Cheatsheet

Clone a virtual machine

Copy the xml file found in /etc/libvirt/ to myclone.xml

You will problable need a new random MAC address, one way you find [here] Also generate a new uuid (todo: get script)


Edit myclone.xml: -update <name>, <uuid>, <mac address, <disk><source>

then you will probably need to change things like IP address, /etc/hostname etc.

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
