Hi tuxen the cores-per-socket does not works in my server, did you have any ides, can help me to unmimite vCPU ?

xe vm-param-set platform:cores-per-socket=24 uuid=<VM UUID>

Hello!
We have a server form Dell PowerEdge R840 with four socket: 4 x Intel Xeon Gold 6254
xl info in this server :
nr_cpus : 144
max_cpu_id : 223
nr_nodes : 4
cores_per_socket : 18
threads_per_core : 2

We assign 96 vCPUs to a VM CentOS Server, when we fire lscpu it only shows 64 vCPUs.

We use command settings the VCPUs-max = 96, like this

Is there any other parameter to force "Threads per core" Pass through or unlimit it ?
