Surely QEMU/KVM supports booting from bare metal hard disks (not files), so you could put FreeBSD on the disk you want to eventually boot directly from, and initially try it under KVM. I actually had a setup where I would boot the same FreeBSD disk on my desktop both directly on metal and under Hyper-V :) But anyway, I think you'd notice the difference even on microSD. The performance on the VPS is *that* bad.
