Okay I'm running debian sqeeze (testing) which bridge-utils 1.4-5 and kernel 2.6.30 amd64 variant This is running on a new Dell Poweredge R610 with dual dual bnx2 nics 01:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20) 01:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20) 02:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20) 02:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20) I have a bridge I'm trying to create for kvm. eth0 is my local access so it's just a now nic with dhcp connected to my lan, which works no problem. Then I created a bridge called prot0 and set it to manual, and added eth1 (also set to manual) to it. When I start my kvm guest it creates a tap interface called vnet0 also without an ip and adds it to the bridge. My guest OS then has eth0 which has an ip on static. So at this point this is what things look like on the host box. brctl show bridge name bridge id STP enabled interfaces prot0 8000.0022195e3239 no eth1 vnet0 brctl showmacs prot0 port no mac addr is local? ageing timer 1 00:22:19:5e:32:39 yes 0.00 2 ba:ea:0d:0f:8b:aa yes 0.00 on the guest I start a ping to anything, google.com for this example. And I set tcpdump -i prot0 or vnet0 and I see the arp request for the dns servers but no reply. Which looks like this. 09:54:43.444533 ARP, Request who-has dns1.domain.tld tell rdns.guestdomain.tld, length 28 09:54:44.440585 ARP, Request who-has dns1.domain.tld tell rdns.guestdomain.tld, length 28 09:54:45.440587 ARP, Request who-has dns1.domain.tld tell rdns.guestdomain.tld, length 28 But if I do a tcpdump -i eth1 I see nothing at all. here is my /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp auto prot0 iface prot0 inet manual bridge_ports eth1 bridge_stp off bridge_maxwait 5 And my lsmod Module Size Used by ip6table_filter 3904 0 ip6_tables 18928 1 ip6table_filter iptable_filter 3776 0 ip_tables 17392 1 iptable_filter x_tables 22440 2 ip6_tables,ip_tables tun 13984 2 kvm_intel 47368 4 kvm 158904 1 kvm_intel bridge 48256 0 stp 2868 1 bridge ext2 62816 1 loop 15980 0 snd_pcsp 10588 2 snd_pcm 78504 1 snd_pcsp snd_timer 21824 1 snd_pcm snd 63912 7 snd_pcsp,snd_pcm,snd_timer soundcore 7984 1 snd snd_page_alloc 10000 1 snd_pcm joydev 10992 0 psmouse 42172 0 serio_raw 5844 0 dcdbas 8560 0 evdev 10448 13 button 6512 0 processor 40160 8 ext3 122864 1 jbd 48168 1 ext3 mbcache 8804 2 ext2,ext3 dm_mod 59384 6 sg 24024 0 usbhid 37328 0 hid 41376 1 usbhid sr_mod 15908 0 cdrom 34344 1 sr_mod ide_pci_generic 4964 0 ide_core 105120 1 ide_pci_generic ses 6528 0 ata_generic 5924 0 sd_mod 33720 3 uhci_hcd 22208 0 crc_t10dif 2096 1 sd_mod enclosure 9120 1 ses ata_piix 25124 0 megaraid_sas 34396 2 libata 175500 2 ata_generic,ata_piix scsi_mod 158784 6 sg,sr_mod,ses,sd_mod,megaraid_sas,libata ehci_hcd 33820 0 bnx2 62712 0 thermal 15936 0 fan 5240 0 thermal_sys 16448 3 processor,thermal,fan /proc/sys/net/bridge# for i in *; do echo -n $i; echo -n ": ";cat $i; done bridge-nf-call-arptables: 0 bridge-nf-call-ip6tables: 0 bridge-nf-call-iptables: 0 bridge-nf-filter-pppoe-tagged: 0 bridge-nf-filter-vlan-tagged: 0 I just don't understand how it can be getting to prot0 (my bridge) but no be seen on eth1 which is a bridge member. Any help or anything I can try would be most helpful, Thanks in advance. --- TS http://southofheaven.org/ Chaos is the beginning and end, try dealing with the rest. _______________________________________________ Bridge mailing list Bridge@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/bridge
