HOW-TO Install Ganeti/Xen/DRBD ?

You need a Volum Group on your server (LVM) named "vgganeti" for store VMs.

apt-get update && apt-get dist-upgrade
apt-get install git vim aptitude sudo htop screen curl openssh-server locales
apt-get -y install xen-linux-system xen-tools
dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen
sed -i '/TOOLSTACK/s/=.*/=xl/' /etc/default/xen
echo 'GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=1024M,max:1024M \
  dom0_max_vcpus=1 dom0_vcpus_pin"' > /etc/default/grub

Add a VM in plain disk:

gnt-instance add plain --disk 0:size=20G --disk 1:size=200M \
-B memory=2G,vcpus=2 -o debootstrap+jessie --no-ip-check \ 
--no-name-check vm.domain.com

Add a VM in DRBD (fully-sharred between two servers) :

gnt-instance add drbd --disk 0:size=20G --disk 1:size=200M \
-B memory=2G,vcpus=2 -o debootstrap+jessie --no-ip-check \
