  Hi Anthony,

  Thank you for your comment.

  Is this comment about vmx_send_assist_req() ?

  So, it sets _VCPUF_blocked_in_xen flags before the code to use
do_yield. Thus, the VTi domain will be blocked until clear flags
via new xen-evtchn notification, I think.

** cf. evtchn_send() in xen/common/event_channel.c
