1. Editar:

sudo vim /etc/apt/sources.list

Y anyadir la siguiente linea:

deb http://backports.debian.org/debian-backports squeeze-backports main

2. Actualizar la cache de paquetes:

sudo aptitude update

3. Instalar la version de backports de los siguientes paquetes:

sudo aptitude -t squeeze-backports install libvirt-bin libvirt0 python-libvirt dnsmasq-base -R

4. Reiniciar el demonio libvirtd:

sudo /etc/init.d/libvirt-bin restart

First, check for a backport on <debian-backports>. If unavailable:

1) Add a deb-src line for sid (not a deb line!); ask me about <deb-src sid>

2) enable debian-backports (see <bdo>)

3)

aptitude update; aptitude install build-essential; aptitude build-dep packagename; apt-get -b source packagename

4) install the resultant debs. To change compilation options, see <package recompile>; for versions newer than sid see <uupdate>.
