It's more than digging in some manuals.  The last two Xen deployments we
worked on we abandoned before going into production, after spending weeks
of work on them.  The last absolutely successful Xen deployment I had was
the version 2 code 5 years ago.

Reading the manuals is a given.

But expecting to take a current, existing system, and just drop Xen on it
is, in my experience, unlikely to work out for you.

Correct, it's not in the repositories.  It's commercial software, that just
happens to be free.  As far as there being lots of add-ons you have to buy
down the road, you're thinking of VMWare ESX, which is the bare-metal
version (which also works great, but you can't just drop on an existing
system), or more specifically their "vCenter" line of products which ESX
forms the base.

No idea.

I mostly use ESXi, but once we get this new server down to the data center
and I get some time, I want to play with Proxmox.  KVM I've used on my
laptop in the rare occasions where I've wanted a virtual machine but not at
our data center.  VMWare server we have several clients using.  For my
Nephew to try Linux on his Windows machine, I used VirtualBox.  That's not
really from what I can tell a server-oriented system though.
