[ale] Hypervisors and such

[Jim Kinney]

Ovirt on centos - connection issues between manager and all VMs, not os specific. Most of my VMs are also centos. 10Gbps network, gluster storage for replication x3, semi-periodic connection issues still in troubleshooting mode.

Virt-manager rocks for a single host or very small number of hosts. Found I could run it on my laptop and connect to and manage VMs on my home server (i.e., ale).
