Hi,

if you mean:

"Can I use oVirt Node for running VMs without using oVirt Engine?"

then yes, you can.

oVirt Node is a CentOS Linux derivative and as such you can use virt-manager from your laptop to connect to it and manage VMs there as if it was a normal CentOS.

You can also use cockpit for creating local VMs.

If you mean:

"Can I create VMs from oVirt Node and also manage them from the engine?"

the short answer is no.

The long answer is: you can still try using cockpit-machines-ovirt https://cockpit-project.org/guide/172/feature-ovirtvirtualmachines.html

which was deprecated in oVIrt 4.3 and removed in 4.4.

Or run VMs on oVirt Node and try to make them visible to engine using KVM provider https://www.ovirt.org/documentation/administration_guide/#Adding_KVM_as_an_External_Provider

But I wouldn't recommend using these flows.
