[Bug 524447] Re: virsh save is very slow
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
[Bug 524447] Re: virsh save is very slow
Tested 0.12.3+noroms-0ubuntu9.14 on Lucid amd64 with all available updates. Save speed is now approx 3 seconds for a 256Mb guest. Tested virsh with start, stop, save, restore, suspend, resume, shutdown, destroy. Tested guest with smp, virtio disk, virtio net, vnc display. Everything worked as expected. If there's more I can do, let me know.

[Bug 524447] Re: virsh save is very slow
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. I checked for basic functionality with the packages you provided and the basics seem to work, (virsh start, stop, restore, save. Guest disk, net, vnc) but I didn't do much more. How deep should I go testing for regressions? -- 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
[Bug 524447] Re: virsh save is very slow
I'd like to help get this fixed, particularly in Lucid. What can I do? Does #21 and #22 still need testing? -- 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
