I struggeled for a while with Debian Squeeze, trying to persuade it to run as a libvirt/kvm guest on my Ubuntu 12.04 host. After successful installation, the guests failed to boot the kernel with the messages:
Loading Linux 2.6.32-5-amd ...
unaligned pointer 0x8ebf0002
Aborted. Press any key to exit.
For my own reference, I record here the solution I just found after trying all sorts of things like installing different versions of grub into the virtual machine:
In the week of February 27 to March 2, 2012, a few Samba developers accepted an invitation by Microsoft and attended an SMB2.2 testing opportunity at Microsofts Enterprise Engineering Center in Redmond. Jeremy Allison, Steve French, Volker Lendecke, Chris Hertel, Christian Ambach, Matthieu Patou and I found our way to Redmond with Stefan Metzmacher participating to some extent via IRC and mumble. For me, the event was a big success, and I am happy that I finally made up my mind to go there. This is my personal report.
