So switching only the guest OS (keeping the host OS, domain XML and
everything) works, so how can the problem be anywhere else than the
guest OS? You might be, most probably, missing some kernel option.
What is the difference between the installer and the system installed?
Are they using the same kernel? Accessing the same things?

You're adding more configurations into the mix, let's skip that and only
talk about what you had before, the IDE and ubuntu/your distro.

Are there that many since 1.1.2? I don't think that much has changed.
But it should be solvable without updating (plus the update might not
fix it for you.
Let me try and recap what is happening :
On my custom embedded linux, using the same domain config xml, just
changing the disk drivers and/or the iso
Ubuntu.iso + ide disk drivers -> works
Ubuntu.iso + virio disk drivers -> does not work; errors when reading
from /dev/vda
customLinuxOS.iso + virtio drivers -> does not seem to work; kernel
panics and services stop working
On Ubuntu10.04 host, using the same domain config xml as before, just
changing the iso
Ubuntu.iso + virtio disk drivers -> vorks
customLinuxOS.iso + virtio drivers -> works
This sounds to me like a problem with kvm virtio drivers (since when using
ide drivers installing ubuntu as a guest works)
If there is anything I'm missing, or you think I should try ..I'm open to
trying it.
Thanks,
Andrei
