  • Proxmox is based on kvm/qemu, and is very resource conservative. There is virtually no impact on performance due to the hypervisor, even on older processors. Scheduling on the cpu and hypervisor makes running multiple VMs at the same time trivial as well. RAM and I/O bandwidth are the two things that can affect performance. Running out of RAM due to too many VMs will grind you to a halt, but so would running too many applications or containers on bare metal. Running everything off of one spinning sata disk will make it impossible, but again, same downfall on bare metal.

    Those minimal impacts to performance are a minor nuisance compared to the ability to run experiments and learn on sandboxed VMs. Now that TrueNAS has better virtualization support, it has caught my eye as a better homelab solution, but I will always have a proxmox server running somewhere in my stack just due to the versatility it gives me.
