Public bug reported:
Binary package hint: vmbuilder
libvirt 0.8.3 and later (and the upcoming libvirt update for lucid-
security) does not probe qemu disks for the image format and defaults to
'raw' when the format is not specified in the XML. This breaks vmbuilder
because the version in maverick does not specify a format in the XML.
WORKAROUND:
After creating, use '/usr/sbin/libvirt-migrate-qemu-disks'. Should be able to
also use the '--raw' option when running vmbuilder (need to create the disk
first when using '--raw', eg: 'qemu-img create foo.img 2G'), but I can't seem
to get this to work right.
TEST CASE (in maverick release):
$ sudo vmbuilder kvm ubuntu --suite lucid --flavour virtual --arch i386 -o
--libvirt qemu:///system
$ virsh start ubuntu
$ virt-viewer ubuntu
At this point the VM has started, but shows 'No bootable devices'
