## Install libvirt (1.2.0), and enable VM (KVM/Qemu) live
|
||||
## migration. Default libvirt on Ubuntu 12.04 is 0.9.8, which does not
|
||||
## work well with Open vSwitch ("<virtualport type='openvswitch'/>"
|
||||
## cannot be added into VM xml configuration).

||||

# Install KVM, QEMU and libvirt (0.9.8, so that we have /etc/init/libvirt-bin.conf)

# if you don’t want ESX support.
