"I think Xen is a great product. It is easy to use.
But most important is the very active
community around it.
I would not say many 'issues' around using
Xen, but 'challenges' are addressed there [in
the community] with the things every virtual
machine has to deal with. Things such as: I/O-
issues, guaranteed scheduling issues, domain
zero security concerns,…
The community out there is very helpful. That
was a very big reason for us in selecting Xen."
