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

18 Mar 2013

      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.

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:

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.
