I tried to hide my 2nd NIC too from Dom0 using Xen 3.2.1 with the appropriate entries in modprobe.conf but it didnt work. I reverted back to using Xen 3.1 where it worked fine. I'd like to know how this goes with 3.2.1.

Hi,
Have just brought a Digium TDM400P card for my Asterisk server but appear to be having trouble getting it to be hidden from DOM-0. Here is what dmesg shows :-
pciback 0000:02:07.0: Driver tried to write to a read-only configuration space field at offset 0x44, size 2. This may be harmless, but if you have problems with your device:
1) see permissive attribute in sysfs
2) report problems to the xen-devel mailing list along with details of your device obtained from lspci.
PCI: Enabling device 0000:02:07.0 (0000 -> 0003)
ACPI: PCI Interrupt 0000:02:07.0[A] -> GSI 26 (level, low) -> IRQ 20
ACPI: PCI interrupt for device 0000:02:07.0 disabled
pciback: vpci: 0000:02:07.0: assign to virtual slot 0
PCI: Enabling device 0000:02:07.0 (0000 -> 0003)
and from the lspci :-
02:07.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface
Subsystem: Unknown device b100:0001
Flags: bus master, medium devsel, latency 64, IRQ 20
I/O ports at a800 [size=256]
Memory at fc7ff000 (32-bit, non-prefetchable) [size=4K]
Capabilities: [40] Power Management version 2
In my rc.local I have the following :-
modprobe pciback
sleep 2
SLOT=0000:02:07.0
echo -n $SLOT > /sys/bus/pci/drivers/pciback/new_slot
echo -n $SLOT > /sys/bus/pci/drivers/pciback/bind
Does this look okay ? or should I contact the devel list ?
Regards,
