Do we really want to support this? We anyway have to discard the state as the clone cannot be the exact same state as the original...so it's not really different from cloning Down. Do you intend to clone like that or keep blocking it altogether? The latter, to block it. Clone-VM invokes create-snapshot and create-snapshot is forbidden on suspended vm so we should block it with a proper error instead of "Internal Engine Error" (In reply to Tamir from comment #0) > Expected results: > 1-5 steps are as expected. > 6. The VM should have been cloned. As mentioned in comment 2, the expectation is to fail with a proper error on the client (UI/API) side Verified on RHV 4.4.3-3. All looks good to me.
Env:
- Engine instance with RHV 4.4.4-2 (ovirt-engine-4.4.4.1-0.1.el8ev) and RHEL 8.3 installed.
- 2 hosts with RHV 4.4.4-2 and RHEL 8.3, one host with vdsm-4.40.37-1.el8ev and the other host with vdsm-4.40.37-1.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. Suspend the VM.
6. Try cloning 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.
5. The VM is suspended
6. The VM clone button was grayed out (Disabled) in the GUI and when I used clone in the rest API I got the following response:
"<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<action>
<fault>
<detail>[Cannot add VM because the VM is in Suspended status.]</detail>
<reason>Operation Failed</reason>
</fault>
<status>failed</status>
<vm>
<name>VM</name>
</vm>
</action>"

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. Suspend the VM. 6. 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. 5. The VM is suspended 6. The VM clone operation has been canceled automatically with the UI message: "Error while executing action CloneVm: Internal Engine Error". Expected results: 1-5 steps are as expected. 6. The VM should have been cloned. Additional info:
