This wishlist bug has been open a year without any activity. I'm going
to move it to "Opinion / Wishlist", which is an easily-obtainable queue
of older requests that have come on. This bug can be reopened (set back
to "New") if someone decides to work on this.

Title:
  affinity server group is limited on one host

Status in OpenStack Compute (nova):
  Opinion

Bug description:
  In OpenStack Configuration Reference section scheduling, it states following:
  Are in a set of group hosts (if requested) (ServerGroupAffinityFilter).

  It looks like affinity server group can be placed on multiple hosts,
  but after some trials and investigation, the affinity server group is
  limited on one host. When the current host doesn't have enough
  resource to host the subsequent VMs, the nova scheduler returns "No
  Valid Host Was Found".

  I don't exactly know whether one affinity server group plans to
  support multiple hosts. If yes the current implementation needs to
  update. Otherwise, above document needs to reword.
