[Bug 1829245] Re: Networking issues after upgrade to 1:2.5+dfsg-5ubuntu10.37

[Dan Streetman]

@sw0x2a thanks - my patch (that breaks things) will be reverted in a new
release through the security pocket and i'll reapply the fixed version
thru the normal sru process.

Bug description:
  Since yesterdays upgrade to qemu packages version 1:2.5+dfsg-
  5ubuntu10.37, new VMs have networking issues. Their network interfaces
  stop working after a short time, are not even able to PXE boot but
  when, they will LOSE connectivity after a few seconds (longest was
  around a minute). Downgrading to 1:2.5+dfsg-5ubuntu10.36 fixed the
  issue again.

  Unfortunately there are no error messages thrown. This is all I can
  provide:
