[libvirt-users] Unable to connect to console to recently cloned VM's

[Javi Legido]

Hi all.

I re-installed my KVM server with Debian stable again (squeeze) and it
works again (libvirt-bin 0.8.3-5+squeeze5).

I'll fill a bug with Debian, because maybe libvirt-bin 0.9.12-11 has
some kind of bug.

PD: I'm using RAID 1 software

Regards.

Javier
