How to take snapshot of VM which is booted from volume??
Hello All,
In my OpenStack cluster(Newton) I have VM's which are booted from volume(Ceph based). I have one more Openstack cluster(Queens) which is completely separated from the Newton based one. I want to take the snapshot of VM's running in Newton based cluster and upload the snapshots in my Queens based cluster and create VM's out of them. But when I took snapshot of VM's which are booted from volume the snapshot size is showing 0bytes. How can I take snapshot of VM booted from volume so that I can upload it in other cluster??
