I guess you could have a loop
1: hlt
jmp 1b
and enter it programming a timer to something close, and examine the
vcpu state afterwards. However you don't propagate the VMCS halted
state to the corresponding kvm state, so there's no way to test it.
(a minor bug in your patch)
The activity state doesn't get propagated at all to the kvm state.
Can we get into a non-zero activity state today (either SHUTDOWN or
WAIT_SIPI)?
No, right now we intercept SHUTDOWN (and turn it back, in qemu, into a
RESET), and we emulate all the SIPI stuff. We also intercepted HLT so
we couldn't get that activity state either.
