The code from 2.6.35-rc5-pvhvm-v6 works well!  Thanks!  I can access /dev/hda created by blkfront.  However, the netfront driver still can't detect the MAC address of the nic if I unplug it.  (If I don't unplug it, 8139cp works with the device just fine)  And this code there seems to be no dependency on the loading order of platform-pci and netfront/blkfront.

Hi Stefano,

Great.  I will test the new code this weekend.  I will also try to figure how exactly the module initialization fails when all three are compiled in.

As for the network MAC address problem, the card is working just fine if I don't unplug it and let 8139cp take over the device.  So the bridge is set up correctly, isn't it?

I took some time to read the code again and do few tests: it seems to me
that everything is working just fine in all cases. I am not sure what's
wrong with your setup but I can boot my guest with all three components
built-in or modules.

the new branch is ready, please give it a try and let me know.

do you have a bridge correctly configured in your testbox?
