I have created a boot script for managing vimages (downloadable as a FreeBSD package) and made a little write-up on how to use it... http://druidbsd.sf.net/vimage.shtml Note that I use netgraph for bridging (not if_bridge+epair method which seems to be popular in some other setups -- we've benchmarked netgraph and it scales well). Not to mention that "ngctl dot | dot -Tsvg -o network.svg" can produce nice pretty graphs of your vimage structure when using my setup. > AFAIK, VIMAGE is still experimental feature. Works great, tho, seriously! We're multiplexing hardware 20:1 and could probably push it further (but have conservatively kept things at about 2-3x the number of logical CPUs for number-of-vimages (tho, we have benchmarked up to 65530 nodes on a single bridged network connection before netgraph would refuse to make another (impressive -- but not nearly as impressive as the ~90 minutes it took ifconfig to list all the interfaces lol?). -- Devin _____________ The information contained in this message is proprietary and/or confidential.
