i have my dom0 not showing the pci network interfaces upon lspci.
dom0 only has one dummy interface when it boots
/etc/modules contains "dummy -o dummy0

in my domU config file i added the lines
nics = 3
pci = [ '00,11,0' , '00,12,0' ] #these are the address of the nics I hide from dom0

once both domains are loaded ifconfig shows dummy0 configured the way it was in /etc/network/interfaces
additionally vif1.0 and vif 1.1 are shown unconfigured

brctl show
xen-br0        8000.c65260b5d9b3        no        dummy0

xm vif domU
(vif (idx 0) (vif 0) (mac aa:00:00:0e:b1:75) (vifname vif1.0) (evtchn 14 4) (index 0))
(vif (idx 1) (vif 1) (mac aa:00:00:0e:b1:75) (vifname vif1.1) (evtchn 15 5) (index 1))

Inside of my domU I have configured eth0 and eth1 with addresses on the LAN and the proper gateway yet i can not ping out. I really think im missing some small point. Also I am confused by the above output of "brctl show", does this mean xen-br0 is connected to dummy0 vif1.0 and vif1.1 or just connected to dummy0 and vif's are not connected to anything on dom0? On another note, i tried lspci inside of domU and it showed nothing, but i didn't expect it to. so, is there any way to verify the pci devices are attached to the domu?

Thank you,
Frank  Di Rocco
