by explicitly moving it out of the interrupt shadow. The hypervisor is done "executing" the HLT and by definition this moves the vcpu out of the 1-instruction interrupt shadow. Prior to this change the interrupt would be held pending because the VMCS guest-interruptibility-state would indicate that "blocking by STI" was in effect. This resulted in an unnecessary round trip into the guest before the pending interrupt could be injected. Reviewed by: grehan
