Looking back at the HEAD from a few commits ago, it's obvious that
using the LDFLAGS variable for linking the guest_init binary was

Hi Paolo,
May I ask that any suggestion about the version 2 of VMX LBRV?
This version is updated following your advices in version 1.
BTW the kvm-unit-test for this feature has sent too, and I
have tested the CPUs emulated by QEMU.
Thanks,
Jian
