Subject: [PATCH] KVM: nVMX: don't reset kvm mmu twice
Date: Sun, 12 Mar 2017 00:53:52 -0800 [thread overview]
Message-ID: <1489308832-29078-1-git-send-email-wanpeng.li@hotmail.com> (raw)
From: Wanpeng Li <wanpeng.li@hotmail.com>
kvm mmu is reset once successfully loading CR3 as part of emulating vmentry
in nested_vmx_load_cr3(). We should not reset kvm mmu twice.
