Yes, I have experienced with HCI by using OpenStack and Ceph.

I have done some performance test by using CBTool which is the corr of SPEC
Cloud IaaS benchmark. So, so the result can be compared with published SPEC
Cloud IaaS result as long it has same benchmark parameters.

Maybe you can refer to OpenStack surveys. It seem that on any forms
(including customized), OpenStack os popular for public cloud.

Actually, VDI consists managed desktop VMs. I haven't use it but maybe
Guacamole can be used for VDI on OpenStack.

OpenStack includes self service capability. Yes, it has template based
deployment like Heat and catalog based deployment like Murano.

> 6. What is the alternative of VMWARE Network Insights and VMWARE

I use other open source products for monitoring and log analysis. Somethink
like Prometheus, Loki, etc.

I have no idea about this. But it is hard to have apple to apple comparison.

There are some cloud management products which are compatible with
OpenStack. But for me, Ansible and/or BASH scripting are good enough.

I have no idea with this.

It seem OpenInfra doesn't, but OpenInfra member do. CMIIW.

On OpenStack, every tenants can be fully isolated. Anyway, some security
products may have another approach to enhance the security. Floating IP
concept is good for hiding non service (externally) instance.
