Hi,

I'm Kashyap Thimmaraju, a second year PhD student at TU Berlin in
Germany. This is my first post here, and I'm a Xen newbie.

I saw George Dunlap's presentation "Securing Your Xen-Based Cloud" at
the LinuxCon on youtube recently as I am interested in using the
driver domain for networking.

In the presentation he proposed placing the network driver  and
forwarding functionality (bridge, iptables, etc.) into a (network)
driver domain. This is indeed good for security.

However, I am curious if people are really adopting such an approach.
Are there cloud providers or PV vendors deploying such an
architecture? If so, is there any impact on the networking performance
of say VM-VM or VM-Internet traffic?

Thanks,
