hlt exiting doesn't leave vcpu in the halted state (since hlt has not

Right, you mean the guest activity state being halt.
My understanding is that it just needs to be cleared on exception
injection. Would could clear it at every vmentry but that would
introduce a vmcs_read() to the fast path which is undesirable.
Also need to skip the hlt instruction (by calling the emulator for example).
