[ovirt-users] Cannot change Cluster Compatibility Version when a VM is active

Hi all,

  I am trying to upgrade an oVirt installation ( to 4.0. My datacenters and clusters have 3.5 compatibility settings.

I followed the instructions from http://www.ovirt.org/documentation/migration-engine-3.6-to-4.0/ but cannot proceed in engine-setup as 3.5 compatibility is not supported.

When trying to change cluster compatibility from 3.5 to 3.6 I receive "Cannot change Cluster Compatibility Version when a VM is active. Please shutdown all VMs in the Cluster." According to https://bugzilla.redhat.com/show_bug.cgi?id=1341023 this should be fixed in 3.6.7. Any ideas?

Best Regards,
Simone Bruckner
