This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Thanks for the detailed report Benjamin. The old style qemu block migration that virsh --copy-storage-all invokes is known to be pretty inefficient, though your description sounds much worse than my understanding. In F19, libvirt will be using new qemu functionality to implement --copy-storage-all in a much more performant manner: https://fedoraproject.org/wiki/Features/Virt_Storage_Migration However F16 is going unsupported now, and qemu has changed a lot since then. If you can still reproduce on F18, please reopen this bug. Though I'll probably just move it to the upstream tracker since it's unlikely to be fixed in Fedora |
