Re: [Xen-devel] GPL release of Virtual Iron sources

[Anthony Liguori <aliguori@xxxxxxxxxx>]

This is a rather radical departure from where Xen is currently going.  
Is your goal to get this stuff in mainline or were you just making 
everyone aware of your changes?
If you're interested in getting it into mainline, we can discuss some of 
the details but as I said, this is rather different from where Xen is 
currently going...
