Subject: [PATCH 5/9] KVM: Don't set guest cr3 from vmx_vcpu_setup()
Date: Fri, 05 Jan 2007 07:54:45 -0000 [thread overview]
Message-ID: <20070105075445.722EE250048@il.qumranet.com> (raw)
In-Reply-To: <459E02E7.5020407-atKUWr5tajBWk0Htik3J/w@public.gmane.org>
It overwrites the right cr3 set from mmu setup. Happens only with the test harness.
