Hi,
I've encountered a situation in which I would like to allow userspace
to set the MSRs which KVM should not emulate and instead implement
these as no-ops.
I have not seen any work in this space, furthermore there is an item
on the KVM TODO that is very similar to what I'm trying to do.
The userspace interface is an extension of kvm_vcpu_ioctl, adding the
KVM_SET_MSRS_NOOP flag. It takes a struct kvm_msrs as a list of which
MSRs should be no-ops and adds the field noop to struct kvm_msr_entry.
This patch only affects vmx, but if the approach is sane, I can
extend it to support svm as well.
Does the ignore_msrs kvm.ko parameter achieve what you want?
Ah, I forgot all about that.
