I'm no expert at centos, but since a while the areca driver has found it's

I can't remember any distribution shipping a kernel without it.

I would recommend you to check your dom0's initrd.img and eventually rebuild
it, as I assume the areca driver is build as a module.

That is strange, i am installing centos5 from dvd image downloaded from centos site. The default install with all updates doesn't recognize the areca card at all. The main problem is my /root also recides on the raid, so if the driver is not loaded i get a kernel panic.

btw. If your dom0 kernel doesn't support the raidcontroller, you're in no
case forced to recompile your whole xen. Just pick a recent, xen-enabled
distro kernel from a distro you like. My favorite is the 2.6.22-14-xen out of
the ubuntu gutsy repo, but your mileage may vary.

Thanks, but i already compiled xen on centos. Now the main problem i am facing is how to boot the existing domU.
