 +### How to configure MAAS to be able to boot virtual machines with virsh
 +
 +The libvirt-bin package needs to be installed to get the virsh command
 +```bash
 +sudo apt-get -y install libvirt-bin
 +```
 +If you want to use ssh you'll need to generate a ssh key pair for the maas user. 
 +By default there is no home directory created for the maas user.
 +```bash
 +sudo mkdir -p ~maas
 +sudo chown maas:maas ~maas
 +```
 +Add a login shell for the maas user (we'll only need this for the ssh-copy-id command later; 
 +if you're putting ssh keys in place manually or using a different mechanism, this step isn't strictly needed):
 +```bash
 +sudo chsh -s /bin/bash maas
 +```
 +
 +Generate a SSH keypair as the maas user (hit enter three times to accept the default path and empty password):
 +```bash
 +sudo -u maas ssh-keygen
 +Generating public/private rsa key pair.
 +Enter file in which to save the key (/home/maas/.ssh/id_rsa): 
 +Created directory '/home/maas/.ssh'.
 +Enter passphrase (empty for no passphrase): 
 +Enter same passphrase again: 
 +Your identification has been saved in /home/maas/.ssh/id_rsa.
 +Your public key has been saved in /home/maas/.ssh/id_rsa.pub.
 +```
 +Then add the public key to ~ubuntu/.ssh/authorized_keys on the vm server so virsh can use ssh without a password:
 +```bash
 +sudo -u maas -i ssh-copy-id ubuntu@192.168.122.1
 +```
 +As the maas user, test virsh commands against libvirt at 192.168.122.1:
 +```bash
 +sudo -u maas virsh -c qemu+ssh://ubuntu@192.168.122.1/system list --all
 +```
