RE: [Xen-devel] Re: windows bluescreen after restore



IRQL_NOT_LESS_OR_EQUAL happens when a kernel thread with high priority tries to 
access a virtual address which is paged to the disk (since the paging mechanism 
in windows runs in a lower priority of the thread). Most of the chances that 
this is around paging...

If you can reproduce the bug and it happens any time that you do save/restore, 
I would suggest to try to tun the guest with paging disabled (System Properties 
-> Advanced -> Performace [Settings] -> Advanced -> Virtual Memory [Change] -> 
Select "No paging file") and then try to do save&resote.

STOP 0x8E is KERNEL_MODE_EXCEPTION_NOT_HANDLED and could be a side effect...

Thanks,
Guy.
