Cool to hear that. Anyway, upgrading to Qemu 1.3 on Ubuntu 12.04 was 
pretty straight for me and not regressive :
apt-get install zlib1g-dev libsdl1.2-dev libpcap-dev texinfo autoconf 
libtool build-essential
wget http://wiki.qemu-project.org/download/qemu-1.3.1.tar.bz2
tar jxvf qemu-1.3.1.tar.bz2
cd qemu-1.3.1
./configure --target-list=x86_64-linux-user,x86_64-softmmu # Depending 
on your platform of course
make
sudo make install

It will deploy qemu in /usr/local/bin/ while the Ubuntu qemu-1.0 package 
is based in /usr/bin.

So as to get it work with libvirt and nova, you have to make sure you 
have hvm capabilities (check with 'virsh capabilities'), and if not, 
this is due to the fact that libvirt is requesting 
/usr/bin/qemu-system.<platform>

In order to fix this, a quick "mv /usr/bin/qemu-system.<platform> 
/usr/bin/qemu-system.<platform>.0 && mv 
/usr/local/bin/qemu-system.<platform> /usr/bin' does the trick.

Hopefully, nova is following the path for qemu-img, which makes 
unnecessary to switch versions as above.
