I am using QEMU/KVM, using Live Migrations like this:
virsh migrate --live ${name} qemu+ssh://${DESTINATION}/system
My question, running this command makes it hang in the foreground. Is there a way for this to return immediately, so I can just poll for the migration status?
Not at the moment, but it might be worth adding a 'migrate --detach' flag for that purpose, then using job control commands to track progress independently.
Also, is there a way to _cancel_ a migration?
Hit Ctrl-C (or any other approach for sending SIGINT to virsh).
I see the --timeout option, however if a given timeout is reached I would rather have the ability to cancel the migration than force the suspend.
I do see there is a QEMU api migrate_cancel..eg:
virsh qemu-monitor-command ${name} --pretty '{"execute":"migrate_cancel"}'
Is that the only way to cancel a migration using libvirt?
That way is unsupported. The supported way (and the way used by ctrl-C during 'virsh migrate') is to call virDomainAbortJob(). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
