[PATCH] arm/hvf: panic the guest if an unhandled exception occurs in el1

Posted by Leesoo Ahn 1 month ago

It's better to clean up any resources that the guest taking and quit
if an exception in el1 could not be resolved.

Otherwise, the guest would get in the infinite-loop black-hole by
unmodified pc.
