[Pkg-libvirt-maintainers] Bug#607791: libvirt-bin: No support for qemu in command 'attach-disk'

[Francesc Guasch]

Package: libvirt-bin
Version: 0.8.3-5
Severity: normal

I have libvirt-bin 0.8.3-5 in squeeze. I am trying to attach more disks to a
kvm image. The qemu driver is unsupported.

Attaching a new disk using virsh won't work:

    # virsh attach-disk guest_server file.img vdb --type=disk --driver=qemu
    error: No support for qemu in command 'attach-disk'

The only way to add a new disk is using driver=file. That is later unsupported
by kvm and the xml config file must be fixed manually:

    # virsh attach-disk guest_server file.img vdb --type=disk --driver=file
    Disk attached successfully

    # virsh stop guest_server
    # virsh start guest_server
    error: Failed to start domain sonja
   error: internal error unsupported driver name 'file' for disk
'/var/lib/libvirt/images/file.img'

I found a workaround changing the driver to from file to qemu using virsh edit.


It looks like it is fixed upsteam in release libvirt-0.8.2-8.el5
  https://bugzilla.redhat.com/show_bug.cgi?id=609422

Though dpkg -l libvirt-bin shows I have: libvirt-bin  0.8.3-5 this feature
still fails. Even with a different parameters suggested there:

    # virsh attach-disk guest_server file.img vdb --sourcetype block --driver
qemu --subdriver raw
    error: command 'attach-disk' doesn't support option --sourcetype
