Cheatsheet
Clone a virtual machine
Copy the xml file found in /etc/libvirt/ to myclone.xml
You will problable need a new MAC address, one way you find [here]
echo 'import virtinst.util ; print\ virtinst.util.uuidToString(virtinst.util.randomUUID())' | python
If you get "ImportError: No module named virtinst.util"
Edit myclone.xml:
replace the string in <uuid> with "myclone"
Install to drbd
kvm -name squeeze1 -usbdevice tablet -vnc :1 -hda /dev/drbd0 -cdrom /tmp/debiansqueeze.iso -boot d -m 384
And then use -boot c to actually boot it:
kvm -name squeeze1 -usbdevice tablet -vnc :1 -hda /dev/drbd0 -boot c -m 384
virt-install -d --name=squeeze --ram 512 --disk path=/dev/drbd/by-res/squeeze,bus=virtio,cache=none --virt-type=kvm --network bridge=br0,model=virtio --vnc --accelerate --location=http://ftp.debian.org/debian/dists/squeeze/main/installer-amd64/
and start using
kvm start squeeze
