I used to have a lab with two Dell R200 servers, and I did not use
virt-manager because it was too easy to mess up.

Instead I used ProxmoxVE. Http://over.proxmox.com.  It is like VM Ware ESX,
except open source.  It uses OpenVZ for hyper virtualization a.d KVN/QEMU
for full virtualization.  It supports clustering, and has a drop dead
simple web console that would have made your life easier.

Hope this helps.
