I am testing the deployment of oVirt using ovirt-node next-gen and ovirt appliance on a nested KVM environment.

My base system (the physical machine) is a FC24 with 16Go of RAM and nested KVM enabled.

I used NFS for storage.

Test with oVirt 4.0.3:

- I created two hypervisors 5Go of RAM each and 4vCpu.

- I installed ovirt-node next-gen OS.

- I downloaded ovirt appliance and started the engine deploy using generated configuration from cloud-init (I reserved 2Go of RAM for the VM-engine).

Problems :

- I couldn't add the second hypervisor from the engine's GUI, when I tried to do it, ovirt-engine crashed.

- I tried with the command line, the process terminated with errors.

- There is no create a new ISO or Export domain only Data domain in the select list.

Unfortunately I deleted the two hypervisors. 

Test with oVirt 4.0.4 RC3 :

Problems:

- I couldn't add the second hypervisor from the engine's GUI, when I tried to do it, ovirt-engine crashed.

- After adding the Data domain, the hosted_storage was added successfully, but the VM engine was not imported successfully, it's does not appear on the VMs tab.

- There is no create a new ISO or Export domain only Data domain in the select list.

- I added the second hypervisor from the command line successfully.

- I tried to put the first hypervisor in maintenance mode, migration of the VM engine was started, from the command line I could see that the VM is running on the second hypervisor, but the migration process didn't terminate, I tried to reactivate the first hypervisor and put it in maintenance mode again, this time the ovirt-engine crashed.

Regards.
