Hi, for me OST upgrade-from-release-suite-master update_cluster_versions is failing with 004_basic_sanity.update_cluster_versions (from nosetests) Failing for the past 1 build (Since Failed#5442 ) Took 1 min 16 sec. add description Error Message Fault reason is "Operation Failed". Fault detail is "[Update of cluster compatibility version failed because there are VMs/Templates [vm-with-iface, vm-with-iface-template, vm0, vm1] with incorrect configuration. To fix the issue, please go to each of them, edit, change the Custom Compatibility Version of the VM/Template to the cluster level you want to update the cluster to and press OK. If the save does not pass, fix the dialog validation. After successful cluster update, you can revert your Custom Compatibility Version change.]". HTTP response code is 500.
