Currently I've got 3 kvm servers: 2 servers with local LVM storage
pools, and 1 server with a storage pool (still) on a local file system.
Each kvm server has 2 quadcore CPUs, plenty of RAM and disk space.
In addition there is a storage pool on an NFS server.

The plan is to have domains for nightly builds and tests, to be cloned
on demand from a set of template domain and configured via dhcp. The pool
for the templates should be shared between all servers; the on-demand
clones should be kept on a local pool on one of the kvm servers.

Other domains are supposed to provide "static" services, e.g. a Wiki,
EMail, or some groupware. They should be created and configured once,
but for backup they should be cloned to the NFS pool, too. It is
important that these services can be recreated in a short time if one
of the kvm server dies.

- From my side it is sufficient if each domain is bound to a single
storage pool.

Harri
