Hi Aryeh, > bhyve does not send a shutdown signal to guest OS's and wait from them > to halt.... This requires a couple of things - an ACPI event channel in bhyve to inform the guest of events, and a way to signal bhyve to raise these events e.g. a simulated power-button press. On the TODO list. > this is despite having -H on the command line Ah, so that's different: the -H option signals the VT-x hardware that it should exit when the guest issues a HALT instruction. This is then used by bhyve as an indication that the guest vCPU is in an idle state and can be put to sleep until an async event arrives. later, Peter.
