I can see already a Problem with the opennebula package.
It will no longer work, since it does not generate this information on the
domain xmls - it would not have this information anyway - else if it would
probe for the data type of the image, this - we are being told - being a

@nerling:
Whatever is creating the domain XML (ie with 'create' or 'define') needs
to add the driver name='qemu' type='foo'/ bit, after which it is
stored in the XML. If OpenNebula creates virtual machines and adds them
to libvirt, it must be adjusted for this. If OpenNebula is creating

Suggested release note text:
Previous libvirt versions would probe a qemu disk to determine its format and
did not require that the format be declared in the XML. This is considered a

Which is what I've been doing. The VM definitions will not
Jamin, your vm.xml does not contain enough information-- you must
specify the disk format when defining a new VM. Simply put, if you are
using a qcow2 disk you must specify driver name='qemu' type='qcow2'/
in the vm.xml you are using.

Jamie, I understand that the vm.xml does not contain enough information
for the version of libvirt in maverick. I understand that with
maverick's version one now has to supply a disk format. However, this

Sure applications change with versions. However, they normally also
