It seems I have a similar problem but in the opposite direction of migration I have 3 nodes, two with 6.1 version + some updates (but below 6.2) and one with 6.2. I have a vm on 6.1 hypervisor and I'm able to live migrate it to the 6.2 host, but then I am not able to migrate from 6.2 to either one of the 6.1.... relevant components: 6.1 hosts qemu-kvm-0.12.1.2-2.160.el6_1.8.x86_64 libvirt-0.8.7-18.el6_1.1.x86_64 kernel-2.6.32-131.17.1.el6.x86_64 6.2 hosts qemu-kvm-0.12.1.2-2.209.el6_2.1.x86_64 libvirt-0.9.4-23.el6_2.1.x86_64 kernel-2.6.32-220.2.1.el6.x86_64 guest is named dacsmaster and it is rh el 5.4 the migration from 6.2 to 6.1 fails with # clusvcadm -M vm:dacsmaster -m intrarhev2 Trying to migrate vm:dacsmaster to intrarhev2...Failed; service running on original owner /var/log/messages information: on source hypervisor: Jan 12 15:45:17 rhev1 rgmanager[9267]: Migrating vm:dacsmaster to intrarhev2 Jan 12 15:45:18 rhev1 rgmanager[22193]: [vm] Migrate dacsmaster to intrarhev2 failed: Jan 12 15:45:18 rhev1 rgmanager[22215]: [vm] error: internal error missing hostuuid element in migration data Jan 12 15:45:18 rhev1 rgmanager[9267]: migrate on vm "dacsmaster" returned 150 (unspecified) Jan 12 15:45:18 rhev1 rgmanager[9267]: Migration of vm:dacsmaster to intrarhev2 failed; return code 150 on target hypervisor: Jan 12 15:45:18 rhev2 kernel: device vnet4 entered promiscuous mode Jan 12 15:45:18 rhev2 kernel: brvlan65: topology change detected, propagating Jan 12 15:45:18 rhev2 kernel: brvlan65: port 3(vnet4) entering forwarding state Jan 12 15:45:18 rhev2 libvirtd: 15:45:18.113: 31182: warning : qemudStartVMDaemon:3336 : Executing /usr/libexec/qemu-kvm Jan 12 15:45:18 rhev2 libvirtd: 15:45:18.119: 31182: warning : qemudStartVMDaemon:3346 : Executing done /usr/libexec/qemu-kvm Jan 12 15:45:18 rhev2 qemu-kvm: Could not find keytab file: /etc/qemu/krb5.tab: No such file or directory Jan 12 15:45:18 rhev2 libvirtd: 15:45:18.332: 8787: error : virCgroupRemoveRecursively:679 : Unable to remove /cgroup/cpu/libvirt/qemu/dacsmaster/ (16) Jan 12 15:45:18 rhev2 libvirtd: 15:45:18.332: 8787: error : virCgroupRemoveRecursively:679 : Unable to remove /cgroup/cpuacct/libvirt/qemu/dacsmaster/ (16) Jan 12 15:45:18 rhev2 libvirtd: 15:45:18.332: 8787: error : virCgroupRemoveRecursively:679 : Unable to remove /cgroup/cpuset/libvirt/qemu/dacsmaster/ (16) Jan 12 15:45:18 rhev2 libvirtd: 15:45:18.332: 8787: error : virCgroupRemoveRecursively:679 : Unable to remove /cgroup/memory/libvirt/qemu/dacsmaster/ (16) Jan 12 15:45:18 rhev2 libvirtd: 15:45:18.332: 8787: error : virCgroupRemoveRecursively:679 : Unable to remove /cgroup/devices/libvirt/qemu/dacsmaster/ (16) Jan 12 15:45:18 rhev2 libvirtd: 15:45:18.332: 8787: error : virCgroupRemoveRecursively:679 : Unable to remove /cgroup/freezer/libvirt/qemu/dacsmaster/ (16) Jan 12 15:45:18 rhev2 libvirtd: 15:45:18.332: 8787: error : virCgroupRemoveRecursively:679 : Unable to remove /cgroup/blkio/libvirt/qemu/dacsmaster/ (16) Jan 12 15:45:18 rhev2 kernel: brvlan65: port 3(vnet4) entering disabled state Jan 12 15:45:18 rhev2 kernel: device vnet4 left promiscuous mode Jan 12 15:45:18 rhev2 kernel: brvlan65: port 3(vnet4) entering disabled state powering off the guest (through "disable" action of the related rhcs service) and powering it on on 6.1 host, I'm able to live migrate it either to the other 6.1 host and to the 6.2 one... /etc/libvirt/libvirtd.conf doesn't contain anything for the host_uuid part as I find in messages of source 6.2 hypervisor..... and dmidecode command succeeds on all the three systems. they are identical servers and for example output on one of them gives: # dmidecode -s system-uuid 34353439-3036-435A-4A38-303330393332 BTW: the contents of the KB referred seem quite limitating in flexibility during upgrade between minor versions....
