaults to the coarser units. Fortunately, we have an escape hatch; and one that has already served us well in the past: we can use the flags argument to specify which scale to use (see virDomainBlockResize for prior art). This patch fixes the query side of the API; made easier by previous patches that split the query side out from the modification code. Later patches will address the virsh interface, as well retrofitting all other blockjob APIs to also accept a flag for toggling bandwidth units. * include/libvirt/libvirt.h.in (_virDomainBlockJobInfo) (VIR_DOMAIN_BLOCK_COPY_BANDWIDTH): Document sizing issues.

Let's fix this before we bake in a painful API. Since we know that we have exactly one non-negative fd on success, we might as well return the fd directly instead of forcing the user to pass in a pointer. Furthermore, I found some memory and fd leaks while reviewing the code - the idea is that on success, libvirtd will have handed two fds in two different directions: one to qemu, and one to the RPC client. * include/libvirt/libvirt.h.in (virDomainOpenGraphicsFD): Drop unneeded parameter. * src/driver.h (virDrvDomainOpenGraphicsFD): Likewise. * src/libvirt.c (virDomainOpenGraphicsFD): Adjust interface to return fd directly. * daemon/remote.c (remoteDispatchDomainOpenGraphicsFd): Adjust semantics. * src/qemu/qemu_driver.c (qemuDomainOpenGraphicsFD): Likewise, and plug fd leak. * src/remote/remote_driver.c (remoteDomainOpenGraphicsFD): Likewise, and plug memory and fd leak.

This commit (finally) adds the virDomainBlockCopy API, with the intent that it will provide more power to the existing 'virsh blockcopy' command. 'virsh blockcopy' was first added in Apr 2012 (v0.9.12), which corresponds to the upstream qemu 1.2 timeframe. It was done as a hack on top of the existing virDomainBlockRebase() API call, for two reasons: 1) it was targetting a feature that landed first in downstream RHEL qemu, but had not stabilized in upstream qemu at the time (and indeed, 'drive-mirror' only landed upstream in qemu 1.3 with slight differences to the first RHEL attempt, and later gained further parameters like granularity and buf-size that are also worth exposing), and 2) extending an existing API allowed it to be backported without worrying about bumping .so versions. A virDomainBlockCopy() API was proposed at that time [1], but we decided not to accept it into libvirt until after upstream qemu stabilized, and it ended up getting scrapped. Whether or not RHEL should have attempted adding a new feature without getting it upstream first is a debate that can be held another day; but enough time has now elapsed that we are ready to do the interface cleanly. [1] https://www.redhat.com/archives/libvir-list/2012-April/msg00768.html Delaying the creation of a clean API until now has also had a benefit: we've only recently learned of a few shortcomings in the original design: 1) it is unable to target a network destination (such as a gluster volume) because it hard-coded the assumption that the destination is a local file name. Because of all the refactoring we've done to add virStorageSourcePtr, we are in a better position to declare an API that parses XML describing a host storage source as the copy destination, which was not possible had we implemented virDomainBlockCopy as it had been originally envisioned (although a network target will have to wait until a later libvirt release compared to the API addition to actually be implemented). 2) the design of using MiB/sec as the bandwidth throttle is rather coarse; qemu is actually tuned to bytes/second, and libvirt is preventing access to that level of detail. A later patch will add flags to existing block job API that can request bytes/second instead of back-compat MiB/s, but as this is a new API, we can get it right to begin with. At least I had the foresight to create 'virsh blockcopy' as a separate command at the UI level (commit 1f06c007) rather than leaking the underlying API overload of virDomainBlockRebase onto shell users. A further note on the bandwidth option: virTypedParameters intentionally lacks unsigned long (since variable-width interaction between mixed 32- vs. 64-bit client/server setups is nasty), but we have to deal with the fact that we are interacting with existing older code that mistakenly chose unsigned long bandwidth at a point before we decided to prohibit it in all new API. The typed parameter is therefore unsigned long long, but the implementation (in a later patch) will have to do overflow detection on 32-bit platforms, as well as capping the value to match the LLONG_MAX>>20 cap of the existing MiB/s interfaces. * include/libvirt/libvirt.h.in (virDomainBlockCopy): New API. (virDomainBlockJobType, virConnectDomainEventBlockJobStatus): Update related documentation. * src/libvirt.c (virDomainBlockCopy): Implement it. * src/libvirt_public.syms (LIBVIRT_1.2.8): Export it. * src/driver.h (_virDriver): New driver callback.

The motivation for this API is that management layers that use libvirt usually poll for statistics using various split up APIs we currently provide. To get all the necessary stuff, the app needs to issue a lot of calls and aggregate the results. The APIs I'm introducing here: 1) Returns data in a format that we can expand in the future and is (pseudo) hierarchical. The data is returned as typed parameters where the fields are constructed as dot-separated strings containing names and other stuff in a list of typed params. 2) Stats for multiple (all) domains can be queried at once and are returned in one call. This will decrease the overhead necessary to issue multiple calls per domain multiplied by the count of domains. 3) Selectable (bit mask) fields in the returned format. This will allow to retrieve only specific stats according to the app's need. The stats groups will be enabled using a bit field @stats passed as the function argument. A few sample stats groups that this API will support: VIR_DOMAIN_STATS_STATE VIR_DOMAIN_STATS_CPU VIR_DOMAIN_STATS_BLOCK VIR_DOMAIN_STATS_INTERFACE (Note that this is only an example, the initial implementation supports only VIR_DOMAIN_STATS_STATE while others will be added later.) the returned typed params will use the following scheme state.state = VIR_DOMAIN_RUNNING state.reason = VIR_DOMAIN_RUNNING_BOOTED (the actual values according to the enum) cpu.count = 8 cpu.0.state = running cpu.0.time = 1234

Snapshots and block-copy have a flag that forces qemu to re-use existing file. Our docs weren't exactly clear on what the existing file should contain for this to actually work.
