As this information is not that easy to come by, here is a sample code for domain xml file. You have to specify driver tag with attribute type set to the image type. (Or alternatively, as described in security notice, adjust the 'allow_disk_format_probing' option in /etc/libvirt/qemu.conf)
Example: <disk type='file' device='disk'> <driver type='qcow2'/> <source file='myDisk.qcow2'/> ... </disk> -- Disk image type defaults to raw since 0.7.5-5ubuntu27.5 https://bugs.launchpad.net/bugs/667986 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
