HV APIC(i.e., synthetic APIC controller exposed by Microsoft Hypervisor)
does not support one-shot operation using a TSC deadline value. Due to
which we see the following backtrace inside the guest when running with
hypervisor-fw/OVMF:
[ 0.560765] unchecked MSR access error: WRMSR to 0x832 (tried to
write 0x00000000000400ec) at rIP: 0xffffffff8f473594

Also, if this feature is exposed guest would not finish booting and get
stuck right before unpacking the root filesystem.
