I know I have asked this before, but I am having trouble
understanding the role of each component in the new 1.3 world:
In 1.3 networking if Xen has no
devices, and domain 0 owns and operates the NIC – does Xen have any role at all in networking for the guest OS’s?
Which network device driver will a guest OS use?
Do all the vnetif rules defined in
Domain 0 now get interpreted by Domain 0 vnet driver?
Or still by Xen?
How do the actual packets (that will be routed to a guest) flow
from the physical NIC – (received by a domain 0 driver, routed/filtered by ???, passed over a evtchn to a
guest driver?)
