Re: [PATCH RFC] i386/kvm: fix enlightened VMCS with fine-grained VMX feature enablement

SECONDARY_EXEC_VIRTUALIZE_APIC_ACCESSES

the problem with it is that we don't have 'apic_access_addr' field in
eVMCS ('virtual_apic_page_addr' is there). By running the same setup
with eVMCS disabled I figured out which address can be hardcoded to make it boot.

Maybe it's really hard coded (what is the value? Is it consistent across Hyper-V version?) Can you try changing KVM to enable it and see if the hardcoded APIC access address works?
