[Xen-users] Finally moving to xen 3

["Frank DiRocco" <ofanged1@xxxxxxxxx>]

Ok, so I finally feel confident with xen2. Therefore, i have now
completely confused myself by moving on the xen3. I set up a debian
sarge machine with one network interface configured via dhcp. If I
understand corectly, first eth0 is started by system boot process. It
gets its address via dhcp. Then xend creates xenbr0, I may be mistaken
but I have compared xenbr0 to a switch in my mind. Now eth0 is brought
down. The IP and MAC from the "real" eth0 are now copied to veth0. The
now down "real" eth0 is renamed peth0. The veth0 which is a clone of
the "real" eth0 is renamed to eth0. So, my dom0 should think the "new"
eth0 is the original eth0 and use it for network traffic. 

eth0 -----------------------------------------------------------dom0

eth0 -------------------------------[xenbr0]

Xeth0X(down)------------------[xenbr0]
                                         
vif0.0

veth0

peth0 -----------------------------[xenbr0]
                                         
vif0.0

veth0

peth0 -----------------------------[xenbr0]
                                         
vif0.0

eth0------------------dom0

I think I understand the theory behind the way the virtual networking
works, but when I log in and ifconfig I see peth0 vif0.0 xenbr0 but I
don't see eth0 and networking doesn't werk. I have tried ifconfig eth0
up and I do get an address via dhcp, but still have no network access.
It was my understanding that the "new" eth0 would be brought up
automagicly, but this does not seem to be the case with my mess. Thanks
in advance for shining light this way.
