Re: [Xen-devel] [PATCH] xen-2.0: privileged port connections

[Anthony Liguori <aliguori@xxxxxxxxxx>]

So, here's my concerns:

1) ports < 1024 are reserved although 732 is currently unassigned
2) unix domain sockets would solve the same problem
3) this approach is not flexible for finer grain control
4) you still have to find a way to deal with the consoles
5) you still have to deal with xfrd

With all that said, I'd like to see this applied as it's better than 
leaving everything out in the open.
Regards,
Anthony Liguori
