Re: [libvirt] [PATCH v2 3/3] KVM: VMX: enable guest access to LMCE related MSRs

Thanks for the explanation! If we disable LMCE in QEMU by default (even for -cpu host), will it still be a problem? That is, - pc-2.7 can continue to run on old kernels unless users explicitly require LMCE - existing libvirt VM configurations can continue to work on pc-2.7 because LMCE is not specified in those configurations and are disabled by default (i.e. no requirement for new kernels) - existing QEMU configurations/scripts using pc alias can continue to work on pc-27 for the same reason above.
