Here's another approach to consider using the Spring sop. It's very simple and using grouping to control what is and is not influenced by the Spring forces.

I've run houdini in VirtualBox, both in a Winxp image and other flavours of linux. I've not had much trouble other than being quite slow.

It was just an exercise for me, I definitely wouldn't do it for any sort of production or serious testing. You are sharing resources across to OS's and it becomes very difficult to sort out problems you may encounter with houdini.

Dual booting is quite quick now, so that's the way I go. Mind you I'm on linux pretty exclusively and rarely go to Windows.

Try using the Primitive sop after your nurbs/bezier curve. In the Face/Hull folder in the Close U option choose to Unroll.
