[libvirt] [PATCH 1/3] fix migration of paused vms upon failure

This makes a small change on the failed-migration path. Up to now, all VMs that failed non-live migration after the "stop" command were restarted. This must not be done when the VM was paused in the first place. * src/qemu/qemu_driver.c (qemudDomainMigratePerform): Do not restart a paused VM that fails migration. Set paused state after "stop", reset it after failure. --- src/qemu/qemu_driver.c | 4 +++- 1 files changed, 3 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 356e4e7..44cec6c 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -7182,7 +7182,7 @@ qemudDomainMigratePerform (virDomainPtr dom, goto endjob; } - if (!(flags & VIR_MIGRATE_LIVE)) { + if (!(flags & VIR_MIGRATE_LIVE) && vm->state == VIR_DOMAIN_RUNNING) { qemuDomainObjPrivatePtr priv = vm->privateData; /* Pause domain for non-live migration */ qemuDomainObjEnterMonitorWithDriver(driver, vm); @@ -7193,6 +7193,7 @@ qemudDomainMigratePerform (virDomainPtr dom, qemuDomainObjExitMonitorWithDriver(driver, vm); paused = 1; + vm->state = VIR_DOMAIN_PAUSED; event = virDomainEventNewFromObj(vm, VIR_DOMAIN_EVENT_SUSPENDED, VIR_DOMAIN_EVENT_SUSPENDED_MIGRATED); @@ -7240,6 +7241,7 @@ endjob: } qemuDomainObjExitMonitorWithDriver(driver, vm); + vm->state = VIR_DOMAIN_RUNNING; event = virDomainEventNewFromObj(vm, VIR_DOMAIN_EVENT_RESUMED, VIR_DOMAIN_EVENT_RESUMED_MIGRATED); -- 1.6.5.2
