Can't provision VM from template

[Zeashh]

When trying to provision a VM from a template, we get 2 distinct errors:

• when provisioning from a default template (rhel9-server-small):

<AEMethod update_provision_status> VM Provision Error: [EVM] VM [provision-test-rhel9] Step [CheckProvisioned] Status [Error Creating VM] Message [[Fog::Kubevirt::Errors::ClientError]: HTTP status code 422, admission webhook "virtualmachine-validator.kubevirt.io" denied the request: spec.template.spec.volumes[1].cloudInitNoCloud must have at least one userdatasource or one networkdatasource set. for]

• when provisioning from a custom Ubuntu template (YAML provided below):

<AEMethod update_provision_status> VM Provision Error: [EVM] VM [provision-test-ubuntu] Step [CheckProvisioned] Status [Error Creating VM] Message [[Fog::Kubevirt::Errors::ClientError]: HTTP status code 422, admission webhook "virtualmachine-validator.kubevirt.io" denied the request: Running and RunStrategy are mutually exclusive for POST https://ocp.domain.com:6443/apis/kubevirt.io/v1/namesp]

Both templates work when used the same way from the Openshift console. I'll also note that we're never given the choice to choose the datastore for the VM disk.

Steps to reproduce:

• Select desired VM template
• Click "Lifecycle" and choose "Provision VMs using this Template"
• Fill out form only with necessary information (e-mail. VM name)
• Submit form
• Approve VM creation request
• See errors above depending on the chosen template

Versions:

• ManageIQ: radjabov-1.20250408024349_e386fb4
• Openshift: 4.18.8 (error persisted throughout several 4.17.X versions while we were in the process of upgrading)

Hey @Zeashh this sounds like another issue, ManageIQ/manageiq-providers-kubevirt#275 (comment)

Can you try setting the root password and see if that resolves the issue for you?

[Zeashh]

I patched the custom template to fix the aforementioned error. I just had to removed the mentioned conflicting field.

As for the root password, I'm assuming you're referring to the "Cloud user password" option. Setting it does help in the sense that VMs are created (though the password doesn't apply as far as I can tell), but the provision requests still fail:

<AEMethod update_provision_status> VM Provision Error: [EVM] VM [provision-test-rhel9] Step [CheckProvisioned] Status [Error Creating VM] Message [Validating New VM] 

This validation task repeats 100 times and then fails. I've also noticed the dashboard hangs after a while until I manually refresh it (newly created VMs don't show and some functions in the dashboard (shutting down a VM for instance) stop working entirely).
