Subject: [PATCH] KVM: x86: list MSR_IA32_UCODE_REV as an emulated MSR
Date: Tue, 21 Jan 2020 14:48:05 +0100 [thread overview]
Message-ID: <1579614487-44583-1-git-send-email-pbonzini@redhat.com> (raw)
Even if it's read-only, it can still be written to by userspace. Let
them know by adding it to KVM_GET_MSR_INDEX_LIST.
