package nova-compute-qemu not installed failed to install/upgrade: trying to overwrite /etc/nova/nova-compute.conf , which is also in package nova-compute-kvm 2012.1-0ubuntu1

The two packages are trying to write to the same conf file. No experience with either of them just trying to install. On the surface my guess is that it seems they either:
need separate conf files,
need to share the same conf file or
the installer should get a flag to remove the existing package and its conf file prior to installing the new one.

Someone more familiar than I needs to make the call on what the actual solution might be.

Sorry I was not more helpful.
