Fix built into libvirt-0.8.2-4.el5 The default ownership of QEMU is root:root on RHEL5.6, it's different from rhel6. When I change the user & group to qemu in /etc/libvirt/qemu.conf manually, the libvirtd start failed with the following error in /var/log/messages: Oct 12 11:11:35 dhcp-93-197 libvirtd: 11:11:35.264: warning : qemudStartup:1656 : Unable to create cgroup for driver: No such device or address Oct 12 11:11:35 dhcp-93-197 libvirtd: 11:11:35.265: error : virGetUserID:2692 : Failed to find user record for name 'qemu': Success Oct 12 11:11:35 dhcp-93-197 libvirtd: 11:11:35.265: error : virStateInitialize:980 : Initialization of QEMU state driver failed Oct 12 11:11:35 dhcp-93-197 libvirtd: 11:11:35.265: error : main:3242 : Driver state initialization failed Oct 12 11:11:35 dhcp-93-197 libvirtd: 11:11:35.266: warning : qemudDispatchSignalEvent:396 : Shutting down on signal 3 We can only test the tunnelled migration with root:root on rhel5.6 now. Can you confirm user 'qemu' exists on your system? The error message there is not very helpful in this case :-) Hi 'JD', I use "libvirt-0.8.2-7.el5.x86_64" to test again ,I can not migrate successfully with '--tunnelled'. It very strange ,in a new enviroment with "libvirt-0.8.2-6.el5",I can not migrate successfully as the result of comment 5 . Issue:At source host,after a long time command will not exits and give a error message .At target host domain "mig" will keep “paused” statu Steps: host A: 1.vim /etc/exports /var/lib/libvirt/images 10.66.93.197/16(rw,no_root_squash) 2. service nfs restart 3. mount 10.66.93.197:/var/lib/libvirt/images/ /mnt host B: 4. mount 10.66.93.197:/var/lib/libvirt/images/ /mnt 5. cd /mnt 6. virt-install -n mig -r 1024 -f rhel55.img --import the guest should boot completely. 7. ssh-keygen -t rsa 8. ssh-copy-id -i ~/.ssh/id_rsa.pub root.93.197 9. virsh migrate --live mig qemu+ssh://10.66.93.197/system --tunnelled --p2p Issue:At source host,after a long time command will not exits and give a error message .At target host domain "mig" will keep “paused” status. Hmm, this is another and more serious bug, the tunnelled migration doesn't work at all on 5.6. I made a new bug 643842 to track that issue. Changing this bz back to ON_QA since it should be fixed, it's just untestable before 643842 is fixed. This is untestable with current state of qemu-kvm but the fix is included in libvirt package anyway so I'm closing this as NEXTRELEASE |
