After several years wit physical machines – I took a choice with converting all setup to VM (VirtualMachines), for comsuming less power and have more power behind the machines.
I have tried both Windows HyperV, Vmware ESXi and more – but in the end I found this https://pve.proxmox.com
I have a little server IBM 3850 X5 system – with 4x2000ghz CPU and 512GB RAM…
After downloading the ISO file – I burned it on CD – and installed the Proxmox on a 16GB USB harddisk – which is installed directly on the motherboard. – This gives a perfect setup for running VM in a enviorment that doesn’t require a lot of space/hardware to run the HyperVisor fra proxmox.
