Hello Rafael, or anyone else affected,
Accepted qemu into xenial-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/qemu/1:2.5+dfsg-
5ubuntu10.40 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See
While the issue fixed is purely cosmetic we have had users led astray by these
in the past.
Since we do an SRU anyway that should be ok to be uploaded.
Further I wanted to mention that I have not found an issue on this in my
regression testing, yet I had no AMD host which the change is targeted
There are 2 things in this bug:
- I had changed kernel to hwe-edge in Xenial during my tests and haven't
realized that the nested kvm would only work with hwe-edge kernel
(despite the requested feature CPUID warnings).
- The warnings are, indeed, fixed by the SRU proposed patch, but they
are

Hey Christian,
sorry for missing the SRU template, I was in hurry to create a package
for myself and some local needs. I'll do it right now, feel free to SRU
it whenever is good for you based on other fixes I know you usually take
care off.
Thanks a lot!

Thanks Rafael for identifying the issue and already providing a patch.
A few other things need to clear the SRU pipe first, then we can take the
change it LGTM.
Would you - in the meantime - find the time to add a full SRU template
[1] for this to the description already?
