If you do `yum groupinstall Virtualization` you get virt-manager installed (and libvirtd), but not qemu. If you try to create a qemu/kvm connection in virt-manager you subsequently get a cryptic error message about not being able to connect to qemu:///system. This error is resolved by installing the `qemu` package.

In theory I suppose this is OK since virt-manager would still work with Xen, but AFAIK dom0 support isn't implemented in the 2.6.29 kernel, so in practice users must use KVM on Fedora 11. I think that virt-manager should depend on qemu for this reason, since Xen isn't really a viable alternative for F11 users.

At the very least, the Virtualization group should probably provide qemu, since that provides a looser dependency.

This is all wrt the fedora 11 beta. I have virt-manager version 0.7.0 release 4.fc11.
