I get crashes with Win10 in kvm

Did you get the crash reliably?
I've been struggling how to trigger it efficiently, but currently in
vain.  The memory pressure isn't a single key to trigger it, as it

Yes, I get the crash pretty reliable with Win10 in kvm after 10 to 30 minutes. 
Some workload in Windows seems to be necessary to trigger the bug.
