In my experience, Xen is stable, but only if it gets along with its host
and guest OS. Certain combinations just do not play nicely with Xen, at
least according to my own personal experience.
When you guys create VM servers, do you separate your user data from
your OS/application data by putting these on separate (virtual) disks? I
like to do this so that my VM image is as small as possible and easy to
replicate without having to manually delete irrelevant user data, but I
know that simply cloning physical hardware into a VM is a popular
approach to bringing up VMs as well...
