The current implement doesn't clear which access type we support for APIC-Access VM Exit: 1) linear access for an instruction fetch -- APIC-access page is mapped as UC which doesn't support fetch 2) linear access (read or write) during event delivery -- Which is not happened in normal case except the guest went wrong, such as, set the IDT table in APIC-access page. In this case, we don't need to support. 3) guest-physical access during event delivery; guest-physical access for an instruction fetch or during instruction execution -- Do we plan to support enable APIC in real mode ? I don't think so. Tracked-On: #1842 Signed-off-by: Li, Fei1 <fei1.li@intel.com> Acked-by: Anthony Xu <anthony.xu@intel.com>
