without starting vm, we did decompression stress test. harddisk offline did not happen. when some vms are running, we did decompression stress test. harddisk offline happened frequently.

we have just upgraded to xen4.0+kernel2.6.31.13. however, we fonud that disk offline in high disk IO(xen4.0+kernel2.6.31.13). but whitout xen4.0, we only start with kernel2.6.31.13, the disk offline didn''t happen. I think it is a bug. test case: 57 physical machine we start 5 vm(cpu:2, memory:1024) in a physical machine.at the same time we do decompression in dom0. tar xzvf *.tar.gz tar
