Hi
I wanted to mention that I have not found an issue on this in my regression testing running on this code against a PPA.
The qemu already in -unapproved is identical to what I proposed and we checked on - so lets keep it there as is to be accepted.

Bug description:
[impact]
this bug is to track re-uploading the fix for bug 1823458 plus a patch
to fix a regression it introduced.
instead of copying the details from bug 1823458, please see that bug
for impact and testcase.
[test case]
see bug 1823458 for the original bug test case
for the regression test case from bug 1829245, rebooting the guest
will result in the guest being unable to use the interface (possibly a
couple reboots are needed to reproduce if the interface still works
after the first reboot).
[regression potential]
see bug 1823458
additionally, the regression from the last fix is in bug 1829245.
the change is in code where this still has the regression potential of
causing guest networking to fail.
