You need to set up a serial console so you can capture the boot messages:

You can't really use the "xenlinux"
kernel-2.6.27.42-0.1.1.xs0.1.1.737.1065-i686-xen.config
with a pvops dom0 kernel. They're different kernels with different .config
options.

Set up the serial console and figure out why xen/next pvops dom0 kernel doesn't
boot for you.
Make sure you have these options for the dom0 kernel:
console=hvc0 earlyprintk=xen nomodeset
