Have not noticed any particular problems.
What is it?
What can be done?
Then next one may not be xen but I only had the problem after running a domu.
After a while I get kernel error and networking stops.
This is the error:

Kernel logging (proc) stopped.
In this case dom0 locked up. Some times just networking stops and some times
networking recovers.
I downloaded new igb driver source from Intel and installed it.
It's running OK so far but it has not been long enough to tell.
Any ideas?
John
