Cannot add to a pool an xcp-ng host with "older" cpu parameters

Hello Everyone,
Please, see the two embedded images.

Even after clicking on “proceed” button, with following restart, hlab1 is “staying outside” of the pool.
If there is solution for this ?

Good morning @LTS_Tom,

Do you think, there is a solution for this issue ?

What CPUs do each server have?

Xen used to be very picky about the CPUs for different hosts that were to be part of a pool, I think it’s a bit more lenient now, but there may still be some limitations on what can be part of a pool.
