libvirt users - Mar 2013 - Unable to connect to console to recently cloned VM's

Hi all.

I was using libvirt under Debian squeeze (I guess it was
0.8.3-5+squeeze4 or something similar). I was able to clone machines
with below command:

sudo virt-clone  --connect=qemu:///system -o template -n
template_clone -f /var/lib/libvirt/images/template_clone.qcow2

After that I was able to start the VM and connect to the console:

sudo virsh console template_clone

I recently Installed libvirt on a Debian wheezy ( libvirt-bin
0.9.12-11). I recuperated the old "template" VM, and I tried to create
a new one successfully.

What I CAN do:

1. Start both VM's (the template imported from the old installation
and the new one)
2. Connect to the console of both VM's
3. Clone them

What I CAN'T do:

1. Access to the console of the cloned VM, they stalled at the prompt.

Just in case config of the VM:

<domain type='kvm'>
  <name>template-1.dev.jj.com</name>

    </controller>
    <interface type='network'>
      <mac address='52:54:00:c0:c6:24'/>
      <source network='default'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00'
slot='0x03'
function='0x0'/>
    </interface>
    <serial type='pty'>
      <target port='0'/>
    </serial>
    <console type='pty'>
      <target type='serial' port='0'/>
    </console>
    <memballoon model='virtio'>
      <address type='pci' domain='0x0000' bus='0x00'
slot='0x05'
function='0x0'/>
    </memballoon>
  </devices>
</domain>

Is somebody else experiencing the same problem? I'm not sure even that
the clones VM is working, since I'm able to start it up but no connect
to it.

Thanks.

Javier

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
