Issue/Introduction
Symptoms:
- Unable to assign 4 CPU cores to a VM on VMware ESXi version 6.5.0 build 4887370, you are limited to 2 CPU cores per socket.
- The only way to assign 4 CPU cores is by using 2 cores per socket.
Cause
The host is taking the minimum socket as maximum as result you would not be able to increase the socket.
<vmw:CoresPerSocket ovf:required="false">2</vmw:CoresPerSocket>
<vmw:CoresPerSocket ovf:required="false">2</vmw:CoresPerSocket>
Resolution
The issue is resolved with VMware ESXi version 6.5.0 update01 build 5969303.
As a workaround, the OVA file can be modified to allow a higher number of cores. See the following example of what is changed in the OVA file.
