  • Thread-topic: is a pure usermode backend possible?

Is there any reason why a purely user mode backend driver could not work
in Dom0? I believe that the xenstore, grant table, and event channel
interfaces all exist so I can't see why not, unless creating nodes under
/local/domain/0/backend might confuse something?

Assuming it's possible, are there any performance reasons or other
reasons why it might not be a good idea?

Thanks

James
