The easy way you migrate a running from one host to another VM is have the image on an NFS mounted on both hosts. The hard way involves copying the actual image file, however, if you use ZFS you may get away with only copying a small incremental snapshot. Last but not least, you can set it up on DRBD and make sure you get your HA stack set up to migrate everything over correctly. With all the network-controlled power outlets and the rest of the bloat you need to make corosync/pacemaker run. Personally I believe in simple stupid; all my VMs live behind door number 1. -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
