[Xen-users] Re: XEN 4.0.1 and Linux 3.0?

[Eric Olsen <ericjolsen@xxxxxxxxx>]

This is my test platform running on slackware 1337 with xen 4.1.1 and
linux 3 rc3.

I have not had any stability or performance problems.  Running SBS
2011 and several guest linux hosts.  All HVM backed by dm-crypt lvms.
