He means disabling kerberos authentication in your SSH client config, whether it be globally in /etc/ssh/ssh_config or ~/.ssh/config, assuming you're using qemu+ssh:// to migrate your VMs. Either way, this does not work for me. I can reproduce this error with: # virsh migrate --live --verbose --persistent --copy-storage-all vm1 qemu+ssh://aa...@kvm1.example.com/system -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/988291 Title: virsh -c qemu+ssh://root@source/system migrate --domain client --desturi qemu+ssh://root@destination/system fails Status in QEMU: New Status in “libvirt” package in Ubuntu: Confirmed Status in “qemu-kvm” package in Ubuntu: Confirmed Bug description: After upgrading from Ubuntu 11.10 to 12.04 migrating a VM from a not migrated host (Ubuntu 11.10) to a migrated host (Ubuntu 12.04) fails: Only error message found: qemuMigrationUpdateJobStatus:890 : operation failed: migration job: unexpectedly failed Ubuntu 11.10 uses: libvirt-bin 0.9.2 Ubuntu 12.04 uses: libvirt-bin 0.9.8 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: libvirt-bin 0.9.8-2ubuntu17 Uname: Linux 3.2.16 x86_64 ApportVersion: 2.0.1-0ubuntu5 Architecture: amd64 Date: Wed Apr 25 14:12:29 2012 InstallationMedia: Ubuntu-Server 10.10 "Maverick Meerkat" - Release amd64 (20101007) ProcEnviron: TERM=screen-bce SHELL=/bin/bash PATH=(custom, user) LANG=de_DE.UTF-8 SourcePackage: libvirt UpgradeStatus: Upgraded to precise on 2012-04-25 (0 days ago) mtime.conffile..etc.apparmor.d.usr.lib.libvirt.virt.aa.helper: 2012-04-25T12:40:42.878700 mtime.conffile..etc.default.libvirt.bin: 2011-01-25T16:19:29.769778 mtime.conffile..etc.libvirt.libvirtd.conf: 2012-04-25T13:57:06.138857 mtime.conffile..etc.libvirt.lxc.conf: 2011-01-25T16:11:34.670971 mtime.conffile..etc.libvirt.qemu.conf: 2012-04-25T12:18:38.835193 mtime.conffile..etc.sasl2.libvirt.conf: 2011-01-26T17:57:01 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/988291/+subscriptions
