   4 Subject: [PATCH] PVE: monitor: disable oob capability
   5
   6 A bisect revealed that commit 8258292e18c3
   7 ("monitor: Remove "x-oob", offer capability "oob" unconditionally")
   8 causes unexpected hangs when restoring live snapshots from some
   9 types of block devices (particularly RBD).
  10 We need to figure out what's happnening there. For now, since we
  11 had this disabled before and probably don't need it now either,
  12 disable oob, so we can get a functioning qemu out...
