Things might have improved with qemu, I haven't tried it recently.
Xen is another option to Run Linux "under" NetBSD. Ubuntu as PV (or the newer
PVM) Guest could be more efficient then VirtualBox - but bit bit more difficult
to setup if you need GL in the guest...
Running Xen with Ubuntu as Dom0 ("Host") instead and NetBSD as a PV (or PVM)
DomU ("Guest") is an option too. Depending from hardware PV or PVM should be
the "fastest" option.
If you just want Ubuntu to surf a few websites (without any 3D hardware accel
and such stuff required) Ubuntu as PV or PVM DomU should be light and "slight"
enough.
