I have been exploring different options for running a server to host VMs.
What I have found as options are:
- VMware vSphere Hypervisor
- Citrix Hypervisor
I chose VMware vSphere Hypervisor as I found that it has the most common hardware support and the amount of information online is much more extensive, making it easier to troubleshoot and use. For the rest, they are a valid choice for hosting of VM except unraid which is more a software for NAS.
