Re: [ros-dev] Yet another VM

[Nathan Lane]

I'll probably get another weird email from the postmaster for this, but
it is sufficient to me to say that the GPL allows commercial ventures to
include code without the requirement of making the product open source.
There are a few rules though - and I'm not the one to ask about those,
but I know of many companies that include GPL code in their product
without the need to make their product open source.

It's funny how you're all going on about how good it is without even
having tested it.

QEmu supports multiple snapshots as well, as it does USB, and it's fully
open source. QEmu supports named pipes, mounting raw hard drives and any
other disk that Windows can see, audio, networking etc. So I don't think
it contains anywhere near as many features as QEMU, especially since
most of the advanced ones you mentionned are *not* Open Source.

I'm also quite curious on how they were able to take QEMU (a GPL
product) and add USB support under closed source (which QEMU already has
as GPL). Sounds like a bunch of hacks to me.
