  I didn't suggest to install Michael Young's kernel. You may build directly via J.F. Git Repo:-

# yum install mercurial gitk
# git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
# cd *-xen
# git checkout origin/rebase/master -b  rebase/master
# copy ../config-work  .config
# make
# make modules_install install

Pvops kernel 2.6.31-rc6 should be built and installed on system.
Working .config is attached (x86_64). No need run "make menuconfig"

However, i got it working with both kernel. Stack trace in dmesg output
of fedora's kernel seems to be harmless.

Clean install with right sequence of steps seems to be important. I was unable reinstall system once been built. Try to follow blog's steps one by one. Point of kernel build doesn't matter.

I was just trying to get this combination setup up and running. I am on
Fedora 11 and mostly followed Boris Derzhavets' blog to get it done.

Sadly the box complains that it can not connect to the hypervisor when
starting libvirtd and also xend startup fails.

libvirtd screen message:
ERROR Internal error: Could not obtain handle on privileged command
interface (13 = Permission denied)
FATAL: Failed to open connection to hypervisor: Permission denied

In the kernel log I saw this:
[ INFO: SOFTIRQ-safe -> SOFTIRQ-unsafe lock order detected ]
2.6.31- #1

See dmesg at http://p.carnivore.it/MrGxdQ for more info.

Thanks for any hints or clarification!
