** Description changed: [Impact]  * There are situations where disk I/O from guests to host scsi    devices can fail to return the right status. In doing so    the guest believes that I/O was successful while it was not    leading silently to latter data corruption.  * Upstream

I've accepted this, and I agree that this is a good candidate for testing in proposed for longer than 7 days; I'll do so after at least 14 days, so double the normal soak time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

Hello bugproxy, or anyone else affected, Accepted qemu into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/qemu/1:4.2-3ubuntu6.22 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See

Following up on some older bugs... Okay, that means the PPA version of qemu for focal could be successfully verified (no miss-compares). So I'll change the status back to In Progress ... ** Changed in: qemu (Ubuntu Focal) Status: Incomplete => In Progress -- You received this bug

Thanks Vanessa for the testing on the PPA! @Halil - I'd leave the debugging of the remaining issue to you as while you can't reproduce it yet it still is much closer to you than it is to me :-/ Thanks in advance, let us know what you find. In the meantime I have prepared the SRU content and got

You are right for a general stance of SRU minimality But this case felt like fixing 7/8 of a single whole. And while indeed your case didn't need this one more fix someone else would and we touch this code anyway. Vice versa all tests since this is upstream is done with it applied - so the

I'm done reading and while a complex subsystem and a bunch of changes they individually all seem sane to me (although a108557b could have side effects that are hard to spot). For SRU considerations I think this includes potential change of behavior of formerly silently ignored errors now becoming

I can confirm that just on the patch-level only two need backporting, the rest applies as is and I have regenerated them to match the packaging requirements. The backport-adaptations themselves are minimal. From the content I guess it is complex enough that nobody can be fully sure. I'm still
