Change subject: core: Allow to migrate a paused VM with Post-copy policy ...................................................................... core: Allow to migrate a paused VM with Post-copy policy Libvirt does not allow to migrate a VM in Paused state with post-copy migration. If migration policy of a cluster contains a "postcopy" action, every attempt to migrate a paused VM fails because libvirt returns an error, not allowing migration to start. On the other side, the current Post-copy migration policy uses post-copy only as last resort, when a regular migration stalls. It is unlikely that migration will be stalling when migrating a paused VM, so it is safe to use a Post-copy policy with it. Libvirt bug have been open for this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1464792 This patch introduces a workaround: MigrateVmCommand will filter a "postcopy" action out of the effective migration policy, if the VM is in Paused state. This helps to avoid libvirt error and allows to migrate such a VM in a cluster with Post-copy migration policy.
