Thanks alot for the useful information. I will give it a try what is suggested.
Kindly tell me one more thing. I dont found "xenbr0" interface while running "ifconfig -a" command in "dom0". It doesn't come with xen3.4.2 and FC11 pv os kernel 2.6.30-rc6-tip or there's some problem here on my side?

Regards,
Fasiha Ashraf

Building dom0 kernel with 1000hz the rate reach 1k. Ok, one point. Then?
Why this behaviour occurs only on xenolinux?
