I have followed Boris' guide at: http://bderzhavets.wordpress.com/2009/02/17/setup-xen-unstable-dom0-via-2629-rc5-pv_ops-enabled-kernel-on-intel-sataahci/ and after I reboot into the new rc5 kernel and try to start xend, I am getting this error:

xend start
ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)

    xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')

The only thing I think might be wrong is I did it in the wrong order. Would installing the kernel first then Xen be an issue?

It looks like you need to add

xenfs            /proc/xen        xenfs    defaults    0 0

to your /etc/fstab.
