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 at hostA:~# /etc/init.d/apparmor teardown
root at hostA:~# stop libvirt-bin && start libvirt-bin
root at hostB:~# /etc/init.d/apparmor teardown
root at hostB:~# stop libvirt-bin && start libvirt-bin
root at hostB:~# touch /tmp/centos54-1mg.img
root at hostB:~# chown -R libvirt-qemu:kvm /tmp/centos54-1mg.img
root at 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
