* added ip alias for interfaces
* Update settings and improve vm performance
* Change the VG name in VMs. The VG name was changed so that the volume
which is being used by VMs can be mounted on a physical host, and not
conflict, with standard volume group naming. This is usful when a VM
is DOA and a deployer wants to disect the instance.
