> Hello,
> My current setup includes a dual cpu, quad core + HT, however in the ACS dashboard the
"CPU sockets" says only one.
> This value is wrong and as I undestand it, it is taken from "virsh nodeinfo" which is
known to give misleading information, as it reports stuff "per NUMA cell"
> As per the man page of virsh, the number of real physical sockets should be calculated
as "NUMA cell" multiplied by "CPU sockets".
> e.g.
> virsh nodeinfo
> CPU model:           x86_64
> CPU(s):              16
> CPU frequency:       2393 MHz
> CPU socket(s):       1
> Core(s) per socket:  4
> Thread(s) per core:  2
> NUMA cell(s):        2
> physical cpus = "CPU socket(s):       1"  *  "NUMA cell(s):        2" = 2 (correct)
> Additional information can be taken from "virsh capabilities|grep socket_id" (xml output)
e.g.:
> virsh capabilities|grep socket_id
>             <cpu id='0' socket_id='1' core_id='0' siblings='0,8'/>
>             <cpu id='2' socket_id='1' core_id='1' siblings='2,10'/>
>             <cpu id='4' socket_id='1' core_id='9' siblings='4,12'/>
>             <cpu id='6' socket_id='1' core_id='10' siblings='6,14'/>
>             <cpu id='8' socket_id='1' core_id='0' siblings='0,8'/>
>             <cpu id='10' socket_id='1' core_id='1' siblings='2,10'/>
>             <cpu id='12' socket_id='1' core_id='9' siblings='4,12'/>
>             <cpu id='14' socket_id='1' core_id='10' siblings='6,14'/>
>             <cpu id='1' socket_id='0' core_id='0' siblings='1,9'/>
>             <cpu id='3' socket_id='0' core_id='1' siblings='3,11'/>
>             <cpu id='5' socket_id='0' core_id='9' siblings='5,13'/>
>             <cpu id='7' socket_id='0' core_id='10' siblings='7,15'/>
>             <cpu id='9' socket_id='0' core_id='0' siblings='1,9'/>
>             <cpu id='11' socket_id='0' core_id='1' siblings='3,11'/>
>             <cpu id='13' socket_id='0' core_id='9' siblings='5,13'/>
>             <cpu id='15' socket_id='0' core_id='10' siblings='7,15'/>
