Detect and react on situations when libvirtd was restarted or killed when a job was active.
-
由 Jiri Denemark 提交于
If libvirtd is restarted when a job is running, the new libvirtd process needs to know about that to be able to recover and rollback the operation.

Query commands are safe to be called during long running jobs (such as migration). This patch makes them all work without the need to special-case every single one of them. The patch introduces new job.asyncCond condition and associated job.asyncJob which are dedicated to asynchronous (from qemu monitor point of view) jobs that can take arbitrarily long time to finish while qemu monitor is still usable for other commands. The existing job.active (and job.cond condition) is used all other synchronous jobs (including the commands run during async job). Locking schema is changed to use these two conditions. While asyncJob is active, only allowed set of synchronous jobs is allowed (the set can be different according to a particular asyncJob) so any method that communicates to qemu monitor needs to check if it is allowed to be executed during current asyncJob (if any). Once the check passes, the method needs to normally acquire job.cond to ensure no other command is running. Since domain object lock is released during that time, asyncJob could have been started in the meantime so the method needs to recheck the first condition. Then, normal jobs set job.active and asynchronous jobs set job.asyncJob and optionally change the list of allowed job groups. Since asynchronous jobs only set job.asyncJob, other allowed commands can still be run when domain object is unlocked (when communicating to remote libvirtd or sleeping). To protect its own internal synchronous commands, the asynchronous job needs to start a special nested job before entering qemu monitor. The nested job doesn't check asyncJob, it only acquires job.cond and sets job.active to block other jobs.

EnterMonitor and ExitMonitor methods are very similar to their *WithDriver variants; consolidate them into EnterMonitorInternal and ExitMonitorInternal to avoid (mainly future) code duplication.
-
由 Jiri Denemark 提交于
This avoids code duplication and also avoids relying on good luck that ignore_value(virDomainObjUnref(obj)) doesn't set errno.

Incrementally running 'make syntax-check' on a tree previously built after commit 62dee6fa but before 44036460 fails sc_po_check (because the generated qemu_dispatch.h gained translatable strings). This is a followup to commit addaa537 for that scenario. * cfg.mk (sc_po_check): Add another prereq. ($(srcdir)/daemon/qemu_dispatch.h): Add rule.

Given a PID, the QEMU driver reads /proc/$PID/cmdline and /proc/$PID/environ to get the configuration. This is fed into the ARGV->XML convertor to build an XML configuration for the process. /proc/$PID/exe is resolved to identify the full command binary path After checking for name/uuid uniqueness, an attempt is made to connect to the monitor socket. If successful then 'info status' and 'info kvm' are issued to determine whether the CPUs are running and if KVM is enabled. * src/qemu/qemu_driver.c: Implement virDomainQemuAttach * src/qemu/qemu_process.h, src/qemu/qemu_process.c: Add qemuProcessAttach to connect to the monitor of an existing QEMU process

log2() is heavy when ffs() can do the same thing. But ffs() requires gnulib support for mingw.

The drivers were accepting domain configs without checking if those were actually meant for them. For example the LXC driver happily accepts configs with type QEMU. Add a check for the expected domain types to the virDomainDefParse* functions.

Kernel cmdline args can be passed to xen pv domains even when a bootloader is specified. The current config-to-sxpr mapping ignores cmdline when bootloader is present. Since the xend sub-driver is used with many xen toolstack versions, this patch takes conservative approach of adding an else block to existing !def->os.bootloader, and only appends sxpr if def->os.cmdline is non-NULL.

If virDomainSaveConfig() failed, we will return NULL to source, and the vm is still available to restart during confirm() step in v3 protocol. So we should kill it off in qemuMigrationFinish(). In v2 protocol, we should not set vm to NULL, because we hold a reference of vm and should unrefernce it.
