Public bug reported:
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:
