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.

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?
