Test Steps:
1. Clean install rhvh-4.3.0.6-0.20190418.0
2. deploy hosted-engine
   a: via cockpit UI
   b: via CLI

3. Set the max available memory

Result:
a. For cockpit UI, QE cannot reproduce this issue after trying 5 times
b. For CLI, QE cannot reproduce this issue after trying 5 times

So QE cannot reproduce this issue, maybe I missing some key steps? Could you please give me some points? thanks!

as I mentioned, it happens sometimes.
On the CLI no amount of memory was reserved for the host while on cockpit we reserved in the past 256MB.
Thus, it is more likely that you will succeed reproducing it via CLI and not via cockpit UI.

The Fix was to reserve 512MB on the host. That's why we have a patch in cockpit-ovirt too.

Test Steps:
1. Clean install RHVH-4.3-20190516.1-RHVH-x86_64-dvd1.iso
2. Deploy hosted-engine via CLI
3. Set the max available memory(Get from cockpit wizard)
