was expecting that by destroying the view in step 3, all the MFNs
in that view would revert back to XENMEM_access_default. However, after
completing step 4, I still encounter #VEs based on the permissions I set
in step 2.
Is this a deliberate design decision?
Thanks,
Matt

Andrew,
Thank you for the tip. The crash does not happen when the "maxmem"
option in the config file is disabled. I still get funny behavior with
my driver, but I need to investigate that further.
Regards,
Matt

happens immediately. I've also seen a delayed host crash
with Xen 4.6, but I'm focusing on the 4.8 RC here.
I don't know exactly which step causes the crash. I'll continue my
investigation today.
I'll work on a sample driver to exercise the crash if that's helpful.

in the xen code or through searches.
I am attempting to use the altp2m API from a domU and need to handle #VE.
