Description michal 2021-02-02 12:31:39 UTC 
version: 
rhv- 4.4.4.7-0.1
ocp -4.7.0-0.nightly-2021-01-31-023653

steps:
1) Install a cluster with the VMs on High performance for master and worker node
2) verify that special configuration implements on rhv UI for worker and master node 

special configuration:

 CPU host passthrough
- Disable ballooning
- Enable serial console
- Make the VM headless

actual: 
when installing vms with High Performance,  special configuration implement only for master node

expected: 
when installing vms with High Performance, the special configuration should implement for master node and worker node

> @gzaidman what's the status on this please?

Wanted to handle it in the refactoring and add it to the go-ovirt-client
Comment 5 Sandro Bonazzola 2021-11-25 12:29:35 UTC 
Waiting on changes in go-ovirt client, to be reviewed next week
Comment 10 Ivana Saranova 2022-09-30 18:18:40 UTC 
Steps:
1) Change configuration before OCP installation, so that the worker VMs are high-performance. (vmType: high_performance)
2) Check that worker nodes have these options set as followed:

    Memory Ballooning - disabled
    Soundcard - disabled 
    Headless mode - enabled
    VirtIO Serial Console - enabled
    Migration - only manual
    Pass-Through Host CPU - enabled

Results:
Worker nodes are created as high-performance with all the options set correctly.

Verified in:
ocp-4.12.0-0.nightly-2022-09-28-204419
rhvm-4.5.3-0.2.el8ev.noarch
