Hi,
The number of vNUMA nodes does not limit the number of sockets, cpus, or
threads. The VM can have any number of sockets.
When using the UI, the vCPUs are distributed equally across all vNUMA
nodes. When using the REST API, it is up to the user to specify which vCPUs
are assighned to which vNUMA nodes.
Best regards,
Andrej

Hi,
when I want to use vNUMA for VMs is it necessary that the number of VM
virtual sockets corresponds to the number of vNUMA nodes?
concrete example:
hypervisor host has 2 physical cpus
VM has 2 vNUMA nodes and uses CPU pinning which distributes the VCPUs
equally over both physical CPUs
is it necessary for the VM to have 2 virtual sockets or is it ok for
virtual socket count to be powers of 2 (eg. 16)?
thanks
matthias
