CPU Features

churchers

If you have an old pool and want to upgrade, attaching new hardware.
You can get the following.

Once all the old servers are removed, how can you check that the CPUs are working at their best?

Thanks in advance.

I don't know how it behaves in this case. I think it might stay with the same feature as before removing the older hosts from the pool. You can check the CPU features before and after with:

xe pool-param-get uuid=<POOL UUID> param-name=cpu_info

Example output:
