I tested that other bug. As far as I can tell it is not fixed. I haven't gotten any sort of response on it for a week.

Ok so I spent a while at this and it does not appear to be fixed to me. I'm not really familiar with release upgrades so it might just be my unfamiliarity, if so someone with more understanding of what is going on will need to verify this instead. Here's what I did. I installed hardy server amd64, upgraded it, installed qemu and kvm and made a snapshot of it. From there I tried several different things, rolling back each time. 1) do-release-upgrade. Worked fine, resulting system had qemu and kvm related packages installed normally. I did see the error below in the log. This is the recommended way to do a release upgrade as far as I understand it, so probably why this was not caught before now is that it is just a warning in the log but the resulting system is fine. Unpacking qemu-common (from .../qemu-common_0.12.3+noroms-0ubuntu9.17_all.deb) ... dpkg: warning: overriding problem because --force enabled: trying to overwrite '/etc/qemu-ifup', which is also in package qemu 0:0.12.3+noroms-0ubuntu9.17 2) add lucid-proposed to apt sources, pinned proposed/* at 400, proposed/qemu,qemu-common,qemu-kvm,kvm at 600, do-release-upgrade.

The page you referenced doesn't include anything that I can find about the ticket priority level. It states that Stable release updates will, in general, only be issued in order to fix high-impact bugs and provides several examples. Among them is Bugs which do not fit under above categories, [security vulnerabilities, severe regressions, or loss of user data] but (1) have an obviously safe patch and (2) affect an application rather than critical infrastructure packages (like X.org or the kernel). I submit that this is an obviously safe patch. The change is small, simple, isolated, has been tested to work, and doesn't change any interfaces. Is qemu-kvm considered a critical infrastructure package or not? I don't know the answer to that, but I can see valid arguments both for and against. I also have an example of a potential data loss situation, though it is admittedly somewhat weak. I'll spare everyone the narrative but I'll share it if it would be helpful. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/524447 Title: virsh save is very slow To manage notifications about this bug go to: https://bugs.launchpad.net/libvirt/+bug/524447/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Ok, great! Thanks for the quick response. I did just now get finished testing the packages you attached in #21 using my lucid box. Saves of a 256Mb guest went from ~50 seconds to ~3. So it does seem to fix the issue. I can set up a Maverick box if you need it tested there as well.
