Hello,
we have two 2-node clusters running on CentOS 6.4. Only service managed by
clusters are KVM virtual machines. Both clusters have access to an NFS-server on
which the config and storage files of the VMs reside.
Now I want to move a VM from cluster1 to cluster2 with the following approach:
On cluster1:
Edit cluster.conf and remove vm1 config
cman_tool version -r
virsh migrate --live vm1 qemu+ssh://HOST1_CL2/system tcp:HOST1_CL2
(After live migration finished)
On cluster2:
Edit cluster.conf and add vm1 config
cman_tool version -r
clusvcadm -e vm:vm1
(I have autostart="0" so I need to enable the VM. Cluster-SW finds running
vm1
and clustat is OK).
I tried it and it worked -- but is it save? Any comments (expect to ask why we
have two 2-node clusters :-) ) ?
Best regard,
Ralf
Did you try;
clusvcadm -M vm:foo -m target.node
That is how I live-migrate VMs. No need to remove it from the cluster
and then re-add it.
