Subject: KVM Page Fault Question
Date: Thu, 18 Mar 2010 19:50:02 -0400 [thread overview]
Message-ID: <4BA2BC2A.8090803@csail.mit.edu> (raw)
In-Reply-To: <4B9B5225.2050604@redhat.com>
When using VMX without EPT, is it ever possible for a guest to receive a
page fault without it first appearing (and being reinjected) in KVM?
I'm seeing some strange behavior where accesses to mprotected (but yet
to be accessed) memory causes a fault in the guest OS, that I cannot see
KVM intercepting.
Thanks!
Marek
