Using that, and this xm file

kernel="/mnt/tmp/openwrt/openwrt-x86-xen_domu-vmlinuz"
root='/dev/xvda2 rw'
memory=256
vcpus=1
localtime=0
disk=['phy:/dev/sdc,xvda,w']
extra="console=hvc0 debug loglevel=10 iommu=soft"
name="openwrt"
on_crash="preserve"
vfb = [ 'vnc=1, vnclisten=0.0.0.0,vncunused=1']
pci = ['04:00.0']

where
04:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 13)

I can't get the sky2 adapter to work at all.

Just to make sure it wasn't your build ...

... I tried to follow those directions and found that it would not work.
I can't get the xen-pcifront.ko file at all on any of the *combined.img images.


I made this patch thinking it was due to the name of the module being different:

but it still would not include the xen-pcifront.ko file on the *combined-ext4.img.gz
file. Any ideas what I am doing wrong?
