Hi,
dfor 19.04 it should be fixed once we merged qemu 3.1 which is the current plan, but for SRUs I'm not so sure.
The backport isn't hard at all, but removing a warning is certainly not worth an SRU cycle and dropping an update of qemu to everybody out there.

How about keeping it open for now and bundling it with whatever the next SRU will be?
Would that be ok for you?

FYI - the fix for this bug as an SRUs is ready and testable from a PPA for
Cosmic [1] and Bionic [2].

I'm gonna check the test instructions myself by testing that from the PPA before uploading to the SRU queue.

In addition I'll push these PPAs through the automated regression tests for qemu/libvirt.

I tested the SRU testcase
1. it triggers as expected
2. the builds from the PPA fix it as expected

That said this would be ready to go to the SRU queue, but there are other bundled cases that I need to test first.

Hello bugproxy, or anyone else affected,

Accepted qemu into cosmic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/qemu/1:2.12+dfsg-3ubuntu8.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-cosmic to verification-done-cosmic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-cosmic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Hello bugproxy, or anyone else affected,

Accepted qemu into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/qemu/1:2.11+dfsg-1ubuntu7.10 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Tested with the config described in the bug:
System page size 0x40000000 is not enabled in page_size_mask (0x11000). Performance may be slow

Updated to proposed and restarted the same guest, no such message in /var/log/libvirt/qemu/b-huge.log where you'd usually see it.

Therefore setting verified.

@SRU Team - I beg your pardon and wanted to make clear that I try to care for my SRUs.
This looks all good except autopkgtest failing for other reasons.
Those are handled in bug 1817721.
IMHO: Feel free to release this as-is and/or to help getting the MP associated to 1817721 accepted.
