I've got a Digium PCI telephone card that I'm trying to use with an AsteriskNow guest, on a CentOS 5.2 host. I've tried setting up the pciback stuff, and think I've done it right, but the card does not show up in the guest. I'm obviously missing something, so any help (including ways to debug this!) would be greatly appreciated.
Here's some more info:
The guest is fully virtualized, so I'm assuming that nothing should need to be configured within the guest.
On the host, the card shows up as:
[root@xenhost bus]# lspci | grep Digium 07:01.0 Ethernet controller: Digium, Inc. Unknown device 8005 (rev 11)
I think the pciback is set up properly. When I load the module, the /sys/bus/pci/drivers/pciback/ is created, and everything looks the way I think it should:
[root@xenhost pciback]# pwd ; cat slots ; file 0000:07:01.0
/sys/bus/pci/drivers/pciback 0000:07:01.0 0000:07:01.0: symbolic link to `../../../../devices/pci0000:00/0000:00:02.0/0000:01:00.3/0000:07:01.0'
This shows up in /var/log/messages:
Oct 24 16:34:58 xenhost kernel: pciback 0000:07:01.0: seizing device Oct 24 16:34:58 xenhost kernel: PCI: Enabling device 0000:07:01.0 (0000 -> 0003) Oct 24 16:34:58 xenhost kernel: ACPI: PCI Interrupt 0000:07:01.0[A] -> GSI 24 (level, low) -> IRQ 20 Oct 24 16:34:58 xenhost kernel: ACPI: PCI interrupt for device 0000:07:01.0 disabled
Here is my xen config file, with the PCI line at the end:
name = "asterisk_now" uuid = "02f476ce-7a98-e58c-f715-0bb28a3c6c3d" maxmem = 2048 memory = 1024 vcpus = 1 builder = "hvm" kernel = "/usr/lib/xen/boot/hvmloader" boot = "c" pae = 1 acpi = 1 apic = 1 localtime = 0 on_poweroff = "destroy" on_reboot = "restart" on_crash = "restart" device_model = "/usr/lib/xen/bin/qemu-dm" sdl = 0 vnc = 1 vncunused = 1 keymap = "en-us" disk = [ "phy:/dev/datafarm/asterisk_now,hda,w", ",hdc:cdrom,r" ] vif = [ "mac=00:16:3e:6c:ae:c2,bridge=xenbr0" ] serial = "pty" pci = [ "07:01.00" ]
(In the scattered bits of documentation I've found on this topic, I've seen a couple of different formats for specifying the PCI, including "pci = [ "0000:07:01.00" ] and "7,1,0". None of them seemed to work either.
My virtual AsteriskNow machine is not yet running (and I've tried restarting xend at this point), but when I start the machine, no card is visible:

Thanks in advance for any assistance!
