[libvirt-users] error: internal error: Failed to reserve port 5908

[Bill Kenworthy]

After saving a particular VM running WinXP, any attempt to resume it
(even when no other VM's are running) generates the following error:

olympus ~ # virsh restore /var/lib/libvirt/qemu/save/WinXP.save
error: Failed to restore domain from /var/lib/libvirt/qemu/save/WinXP.save
error: internal error: Failed to reserve port 5908


This started sometimes towards the end of last year with only the WinXP
VM.  libvirt is supporting a number of windows versions and a heap of
linux VM's but its only WinXP that does this.

Can someone give a hint as to what is causing it?
