[libvirt-users] block migration

Hello, I'm trying to use block migration with below procedure, but got some errors. I would highly appreciate if anyone give me a hand.. There are 2 hosts(hostA and hostB), both OS is Ubuntu 10.10(merverick). And a VM(named centos54-1mg) is running at hostA(centos54 64bit). [package version] +++-=====================-=====================-=================== ii kvm 1:84+dfsg-0ubuntu16+0 dummy transitional ii libvirt-bin 0.8.8-1ubuntu3~ppamav the programs for ii qemu-common 0.14.0~rc1+noroms-0ub qemu common ii qemu-kvm 0.14.0~rc1+noroms-0ub Full virtualization [proceduere] root@hostA:~# /etc/init.d/apparmor teardown root@hostA:~# stop libvirt-bin && start libvirt-bin root@hostB:~# /etc/init.d/apparmor teardown root@hostB:~# stop libvirt-bin && start libvirt-bin root@hostB:~# touch /tmp/centos54-1mg.img root@hostB:~# chown -R libvirt-qemu:kvm /tmp/centos54-1mg.img root@hostA:~# virsh migrate --live --copy-storage-all --p2p --direct centos54-1mg qemu+tcp://hostB/system [NOTE] 1. What I was being careful is permission. Therefore, apparmor is off, libvirt is running as root. 2. normal live migration is successfully finished. So, libvirtd can communicate between hostA and hostB. 3. Regarding to options "--live --copy-storage-all --p2p --direct", I think --copy-storage-all is minimum, so I was trying to change pairs of options, but no good result. The error logs and configuration at hostB are attached. Thanks in advance mkey
