Hi,

i have inserted:

<channel type='unix'>
      <source mode='bind'
path='/var/lib/libvirt/qemu/channel/target/sles11.org.qemu.guest_agent.0'/
>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
      <address type='virtio-serial' controller='0' bus='0' port='2'/>
</channel>


I didn't insert the path, it was added automatically, the same with
"<address type='virtio-serial' controller='0' bus='0' port='2'/>".
I tried already port 1 and 2, but get this error:

sunhb58820:~/libvirt_1.2.11 # virsh start sles11
error: Failed to start domain sles11
error: internal error: process exited while connecting to monitor:
