[Bug 665531] Re: [lucid] libvirt does not support format=host_device

[Jamie Strandboge]

Actually, I see the problem:
$ cat /tmp/tserver.xml | /usr/lib/libvirt/virt-aa-helper -r --uuid libvirt-c04cd76d-029b-7644-13ab-c2d144543ea2 --dryrun -p 0
libvir: Domain Config error : internal error unknown disk format 'host_device' for /dev/virtual/tserver
virt-aa-helper: error: invalid VM definition

$ cat /tmp/tserver.xml | /usr/lib/libvirt/virt-aa-helper -r --uuid libvirt-c04cd76d-029b-7644-13ab-c2d144543ea2 --dryrun -p 1
libvir: Domain Config error : internal error unknown disk format 'host_device' for /dev/virtual/tserver
virt-aa-helper: error: invalid VM definition

If you change tserver.xml to use:
      <driver name='qemu' type='raw'/>

instead of:
      <source dev='/dev/virtual/tserver'/>

It works as expected:
$ cat /tmp/tserver.xml | /usr/lib/libvirt/virt-aa-helper -r --uuid libvirt-c04cd76d-029b-7644-13ab-c2d144543ea2 --dryrun -p 0

libvirt 0.8.3 from Ubuntu 10.10 doesn't support host_device at all:
$ cat ./tserver.xml | /usr/lib/libvirt/virt-aa-helper -r --uuid libvirt-c04cd76d-029b-7644-13ab-c2d144543ea2 --dryrun -p 0
