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).
I wasn't sure about this. Don't you want EIP to point to the beginning
of the instruction such that the exception will cause the instruction to
restart?
