That's what I do.  Just as a warning, if you're using the libvirt
packages from Debian unstable, make sure you also install
linux-libc-dev from unstable before building qemu-kvm.

Otherwise, virtio networking will fail.  The reason is that qemu-kvm
will be built against the Lenny linux-libc-dev which does not have
IFF_VNET_HDR, while the libvirt was built against a newer
linux-libc-dev that did define IFF_VNET_HDR.  If they don't agree then
things break.

(just had to track this one down the other day)
