Hi all, I am trying to configure a Dom U to act as a firewall and therefore I need to pass one of the two ethernet cards to the Dom-U. I configured the Xen kernel to build pciback as part of the kernel instead of module and I am passing the hide option via boot parameters. /boot/grub/menu.lst title Xen 3.3.0 / Debian GNU/Linux, kernel 2.6.18.8-xen root (hd0,1) kernel /xen-3.3.0.gz console=tty0 module /vmlinuz-2.6.18.8-xen root=UUID=ba92848e-0fd0-4f78-ae59-c77c1fb\ 7d88a ro console=tty0 pciback.permissive pciback.hide=(0000:02:00.0) module /initrd.img-2.6.18.8-xen I boot the pv machine via pygrub and I am able to see the ethernet device in Dom U as follows: Dom-U#lspci 02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5722 Gigabit Ethernet PCI Express When I load the driver the eth device comes up: Dom-U#modprobe tg3 eth1: Tigon3 [partno(BCM95722) rev a200 PHY(5722/5756)] (PCI Express) 10/100/1000Base-T Ethernet 00:1e:c9:53:53:a3 eth1: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] WireSpeed[1] TSOcap[1] eth1: dma_rwctrl[76180000] dma_mask[64-bit] However when I try to bring up the interface using #ifup eth1 I get the following: get owner for dev 0 get 1 error enable msi for guest 1 status fffffff0 SIOCSIFFLAGS: Function not implemented Sending on LPF/eth1/00:1e:c9:53:53:a3 Sending on Socket/fallback receive_packet failed on eth1: Network is down DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 4 send_packet: Network is down Dom-U dmesg shows the following: pci frontend enable msi failed for dev 2:0 pci frontend enable msi failed for dev 2:0 pci frontend enable msi failed for dev 2:0 pci frontend enable msi failed for dev 2:0 pci frontend enable msi failed for dev 2:0 pci frontend enable msi failed for dev 2:0 Dom-0 dmesg shows: PCI: Enabling device 0000:02:00.0 (0000 -> 0002) ACPI: PCI Interrupt 0000:02:00.0[A] -> Link [LNK2] -> GSI 19 (level, low) -> IRQ 16 PCI: Setting latency timer of device 0000:02:00.0 to 64 pciback 0000:02:00.0: Driver tried to write to a read-only configuration space field at offset 0x68, size 4. 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. get owner for dev 0 get 1 error enable msi for guest 1 status fffffff0 get owner for dev 0 get 1 error enable msi for guest 1 status fffffff0 get owner for dev 0 get 1 error enable msi for guest 1 status fffffff0 get owner for dev 0 get 1 error enable msi for guest 1 status fffffff0 Your help will be greatly appreciated.
