[ovirt-users] After upgrading to 4.1.4 unable to start VM or migrate them

Well, if you would like to help us to find the cause then we need to know more details.

- what was your original version?
- what was your original scheduling policy on the cluster
- could you provide
  * /var/log/ovirt-engine/setup/ovirt-engine-setup-20170801112218-piffzl.log
  * /var/log/ovirt-engine/engine.log

You have backup of your original engine DB in /var/lib/ovirt-engine/backups/,
thus you can import this DB via psql into a temporary DB and inspect the DB
for original settings.

Ideally you can submit a BZ at https://bugzilla.redhat.com/enter_bug.cgi?classification=oVirt
