Just true/false is good enough for it. Also use it directly from the parsed URI instead of caching it in esxPrivate.

When the session has expired then multiple threads can race while reestablishing it. This race condition is not that critical as it requires a special usage pattern to be triggered. It can only happen when an application doesn't do API calls for quite some time (the session expires after 30 min inactivity) and then multiple threads doing simultaneous API calls and end up doing simultaneous calls to esxVI_EnsureSession.

virsh didn't call virInitialize(), which (among other things) initializes virLastErr thread local variable. As a result of that, virsh could just segfault in virEventRegisterDefaultImpl() since that is the first call that touches (resets) virLastErr. I have no idea what lucky coincidence made this bug visible but I was able to reproduce it in 100% cases but only in one specific environment which included building in sandbox.

Instead of specifying the type of the managed object directly specify the ServiceContent member name. This way the mapping dictionary can be removed.

By running the doTunnelSendAll code in a separate thread, the main thread can do qemuMigrationWaitForCompletion as with normal migration. This in turn ensures that job signals work correctly and that progress monitoring can be done * src/qemu/qemu_migration.c: Run tunnelled migration in separate thread

Cancelling the QEMU migration may cause QEMU to flush pending data on the migration socket. This may in turn block QEMU if nothing reads from the other end of the socket. Closing the socket before cancelling QEMU migration avoids this possible deadlock. * src/qemu/qemu_migration.c: Close sockets before cancelling migration on failure

The 'nbytes' variable was not re-initialized to the buffer size on each iteration of the tunnelled migration loop. While saferead() will ensure a full read, except on EOF, it is clearer to use the real buffer size * src/qemu/qemu_migration.c: Always read full buffer of data

The qemuMigrationWaitForCompletion method contains a loop which repeatedly queries QEMU to check migration progress, and also processes job signals (pause, setspeed, setbandwidth, cancel). The tunnelled migration loop does not currently support this functionality, but should. Refactor the code to allow it to be used with tunnelled migration.

Implement the v3 migration protocol, which has two extra steps, 'begin' on the source host and 'confirm' on the source host. All other methods also gain both input and output cookies to allow bi-directional data passing at all stages. The QEMU peer2peer migration method gains another impl to provide the v3 migration. This finally allows migration cookies to work with tunnelled migration, which is required for Spice seamless migration & the lock manager transfer * src/qemu/qemu_driver.c: Wire up migrate v3 APIs * src/qemu/qemu_migration.c, src/qemu/qemu_migration.h: Add begin & confirm methods, and peer2peer impl of v3

Merge the doNonTunnelMigrate2 and doTunnelMigrate2 methods into one doPeer2PeerMigrate2 method, since they are substantially the same. With the introduction of v3 migration, this will be even more important, to avoid massive code duplication. * src/qemu/qemu_migration.c: Merge tunnel & non-tunnel migration

The v2 migration protocol was accidentally missing out the finish step, when prepare succeeded, but returned an invalid URI * src/libvirt.c: Teardown VM if prepare returns invalid URI
-
由 Daniel P. Berrange 提交于
To facilitate the introduction of the v3 migration protocol, the doTunnelMigrate method is refactored into two pieces. One piece is intended to mirror the flow of virDomainMigrateVersion2, while the other is the helper for setting up sockets and processing the data. Previously socket setup would be done before the 'prepare' step, so errors could be dealt with immediately, avoiding need to shut off the destination QEMU. In the new split, socket setup is done after the 'prepare' step. This is not a serious problem, since the control flow already requires calling 'finish' to tear down the destination QEMU upon several errors. * src/qemu/qemu_migration.c:

Use the graphics information from the QEMU migration cookie to issue a 'client_migrate_info' monitor command to QEMU.

Extend the QEMU migration cookie structure to allow information about the destination host graphics setup to be passed by to the source host.

The migration protocol has support for a 'cookie' parameter which is an opaque array of bytes as far as libvirt is concerned. Drivers may use this for passing around arbitrary extra data they might need during migration. The QEMU driver needs to do a few things: - Pass hostname/uuid to allow strict protection against localhost migration attempts - Pass SPICE/VNC server port from the target back to the source to allow seamless relocation of client sessions - Pass lock driver state from source to destination This patch introduces the basic glue for handling cookies but only includes the host/guest UUID & name. * src/libvirt_private.syms: Export virXMLParseStrHelper * src/qemu/qemu_migration.c, src/qemu/qemu_migration.h: Parsing and formatting of migration cookies * src/qemu/qemu_driver.c: Pass in cookie parameters where possible * src/remote/remote_protocol.h, src/remote/remote_protocol.x: Change cookie max length to 16384 bytes

Migration just seems to go from bad to worse. We already had to introduce a second migration protocol when adding the QEMU driver, since the one from Xen was insufficiently flexible to cope with passing the data the QEMU driver required. It turns out that this protocol still has some flaws that we need to address. The current sequence is * Src: DumpXML - Generate XML to pass to dst * Dst: Prepare - Get ready to accept incoming VM - Generate optional cookie to pass to src * Src: Perform - Start migration and wait for send completion - Kill off VM if successful, resume if failed * Dst: Finish - Wait for recv completion and check status - Kill off VM if unsuccessful The problems with this are: - Since the first step is a generic 'DumpXML' call, we can't add in other migration specific data. eg, we can't include any VM lease data from lock manager plugins - Since the first step is a generic 'DumpXML' call, we can't emit any 'migration begin' event on the source, or have any hook that runs right at the start of the process - Since there is no final step on the source, if the Finish method fails to receive all migration data & has to kill the VM, then there's no way to resume the original VM on the source This patch attempts to introduce a version 3 that uses the improved 5 step sequence * Src: Begin - Generate XML to pass to dst - Generate optional cookie to pass to dst * Dst: Prepare - Get ready to accept incoming VM - Generate optional cookie to pass to src * Src: Perform - Start migration and wait for send completion - Generate optional cookie to pass to dst * Dst: Finish - Wait for recv completion and check status - Kill off VM if failed, resume if success - Generate optional cookie to pass to src * Src: Confirm - Kill off VM if success, resume if failed The API is designed to allow both input and output cookies in all methods where applicable. This lets us pass around arbitrary extra driver specific data between src & dst during migration. Combined with the extra 'Begin' method this lets us pass lease information from source to dst at the start of migration Moving the killing of the source VM out of Perform and into Confirm, means we can now recover if the dst host can't successfully Finish receiving migration data.

The hvsupport.html.in file is forever out of date. By annotating the driver struct tables in each driver with version information, we can auto-generate the hvsupport.html.in file. Annotating the drivers will be mandatory for new patches, ensuring hvsupport.html.in is never out of date again. * docs/hvsupport.html.in: Delete * hvsupport.pl: Script to generate hvsupport.html.in * Makefile.am: Autogenerate hvsupport.html.in

Change all the driver struct initializers to use the C99 style, leaving out unused fields. This will make it possible to add new APIs without changing every driver. eg change: qemudDomainResume, /* domainResume */ qemudDomainShutdown, /* domainShutdown */ NULL, /* domainReboot */ qemudDomainDestroy, /* domainDestroy */ to .domainResume = qemudDomainResume, .domainShutdown = qemudDomainShutdown, .domainDestroy = qemudDomainDestroy, And get rid of any existing C99 style initializersr which set NULL, eg change .listPools = vboxStorageListPools, .numOfDefinedPools = NULL, .listDefinedPools = NULL, .findPoolSources = NULL, .poolLookupByName = vboxStoragePoolLookupByName, to .listPools = vboxStorageListPools, .poolLookupByName = vboxStoragePoolLookupByName,

A qemu domain can get paused when libvirtd is stopped (e.g., because of I/O error) so we should check its current state when reconnecting to it.
