This should be fixed in Karmic's qemu-kvm-0.11. Please reopen if you can reproduce this issue with that package. :-Dustin ** Changed in: kvm (Ubuntu) Status: New => Fix Released -- Block I/O crashes after migration https://bugs.launchpad.net/bugs/341682 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Author: Glauber Costa Date: Mon Jul 6 09:32:09 2009 -0400 flush pending aio requests When we finish migration, there may be pending async io requests in flight. If we don't flush it before stage3 starting, it might be the case that the guest loses it.

Thanks a lot for the bug report, and the workaround. I'll try to get a setup where I can test this, and confirm it. :-Dustin -- Block I/O crashes after migration https://bugs.launchpad.net/bugs/341682 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 341682] Re: Block I/O crashes after migration
I found a workaround to this problem. Before starting migration, stop guest (from qemu monitor) and wait 1 second, and cont after migration. This is not quite "live" migration, but guest kernel happily continues running even under heavy I/O load. This works for both ide and virtio. -- Block I/O crashes after migration https://bugs.launchpad.net/bugs/341682 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
