Arne and Eric: Based on your latest info and Eric's note I believe I'll give QEMU a try. I like the simplicity (i.e. qemu -fda Bering-uclibc-2.3beta2.img.bin).
I may be picking your brains while I setup the first few machines. Thank you very much. --Cal Webster On Wed, 2005-04-20 at 16:57, Arne Bernin wrote: > On Wed, 2005-04-20 at 16:02 -0400, Calvin Webster wrote: > > > Thank you for the suggestions Arne. > > > > In my original post I was really looking for the fastest way to get 5 > > LEAF routers and 5 or 6 minimal client hosts virtualized.
