A sample XML format that can be used to define a linux container domain:

Having thought about this all since our previous round of discussions on
the matter I'm of the opinion we should /not/ use the <container> block
for filesystem setup - it should be part of the <devices> block. This will
simplify impl for apps which already have support for dealing with devices
and hot add/remove (virDomainAttachDevice/virDomainDetachDevice). The
<init> element can stay in <container> or perhap go inside an <os> block
since that's where we describe booting for non-container virt.
That makes sense to me. I guess I'd lean towards leaving <init> in the
container block since a container isn't really starting a new os image.
Perhaps Dan Smith has some comments on this...
