Additional info:

Comment 1 Frantisek Kobzik 2014-06-18 12:50:22 UTC
The feature should be actually disabled for CC < 3.6 because of missing implementation of rng device passthrough in correspodning version of qemu in RHEL (it has not been backported yet).

I forgot to enhance doc text of the original BZ to clarify usage of the feature. I'll try to do it now.

I'll also push an engine-config patch that exposes configuring availability of rng sources per CC.

Comment 2 Michal Skrivanek 2014-07-17 11:22:15 UTC
and the checkbox should be greyed out

Comment 3 Frantisek Kobzik 2014-07-18 14:46:13 UTC
1, Broken layout - it appears that this is no longer reproducible when instance type "chain" icon is present,
2, checkbox is actually greyed out, it just looks weird.

The only thing that is needed is to re-enable possibility of selecting virtio rng sources in cluster dlg for cluster >= 3.5 (that corresponds to rhel 6.6). Currently it's disabled (although it can be change via VirtIoRngDeviceSupported option per CL).

Comment 4 Frantisek Kobzik 2014-07-18 15:21:18 UTC
So it seems that the possibility of selecting virtio rng sources in cluster dialog is already enabled for CL >= 3.5. Closing this bug.

For further information on setting rng in the engine, refer to doc text of bz #977079.
