Sorry, it sounds funny. I just realize that KVM from RH,Canonical or whoever else
is not solution for enterprise at least in meantime.
CPU utilization numbers and real performance is horrible on testing boxes.
Jeremy,Konrad,Xiantao Zang,Yu Ke,... are pretty close. Even 2.6.31.13 is good.
Commitment of 2.6.32.X stable line with  Xiantao's  Zang APIC rework probably supposed to run under official Xen 4.1 would be the end of KVM/QEMU type_2 hypervisors  story. It doesn't matter will Xen Dom0 support merge mainline  Linux or no.
It's gonna be new XenServer.

Boris.

I am glad it helped!

Thanks for the tip. As far as Xenlinux kernel configs go, I am still hoping to try and compare Boris's 2.6.32 config against SLES 11 SP1 when it comes out.

As for pvops, I also found Pasi's config to work nicely too, after all debug option were turned off.

And as a side note for XEN 3.4.3 and pvops users, it seems like there is some compatibility issues there.

Thats probably because your a XEN professional by now. I have been running XEN for ~3 months now.
Really thanks for the config and for the wordpresses :)

The names mentioned above contribute a great deal, and I believe should also be recognized for all their efforts!
