I'm running OpenSUES 10.2 on a Pentium4 system where I have installed XEN and some guests. One of the guests is a (opensuse 10.2) firewall with 5 NICs. Since we have the limit of max 3 vifs' I'm exporting 2 with help of pciback. This works fine most of the time but sometimes the guest doesn't find the 2 direct exported ports ("lspci" returns nothing). It seems to never work if I reboot the guest and if I shutdown/create it works most of the time but not always.
Done a complete reinstall on a different system with different hardware, only os, config and problem is the same. The other system is a AMD server and the NICs are two dualport e100 where I did a fresh install of OpenSuSE 10.2 (this time x86_64, otherone was 32bit) and a new install of domU. After configuring the pciback and testing reboot I got the same as before, no extra ports after reboot of domU I did compare dmesg after reboto vs after cold boot and found two lines to be interesting root@reed:~$ diff -u dmesg_after_cold-boot dmesg_after_reboot-boot --- dmesg_after_cold-boot 2007-09-11 11:51:05.000000000 -0400 +++ dmesg_after_reboot-boot 2007-09-11 11:57:27.000000000 -0400 ... @@ -37,15 +37,13 @@ PCI: System does not support PCI PCI: System does not support PCI NET: Registered protocol family 2 -pcifront pci-0: Installing PCI frontend -pcifront pci-0: Creating PCI Frontend Bus 0000:00 IP route cache hash table entries: 4096 (order: 3, 32768 bytes) TCP established hash table entries: 16384 (order: 6, 262144 bytes) TCP bind hash table entries: 8192 (order: 5, 131072 bytes) ... Why doesn't "pcifront" gets loaded after reboot ??? What loads/initialize pcifront ? /ps
What can I do to make sure it always works? Where should I look for the problem ?
Config data: On the host (dom0) I have
root@dom0# cat /etc/modprobe.conf.local options pciback hide=(0000:03:02.1)(0000:03:03.1) install sunhme /sbin/modprobe pciback ; /sbin/modprobe --first-time --ignore-install sunhme

On the guest I configured the network ports with "yast lan" and after making the MAC static (it changed after each boot) it works whenever the bypassed nics are available.
root@domU:~# cat /etc/modprobe.conf.local options sunhme macaddr=0x08,0x00,0x20,0x00,0x00,0x49
Both host and guest runs a fully patched opensuse 10.2 -32bit
