Guess I should add I have libvirt 0.9.2, as that's what ubuntu has packaged. On 06/06/2012 12:55 PM, Sean Abbott wrote:
So, I was attempting to use qemu snapshots with backing stores. The QEMU docs (http://wiki.qemu.org/Documentation/CreateSnapshot) make it sound like you simply point your qemu at the snapshot after it's creation, and you're golden.
When attempting this with libvirt, though, it fails.
I created a snapshot using the above tutorial. the resulting file is disk.0, and a qmeu-img info on it returns:
image: disk.0 file format: qcow2 virtual size: 29G (31457280000 bytes) disk size: 140K cluster_size: 65536 backing file: /var/lib/one/public/lin_client_current.qcow2 (actual path: /var/lib/one/public/lin_client_current.qcow2)
So that all looks groovy, right?
Then, I created (via opennebula) an xml deployment file like so: http://paste.ubuntu.com/1027145/
When I attempt to do a virsh create, I get the following errors:
virsh # create deployment.0 error: Failed to create domain from deployment.0 error: internal error process exited while connecting to monitor: file=/var/lib/one/vm/56/images/disk.0,if=none,id=drive-virtio-disk0,boot=on,format=qcow2,cache=none qemu-kvm: boot=on|off is deprecated and will be ignored. Future versions will reject this parameter. Please update your scripts. qemu-system-x86_64: -drive file=/var/lib/one/vm/56/images/disk.0,if=none,id=drive-virtio-disk0,boot=on,format=qcow2,cache=none,boot=on: could not open disk image /var/lib/one/vm/56/images/disk.0: Invalid argument
So...something isn't working. Is it possible to do this, or should I give up on this path?
Thanks!
