[virt-tools-list] [RFC] enable direct interface selection



Hi,
here are two patches to enable direct interface selection when defining
a new VM. One is for virtinst and one is for virt-manager. I combine
them in one posting because they are closely related.

If the approach looks okay, I am happy to resend as attachments if
necessary.
If the approach looks not okay, please advice ....





The following patch adds support to select direct interfaces
when defining a virtual machine via virt-manager
