I'm going to ask you almost the same questions as on centos-list..

Nope, no such experience with many xen hosts.

How do you measure this "IO load" ? What effects does it have?

What kind of hardware do you have (cpu/mem/nic/disk or raid
controller/disks)?

Are you running centos5? latest updates installed? or fedora? what fedora
version? what kernels? 

Can you post any performance data? How does this "io load" make domU
unusable? 

I'm sorry byt your problem description lacks a lot of important
information..
