available via "yum install" . Anyway Fedora's Libvirt has the best
compatibility with Xen 4.0.1.
It's not too late switch back to Xen with PVOPS kernel. XenLinux 2.6.34.7
aka Suse
is really dangerous . It outperforms pvops kernel about 15-20 % under Xen
4.0.1.
- How did you measure this performance difference?
- Did you make sure kernel configuration is similar for both kernel types?
Many pvops .configs have various debugging options enabled that kill the performance..

I don't mention KVM performance. It's not a competitor for
OpenSuse 11.3
after the
most recent "zypper update"

There is less urgency to test now because 4.0.1-6.fc14 has now made it
into F14 in time for the release. You can of course continue to test if
you want to.
