Description of problem:
When cloning a running VM, the cloned VM fails to be created.
Added logs.

Version-Release number of selected component (if applicable):
RHV 4.4.3-10 (ovirt-engine.noarch 4.4.3.8-0.1.el8ev)
RHEL 8.3 x86 hosts and engine.
vdsm.x86_64 4.40.35-1.el8ev on the hosts.

How reproducible:
100%

Steps to Reproduce:
1. Create a 4.5 data center and a 4.5 cluster.
2. Install the host and create a new NFS storage domain.
3. Create a VM with a disk and wait for its creation.
4. Run the VM.
5. Clone the VM. 

Actual results:
1. The 4.5 data center and the 4.5 cluster were created.
2. The host was installed and the NFS storage domain was created.
3. The VM with the disk was created.
4. The VM is running.

I verified the bug on RHV 4.4.3-13. All looks good to me.

Env:
  - Engine instance with RHV 4.4.3-13 (ovirt-engine-4.4.3.10-0.1.el8ev) and RHEL 8.3 installed.
  - 3 hosts with RHV 4.4.3-13 and RHEL 8.3, vdsm-4.40.35.1-1.el8ev

Steps:

In Admin Portal:

1. Create a 4.5 data center and a 4.5 cluster.
2. Install the host and create a new NFS storage domain.
3. Create a VM with a disk and wait for its creation.
4. Run the VM.
5. Clone the VM.


Results (As Expected):
1. The 4.5 data center and the 4.5 cluster were created.
2. The host was installed and the NFS storage domain was created.
3. The VM with the disk was created.
4. The VM is running.
