"query-block-jobs" QMP command returns all running block jobs at once, while qemuMonitorBlockJobInfo would only report one. This is not very nice in case we need to check several block jobs. This patch refactors the monitor code to always parse all block jobs and store them in a hash. Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

Rather than have a separate routine to parse the alias of an iothread returned from qemu in order to get the iothread_id value, parse the alias when returning and just return the iothread_id in qemuMonitorIOThreadInfoPtr This set of patches removes the function, changes the "char *name" to "unsigned int" and handles all the fallout.

qemuDomainBlockJobImpl become an unmaintainable mess over the years of adding new stuff to it. This patch starts splitting up individual functions from it until it can be killed entirely. In bulk this will add lines of code rather than delete them but it will be traded for maintainability.

My intention is to split qemuMonitorJSONBlockJob() into simpler separate functions for every block job type. Since the error handling code is the same for all block jobs, this patch extracts the code into a separate function that will later be reused in more places. With the new helper qemuMonitorJSONErrorIsClass we can save a few function calls as we can extract the error object once.
-
由 Peter Krempa 提交于
Split out the function that checks the actual error class string into a separate helper as it will be useful later and refactor qemuMonitorJSONHasError to return bool type and remove few useless checks. Basically virJSONValueObjectHasKey are useless here since the next call to virJSONValueObjectGet is checking the return value again (which can't fail at that point). By removing the first check we save a function call.

When using 'dimm' memory devices with qemu, some of the information like the slot number and base address need to be reloaded from qemu after process start so that it reflects the actual state. The state then allows to use memory devices across migrations.

In qemu 2.3, the migration status will include 'cancelling' in the window between when an asynchronous cancel has been requested and when the migration is actually halted. Previously, qemu hid this state and reported 'active'. Libvirt manages the sequence okay even when the string is unrecognized (that is, it will report an unknown state: Migration: [ 69 %]^Cerror: internal error: unexpected migration status in cancelling. but the migration is still cancelled), but recognizing the string makes for a smoother user experience. * src/qemu/qemu_monitor.h (QEMU_MONITOR_MIGRATION_STATUS_CANCELLING): Add enum. * src/qemu/qemu_monitor.c (qemuMonitorMigrationStatus): Map it. * src/qemu/qemu_migration.c (qemuMigrationUpdateJobStatus): Adjust clients. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONGetMigrationStatusReply): Likewise.

https://bugzilla.redhat.com/show_bug.cgi?id=1199182 documents that after a series of disk snapshots into existing destination images, followed by active commits of the top image, it is possible for qemu 2.2 and earlier to end up tracking a different name for the image than what it would have had when opening the chain afresh. That is, when starting with the chain 'a <- b <- c', the name associated with 'b' is how it was spelled in the metadata of 'c', but when starting with 'a', taking two snapshots into 'a <- b <- c', then committing 'c' back into 'b', the name associated with 'b' is now the name used when taking the first snapshot. Sadly, older qemu doesn't know how to treat different spellings of the same filename as identical files (it uses strcmp() instead of checking for the same inode), which means libvirt's attempt to commit an image using solely the names learned from qcow2 metadata fails with a cryptic: error: internal error: unable to execute QEMU command 'block-commit': Top image file /tmp/images/c/../b/b not found even though the file exists. Trying to teach libvirt the rules on which name qemu will expect is not worth the effort (besides, we'd have to remember it across libvirtd restarts, and track whether a file was opened via metadata or via snapshot creation for a given qemu process); it is easier to just always directly ask qemu what string it expects to see in the first place. As a safety valve, we validate that any name returned by qemu still maps to the same local file as we have tracked it, so that a compromised qemu cannot accidentally cause us to act on an incorrect file. * src/qemu/qemu_monitor.h (qemuMonitorDiskNameLookup): New prototype. * src/qemu/qemu_monitor_json.h (qemuMonitorJSONDiskNameLookup): Likewise. * src/qemu/qemu_monitor.c (qemuMonitorDiskNameLookup): New function. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONDiskNameLookup) (qemuMonitorJSONDiskNameLookupOne): Likewise. * src/qemu/qemu_driver.c (qemuDomainBlockCommit) (qemuDomainBlockJobImpl): Use it.

The functions and their QMP and HMP implementations are no longer needed since everything is now done via the *AllStats functions.
-
由 Peter Krempa 提交于
Our virDomainBlockStatsFlags API uses the old approach where, when it's called without the typed parameter array, returns the count of parameters supported by qemu. The supported parameter count is obtained via separate monitor calls which is a waste since we can calculate it when gathering the data. This patch adds code to the qemuMonitorGetAllBlockStatsInfo workers that allows to track the count of supported fields reported by qemu and will allow to remove the old duplicate code.
-
由 Peter Krempa 提交于
The function that is extracting block stats data from the QMP monitor reply contains a lot of repeated code. Since I'd be changing each of the copies in the next patch, lets convert it to a macro right away.

The error count statistic is not supported by qemu, so there's no need to pass the variables around if the result is ignored anyways.

QEMU internally updates the size of video memory if the domain XML had provided too low memory size or there are some dependencies for a QXL devices 'vgamem' and 'ram' size. We need to know about the changes and store them into the status XML to not break migration or managedsave through different libvirt versions. The values would be loaded only if the "vgamem_mb" property exists for the device. The presence of the "vgamem_mb" also tells that the "ram_size" and "vram_size" exists for QXL devices.

The function queries the block devices visible to qemu ('query-block') and parses the qemu's output. The info is returned in a hash table which is expected to be pre-filled by qemuMonitorJSONGetAllBlockStatsInfo(). However, in the next patch we are not going to call the latter function at all, so we should make the former function add devices into the hash table if not found there.

Improve the monitor function to also retrieve the guest state of character device (if provided) so that we can refresh the state of virtio-serial channels and perhaps react to changes in the state in future patches. This patch changes the returned data from qemuMonitorGetChardevInfo to return a structure containing the pty path and the state for all the character devices. The change to the testsuite makes sure that the data is parsed correctly.

We used to set migration capabilities only when a user asked for them in flags. This is fine when migration succeeds since the QEMU process is killed in the end but in case migration fails or if it's cancelled, some capabilities may remain turned on with no way to turn them off. To fix that, migration capabilities have to be turned on if requested but explicitly turned off in case they were not requested but QEMU supports them. https://bugzilla.redhat.com/show_bug.cgi?id=1163953Signed-off-by: NJiri Denemark <jdenemar@redhat.com>
