[Pkg-libvirt-maintainers] Bug#565767: libvirt-bin: VM doesn't work after upgrade: qemu: Could not initialize device 'tap'

[Tino Keitel]

Package: libvirt-bin
Version: 0.7.5-4
Severity: normal

My VMs with tap device network emulation don't work after upgrading from
0.7.2 in squeeze to the sid version. I get a requester with this message:

Error starting domain: internal error unable to start guest: warning: could
not configure /dev/net/tun: no virtual network emulation
qemu: Could not initialize device 'tap'

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 588, in
run_domain
    vm.startup()
  File "/usr/share/virt-manager/virtManager/domain.py", line 150, in startup
    self._backend.create()
  File "/usr/lib/python2.5/site-packages/libvirt.py", line 293, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error unable to start guest: warning: could not
configure /dev/net/tun: no virtual network emulation
qemu: Could not initialize device 'tap'

My network configuration in the VM looks like this:

    <interface type='ethernet'>
      <mac address='54:52:00:3a:13:4b'/>
      <target dev='m0d0'/>
      <model type='e1000'/>
    </interface>
