I looked at one patch that used the kernel timer. It was based on a
1000hz timer. I have seen vendor-hosted xen kernels with that value
changed to 100 hz or 250 hz. If you use any type of outsourced xen VM,
be sure to ask the vendor about this. Also be sure they provide the
appropriate include files for their kernel build. That will allow you to
build/install kernel modules on your VM.

There are a lot of other things that might be changed in a vendor xen
configuration. I have some things here on my own xen hosts that run
fine. They don't run so well on outsourced VM's I have tried.
