I have a fully patched / up-to-date engine:
Software Version:4.5.4-1.el8

And a fully patched, up-to-date host.

Name         : ovirt-host
Version      : 4.5.0
Release      : 3.el8
Architecture : x86_64
Size         : 11 k
Source       : ovirt-host-4.5.0-3.el8.src.rpm
Repository   : @System
From repo    : centos-ovirt45

The host has 32GB of RAM, and there's only 1 VM on this host.
When I try to add more CPUs to the VM from the manager UI, I get the following error:
  • The requested number of vCPUs is not available on the host the VM is running on
What's going on here, and why can I not add more vCPUs to this VM?
