Regarding root=/dev/cciss/c0p01 does it match "df -h" reported path to "/" .
If yes, i would try to build kernel with built-in static command line
root=/dev/cciss/c0p01 ro console=tty0 ( not to pass them via grub2 entry)
If no what reports "df -h" ?
What kernel to support Xen in Dom0 you try to build on Ubuntu 9.10 Server ?
Xen 3.4.3 setup with 2.6.31.9(8) xenified aka Suse kernel as well as 2.6.31.6 pvops kernel on Ubuntu 9.10 Server works for me on SATA drives:-

Hi all, I thought my cpu soft lockup issue were behind me with the addition of the sched-credit stuff. However I'm still experiencing the lockup issues when an domU does anything cpu intensive. A large tar will completely hang it. This has lead me to try to upgrade/change the kernels on my servers. I started by downloading the source from xen.org and compiling on my Ubuntu Xen dev server. This went surprisingly well. However when I put the new kernel in grub it will not boot as it can't find the root. I set root=/dev/cciss/c0p01 which should have worked. I tried by UUID, root=UUID=9da5323b-e47c-4367-bed0-2d2b53ba5a45 and still no joy. After six hours of every combo possible I gave up and threw a new set of drives in
the machine and installed Centos 5.2. The Centos install went fine and I installed the stock xen. I moved over a test domU and tried to add it with xm new. Of course the xen from the Centos distro is like 3.0 and doesn't even have the xm new option. So I try to start with xm create and I get the following error: ACMError: Policy file '/etc/xen/acm-security/policies/-security_policy.xml' not found. I did a few searches and see some work arounds/fixes but decide I'll try to build the latest as I did on Ubuntu. I've now done 7 builds only to have it fail every time an hour into it with some dependency that should have been installed. I did a yum groupinstall 'Development Tools' and verified that I had all the dependencies installed as stated in the README. It still amazes me that there is stuff missing (this last time it was makeinfo?). It's running yet again but I don't have high hopes that
it's going to complete without additional problems. I've now spent over two full days trying to get some stability with no luck. Is there any somewhat current (at least 3.3) yet stable 32 bit version of Xen out there with a simple installer? I know if I had 64 bit machines I could have easily used http://www.gitco.de/repo/ to update Centos. However new hardware right now is not an option. I'm open to any distro that is going to make this easier. At this point my frustration level is so high that I'm actually considering moving everything back to VMWare 3.5! Any ideas before I pull out the little hair remaining on my head?
