Check whether Vmware provides CPU virtualization support for the virtual machine. Connect SSH to EXSI and configure vi /etc/vmware/config. Add vhv.allow = “TRUE”, then find the CPU of the virtual machine in the web management interface and start virtualization support.

The implementation of kvm requires hardware to support virtualization. The "hardware" of centos is virtualized and does not support virtualization.
Use virtualbox or qemu instead (nested virtualization, efficiency is worrying)
