ovirt-srv11

[Anton Marchukov]

Hello All.

The fixed hook is only in 3.6. The hook version in 3.5 does not work.
Although we can install the hook from 3.6 into 3.5 as it should be
compatible and this is how it was done on the test slave.

Also just to remind some drawbacks of that solution as it was:

1. It was not puppetized (not a drawback, just a reminder).
2. It will break vm migration. Means we will have to manually move the vms
when we do host maintenance or need to automate this as fabric task.

Anton.
