[Bug 1650067] Re: qemu core dumps when unable to allocate ram for new virtual machine

[Dave Chiluk]

I have already tested the kilo version of this patch.  I basically
verified that booting a machine with too much allocated ram will not
cause a core dump.

I will work through getting liberty tested shortly.

  qemu core dumps when unable to allocate ram for new virtual machine

Bug description:
  Qemu available in the kilo-staging cloud archive will cause an abort
  which will generate a core dump, if there is not enough memory
  available to satisfy creation of the new Virtual Machine.

  This becomes more critical if this happens over and over in highly
  resource constrained environments, as the core dumps start filling up
  the disk.

  This is resolved with upstream commit
  f8ed85ac992c48814d916d5df4d44f9a971c5de4

  I'm opening this case, while I decide if it's worthwhile to re-spin
  qemu to fix this issue.
