Hi All,

Will Xen 4.0 release use the pv-ops kernel, despite the fact that it
has about ~15% hit in performance?
This is a major performance hit, and releasing a new Xen version with
a 15% performance hit in the dom0 kernel compared to a previous
version, will just cause people not to upgrade to Xen 4.0 (especially
if Xen 4.0, won't support the old 2.6.18 xen kernel anymore).

Is this performance issue going to be addressed prior to Xen 4.0 release?

Tom
