Re: [Xen-users] I've exhausted my brain trying to get xen toboot...please help

Heh,

Thanks for the reply,

I finally got the dom0 kernel to boot...by building SATA and SCSI
support built-in to the kernel...

Now....D'OH! The kernel doesnt see my BCM NIC....grrr.....

It boots OK but when I do "ifconfig -a" I get all of the virtual NIC's
listed + the real loopback....but no eth0....grrrrrr

lspci lists the device as:

09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5756ME
Gigabit Ethernet PCI Express

Any help?
