Hi,
I have installed CentOS 5 with Xen on a new Dell SC440.
I have hidden a network interface in dom0 to pass it on to domU by adding
these lines in /etc/modprobe.conf:
options pciback hide=(04:00.0)
install tg3 /sbin/modprobe
pciback ; /sbin/modprobe --first-time --ignore-install tg3
CentOS builds pciback as a modules, so I could not add pciback.hide in the
grub configuration. I found the modprobe.conf setup in the XenSource wiki.
I am not sure if this part works fine: the nic is still visible via lspci in
dom0, although it is mentioned as disabled.
# lspci -vb
...
04:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5754 Gigabit
Ethernet PCI Express (rev 02)
Subsystem: Dell Unknown device 01df
Flags: fast devsel, IRQ 10
Memory at 00000000efbf0000 (64-bit, non-prefetchable) [disabled]
Capabilities: [48] Power Management version 3

Capabilities: [58] Vendor Specific Information
Capabilities: [e8] Message Signalled Interrupts: 64bit+ Queue=0/0

...
Also in dom0:
# ls -l /sys/bus/pci/drivers/pciback
total 0

--w------- 1 root root 4096 Apr 25 13:06 unbind
seems to suggest that the nic is really bound to pciback. It''s not
in /sys/bus/pci/drivers/tg3 anyway.
I then start a domU with the following configuration:
memory = 256
name = "CentOSFileserverLVM"
vcpus = 2
vif = [ ''mac=aa:cc:00:00:00:02, bridge=xenbr0'' ]
pci = [ ''04:00.0'' ]
disk = [ ''phy:base/fwroot,xvda,w'',
''phy:base/fwhome,xvdb1,w'',
''phy:base/fwvar,xvdb2,w'',
''phy:base/fwbackup,xvdb3,w'',
''phy:base/fwswap,xvdb4,w'' ]
bootloader="/usr/bin/pygrub"
bootargs="/dev/base/fwroot"
root = "/dev/xvda2"
vfb = [ ''type=vnc,
vnclisten=0.0.0.0,
vncunused=1,
display=localhost:12.0'' ]
This boots fine, but I don''t find the nic in domU. lspci returns
absolutely
nothing. From reading messages on different forums (like this one:
http://www.vdr-portal.de/board/thread.php?threadid=60330), I gather the boot
messages for domU should contain some entries like > pcifront pci-0: Installing PCI frontend
> pcifront pci-0: Creating PCI Frontend Bus 0000:03
and > PCI: Enabling device 0000:03:04.0 (0000 -> 0003)
or similar.
It seems this is not the case for my setup. I have no idea what goes wrong and
why. Did anybody else get stuck at this point, and managed to fix it ?
