Xen users - Feb 2010 - vif = [ '' '' ] vs. vif0 = [ '' '' ] in HVM DomU configuration file

Hello,

I was hoping to get an understanding on what the difference between using a vif
vs. a vif0 line in the HVM DomU configuration file was?

Is vif0 actually legal?

I was getting the "vif could not be connected. Hotplug scripts not
working" error, and by changing vif to vif0 corrected the problem,
immediately.

Also in my windows XP guest I see an unknown PCI device. Is this possibly the
network card?

I don''t think so. Do you have a working network emulated network card
inside domU? Non-existing configuration items in old-style config file
does not cause error, but simply ignored.

No. It''s Xen PCI device. Once you have driver for that (using PV
drivers), you''ll be able to get additional PV hardware (NIC and disk
controller).

There
is no working network emulated card inside the DomU. I figured out now that the
vif0 option was just being ignored then. I guess it through me off when I could
VNC to the DomU, but then again that service was provided by connecting to the
Dom0.

It
appears Ian Tobin (itobin@tidyhosts.com) is
having a similar problem with the PV OPS git branch kernel. I am using a 64-bit
Debain Lenny as well.



Perhaps the kernel .config options pertaining to networking for the Dom0 kernel
is to blame. Certain options like 802.1d (bridging) and other options much be
enabled right? 



It would be much appreciated if someone could point out or put together a guide
to help configure custom DomU and Dom0 kernel, if its not too much to ask?



When I use the Debian 2.6.26-2-xen-amd64 kernel, I do not get the "vif
could not be connected. Hotplug scripts not working". That is why I
believe the problem lies in the kernel.
