there are newer builds of qemu and libvirt in the newer releases of 
ubuntu and so it may be possible to use those. 
https://help.ubuntu.com/community/PinningHowto gives some good 
information about how to either install a newer package version from a 
newer release (apt-pinning) or how to build a newer version 
('recommended alternative to pinning'). the versions in the instructions 
are old but you should be able to just use precise and quantal where 
appropriate. i'm pretty sure that installing the quantal build of 
qemu-kvm through apt-pinning will just work. getting an updated libvirt 
might be a little more problematic due to possible changes in the apis 
for client applications. you may have to update any apps using libvirt 
as well.

i briefly tried to rebuild the quantal version of qemu-kvm (1.2) using 
the instructions on the PinningHowto on a 12.04 workstation. the quantal 
version has some additional build dependencies that didn't get fulfilled 
during the apt-get build-dep stage. you should be able to just install 
any packages it says are missing. on my system, i had to `sudo apt-get 
install libbluetooth-dev libbrlapi-dev libjpeg-dev xfslibs-dev` to get 
the necessary dependencies. the resulting .debs should just be in the 
current working directory that you can install through dpkg. i didn't 
test installing since i already have other custom things going on and i 
haven't tried rebuilding libvirt.

good luck.
