Comment 10 for bug 1391673

I upgraded to 15.04beta and face this issue again

virt-manager 1:1.0.1-4ubuntu2

It is just a problem with this single profile. Other profiles do work.

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 91, in cb_wrapper

libvirtError: internal error: process exited while connecting to monitor: 2015-02-22T11:02:14.744134Z qemu-system-x86_64: -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/channel/target/fedora20.org.qemu.guest_agent.0,server,nowait: Failed to bind socket: No such file or directory

The path /var/lib/libvirt/qemu/channel/target/ seems to be dynamically created, as it does not belong to any packages in vivid. Creating it with proper permissions does not make any difference.
