how you manage to preform snapshot with the raw format in qemu-kvm VMs?
# Create a snapshot called backup of testvm's image in the rbd pool: rbd snap create --read-only rbd/testvm@backup # Dump the snapshot to file rbd export rbd/testvm@backup testvm-backup.img # Delete the snapshot rbd snap rm rbd/testvm@backup
cloud you please let me know how you use the ceph as backend storage of qemu-kvm, as if i google it, most of the ceph application is used for OpenStack, but not simply pure qemu-kvm.
I'm using pure libvirt/qemu-kvm too. Last I checked, virt-install doesn't support using rbd volumes directly. There's two ways I know of to get around this:
1. Create the VM using a file-based qcow2 image then convert to rbd 2. Modify the XML produced by virt-install before the VM is started I can provide detailed steps for these if you need them.
