[PATCH 0/2] make -M memory-backend and -numa memdev mutually exclusive

Posted by Igor Mammedov 5 years, 9 months ago

The options can't be used together (1st provides RAM for non-numa and fake-numa,
while 2nd provides RAM for each numa node).
If used together it might lead to crashes, so add a check to prevent simultaneous
usage.

Igor Mammedov (2):
  vl.c: run preconfig loop before creating default RAM backend
  numa: prevent usage of -M memory-backend and -numa memdev at the same
    time
