Hi Kent,

I'm going to try and reproduce it myself as well. I just used IOMeter in a
Windows DomU with 30 workers, each having an io depth of 256. A *very*
heavy workload indeed, but my point was to see if I could break something.
Unless the issue is specific to windows causing problems (NTFS or whatever),
I'm guessing running fio with 30 jobs and an iodepth of 256 would probably
produce a similar load.

BTW, do you have access to a Xen node for testing?

Does the problem resolve itself after you shut down the windows DomU? Or only when you reboot the whole Dom0?
