Subject: [PATCH 6/11] KVM: Fix mmu going crazy of guest sets cr0.wp == 0
Date: Tue, 30 Jan 2007 14:42:00 -0000 [thread overview]
Message-ID: <20070130144200.2955FA0014@il.qumranet.com> (raw)
In-Reply-To: <45BF57C9.7000103-atKUWr5tajBWk0Htik3J/w@public.gmane.org>
The kvm mmu relies on cr0.wp being set even if the guest does not set it. The
vmx code correctly forces cr0.wp at all times, the svm code does not, so it
can't boot solaris without this patch.
