loading "dpci" module from vancouver fails.

[Shyamali Mukherjee]

My grub menu entry  looks like below:


SARGS="S0_DEFAULT hostserial hostvga:0x40000,0x40000 
hostkeyb:0,0x60,1,12 startlate:0xfffffffd"
VMMARGS="PC_PS2 kbmodifier:0x40000"

This setup has DMA remapping. The first Linux VM has direct access to
your first network card and creates a bridge to the virtual
network. You need Intel VT-d support for this.

Observation:
--------------------
1. I can not have "hypervisor serial  dmar".. Can ONLY use "hypervisor  
dmar"  or "serial".
2. I figured that it fails to load "dpci" module.

I have looked at pcidirect.cc available under:
nova-userland-0.2/vancouver/model/pcidirect.cc

It says:

"Example: Use 'dpci:2,,0,0x21' to attach the first network controller to 
00:04.1.",
Then from build_cd.sh I see "dcpi:2,0,0"
But boot fails:
Please see screenshot attached.

3. where can I find "sigma0" and "munich" sources. It seems in "NUL 
release 0.2" has these prebuilt. Only sources I see are like for 
vancouver.nul.
