Hi there,<br>
<b style="font-family: Tahoma; font-size: small;"> </b><br>
maybe i missed the discussion on the mailing list. Today we installed<br>
a new centos host. Of course it has 7.3 and qemu 2.6 after a yum update.<br>
It can be attached to our cluster wihtout problems. We are running Ovirt<br>
4.0.6 but the cluster compatibility level is still 3.6.<br>
<br>
We can migrate a VM from qemu 2.3 to 2.6<br>
We cannot migrate a VM from qemu 2.6 to 2.3<br>
<br>
What happens:<br>
<br>
- qemu is started on the target host (centos 7.2)<br>
- source qemu says: "initiating migration"<br>
- dominfo on target gives:<br>

Anyone experienced this behaviour? Maybe desired?<br>
