we have successfully tried to run both xenified and pv_ops 2.6.30
kernels for DomU.

How would you describe the main difference between those two approaches?

What is the main difference?
Are the possibilities the same?
What about speed?

Our needs for domu are pretty low - some CPU, some RAM, lvm HDD, 1-3
virtual NICs. That's all.
Nothing like PCI/USB passtrough - just plain VPS linux machine.

Differences from our point of view:

1) pv_ops can be used even with latest 2.6.31-rcX kernels
2) xenified kernel currently with only
3) in XM TOP idling VPS with xenified kernel is really not consuming
CPU(secs) while
    VPS with pv_ops kernel is always using like 1-3% of CPU even when
guest OS idle.

Thanks for your opinion
