Kernel panic with Openstack Virtual Appliances 12.0-squeeze

Hi all folks,

we have been using Turnkey Virtual Appliances 11.3-lucid-x86 based for Openstack for a while and they have worked like a breeze.

We have started to test the new 12.0-squeeze based virtual appliances, but we get this error on boot with a couple of virtual appliances:

[    0.524819] List of all partitions:
[    0.525226] No filesystem could mount root, tried:
[    0.525794] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

We are using the following following configuration:

- StackOps Distro 0.6 / Openstack Essex Release

- KVM hypervisor

- turnkey-drupal7-12.0-squeeze-x86-openstack.tar.gz

- turnkey-owncloud-12.0-squeeze-x86-openstack.tar.gz
 

We stopped testing anymore virtual appliances before getting feedback from the Turnkey forums.

Anybody has the same problem? Any suggestions?

Regards
