I upgraded to Ubuntu 12.04.1 and now libvirt (via open nebula) successfully runs vms but they aren't finding the 2 drives (specifically, the
boot drive). One is "hd" the other is "cdrom".
The machine boots but fails and displays something like "
boot media not found hd" (this was in a vnc terminal and I didn't copy the output anywhere so that's not the verbatim message).
I tried constructing a new disk using the new version of qemu (via vmbuilder) and this new machine has the same problem as the old machine.
In case it matters (I can't see why it would) I'm using open nebula to manage the machines.
There's nothing relevant in any of the logs: syslog, libvirtd, oned. Which is to say nothing interesting/anomalous is reported when the machine is brought up.
