Migrating libvirt guest machines from one host to another.

In this video, I look into migrating virtualized machines. Both using the normal disk backend and Ceph to see the difference.

If you need to move the guest with all the storage devices to a new host.

virsh migrate --live --persistent --undefinesource --copy-storage-all --verbose [guest-name] qemu+ssh://node10/system

If you need to move the guest with centrally hosted storage to a new host.

virsh migrate --live --persistent --undefinesource --verbose migrate-test qemu+ssh://node10/system
