Hi Krishnaja. thanks for testing and your report! I just checked my regular tests that run over and over and none shows the issue, but looking deeper I think I need to integrate part of your setup into my cases.
The error as reported is around qemus nbd code, so I compared why this can happen in your but not my usual cases. I'd assume that is due to --copy-storage-all in your case which I did not use so far. I wanted to extend the tests anyway, this might become the bug that forces me to do so. >From the man page we learn what the most important info should be: --copy-storage-all indicates migration with non-shared storage with full disk copy [...] the disk images have to exist on destination host, the --copy-storage-... options only tell libvirt to transfer data from the images on source host to the images found at the same place on the destination host. By default only non-shared non-readonly images are transferred. I think I saw BTRFS and many disks in the logs, but not all might be needed. There are e.g. many ways to prep the target image/paths like in [1],[2] or otherwise. So to best recreate your case I wanted to ask if you could provide the following: - paths of your guest image file(s) on source - paths of your guest image file(s) on target - filesystem/storage setup of the paths those files are in - Guest XML of the guest you are migrating (to check how many and which mode disks it has defined) [1]: http://hgj.hu/live-migrating-a-virtual-machine-with-libvirt-without-a-shared-storage/ [2]: https://www.redhat.com/archives/virt-tools-list/2012-February/msg00057.html ** Changed in: qemu (Ubuntu) Assignee: Taco Screen team (taco-screen-team) => ChristianEhrhardt (paelzer) ** Changed in: qemu (Ubuntu) Status: New => Incomplete ** Summary changed: - Ubuntu17.04 KVM: Non-shared migration internal error: client socket is closed; virsh commands hang at destination + Ubuntu17.04 KVM: Non-shared migration: nbd_receive_request():L710: read failed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1680162 Title: Ubuntu17.04 KVM: Non-shared migration: nbd_receive_request():L710: read failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1680162/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
