I’ve found that the best way to test something in virtualization is through snapshots.
But why snapshot the running/active virtual machine and not the backup/clone virtual machine ?
# virsh list --all
Id Name State
----------------------------------------------------
- winxp running
- winxpclone shut off
Check the clone disk format:
# qemu-img info winxpclone.disk
image: winxpclone.disk
file format: raw
virtual size: 5.0G (5368709120 bytes)
disk size: 3.1G
And remember to convert the raw disk to qcow2 first:
# qemu-img convert -f raw winxpclone.disk -O qcow2 winxpclone.qcow2
And then edit your clone:
# virsh edit winxpclone
to use the qcow2 disk
and finally:
# virsh snapshot-create winxpclone
Domain snapshot 1341315833 created
List the snapshots:
# virsh snapshot-list winxpclone
Name Creation Time State
