These are Dell R630s with 2 physical CPUs. Intel(R) Xeon(R) CPU E5-2640 v3 @ 2.60GHz CPU Cores per Socket: 8 Ooooh, so even though there are 32 logical cores, the physical CPUs are quad core. Is there a downside to enabling "Count Threads As Cores" in the cluster configuration? Why would that not be enabled by default?

Hello,
Hardware? As far as I remember you cannot assign more vCPU than the number of physical cores you have, unless you enable "Count Threads As Cores" in the cluster configuration, and even than, the number of vCPUs is limited to the number of SMT threads you have.

And a fully patched, up-to-date host. [root@cha3-storage dwhite]# yum info ovirt-hostLast metadata expiration check: 1:33:40 ago on Sun 04 Jun 2023 09:28:39 AM EDT.

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?
