[PLUG] New Server Virtualization

I work on Openstack at work and I can tell you it is a very large and
complex suite of software.  Which makes it very hard to set up and
configure and makes it less than desirable for home use.  However you might
want to use it at home if you want to get experience working with it, are
interested in being able to build tooling to deploy vms using either EC2 or
Openstack Nova apis that cloud providers use or you want to use some of the
more advanced functionality such as virtualized networking, support for
802.11q vlan tagged networks, integration with ceph/gluster distributed
filesystems, object storage,, etc.  Generally I'd say it's overkill for
most home use though.

If you only want to run Linux and don't require the ability to run kernel
modules you might want to look at container technologies like docker and
coreos.  If you need VMs and want replication you could look at ganeti.
