Please see attachments for disk details and guest xml. FYI, I was able to migrate successfully another guest lotg1 which uses raw type disk image with 'copy-storage-all'. For lotg2 it has qcow2 images. Both lotg1 and lotg2 have their disks in same place - XFS filesystem : /lotg1_2_disks - Krishnaja -- 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
