[ovirt-users] live migration

[Demeter Tibor]

Hi, 

Every host are different hostnames, it does not change since reinstall. 

Maybe node1 got diffrerent uuid than before. 

Ovirt had out-of-box live migration feature yet? 

Thanks.

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?​
