---------------------------------
Hi Andrija,
Unless the number of sockets is not reported correctly, then I don't think this
is the right place for your issue.
It looks more like an issue of how CPU is reported by OS/libvirt.
> Wrong number of sockets reported

> Key: CLOUDSTACK-9226
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9226
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM
> Affects Versions: 4.6.0, 4.7.0
> Environment: KVM, CentOS 7 mgmt + HV
> Reporter: Nux
> Labels: dashboard, kvm, sockets, statistics
>
> 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'/>
