by adding an argument to the VM_SUSPEND ioctl that specifies how the virtual machine should be suspended, viz. VM_SUSPEND_RESET or VM_SUSPEND_POWEROFF. The disposition of VM_SUSPEND is also made available to the exit handler via the 'u.suspended' member of 'struct vm_exit'. This capability is exposed via the '--force-reset' and '--force-poweroff' arguments to /usr/sbin/bhyvectl. Discussed with: grehan@
