Hi,

I reinstalled one of my nodes (node1) because I have to replace my hdds.
I installed centos 6.6 minimal, but on node re-adding procecure it installed newer qemu-kvm-rhev packages.
Since reinstall I can run VMs on this node and I can do live migrate from this node to other, but not backwards.
I remember, maybe one years ago it was required to install redhat's version of qemu-kvm-rhve package for this feature.
Is it necessary yet?
my versions:

node0 KVM: 0.12.1.2 - 2.415.el6_5.14, LIBVIRT: libvirt-0.10.2-46.el6_6.1
node1 KVM: 0.12.1.2 - 2.448.el6_6.4, LIBVIRT: libvirt-0.10.2-54.el6
node2 KVM: 0.12.1.2 - 2.448.el6_6.4, LIBVIRT: libvirt-0.10.2-46.el6_6.1

Can I upgrade manual these hosts?
I haven't restart my hosts because node0 and node2 is gluster replicate.


Thanks in advance,
Tibor

​not sure about the versions,

but what is the error you see in source host vdsm.log when migration fails?​
