If you want to go classy, you could have smaller disks (maybe SSD?) in
raid-1 for the system, and larger disks also in raid-1 for your VMs.

Something I do often is reserving a few GBs of non-raided space in the
disks, which I then allocate to swap (raid-1 swap is wasteful)

I strongly recommend you use lvm for your storage management needs, it
works pretty well and is quite flexible.

I usually keep my dom0 memory requirements pretty low (<= 4GB), and as
for CPUs remember the NetBSD dom0 is not SMP-capable yet.
