Subject: [Xen-users] xenbr0, no peth0, problem with network configuration
Hello mailinglist,
i have a really strange problem.
Short summary:
I have a Server with Debian 4.0 (Etch) and a self-compiled Xen 3.1.
I am using bridged network, after compiling Xen 3.1 and restarting the system,
my "ifconfig" does not show any "peth0" and/or "vif0.0".
My ifconfig-output looks like this:
eth0 Link encap:Ethernet HWaddr MYMACADDRESS
inet addr:MYIPDADRESS Bcast:XX.XX.XX.XX Mask:XX.XX.XX.XX
inet6 addr: fe80::290:27ff:XXX:XXX/64 Scope:Link

collisions:0 txqueuelen:0
RX bytes:1344 (1.3 KiB) TX bytes:1344 (1.3 KiB)
xenbr0 Link encap:Ethernet HWaddr MYMACADDRESS
inet addr:MYIPADDRESS Bcast:XX.XX.XX.XX Mask:XX.XX.XX.XX
inet6 addr: fe80::290:27ff:XXX:XXX/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

collisions:0 txqueuelen:0
RX bytes:2895065662 (2.6 GiB) TX bytes:106636769 (101.6 MiB)
Look there, the IP-Address off eth0 and xenbr0 are identical.
The xenbr0-part of other Servers looks like this:
xenbr0 Protokoll:Ethernet Hardware Adresse FE:FF:FF:FF:FF:FF
UP BROADCAST RUNNING NOARP MTU:1500 Metric:1
RX packets:132 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
Kollisionen:0 SendewarteschlangenlÀnge:0
RX bytes:15558 (15.1 KiB) TX bytes:0 (0.0 b)
I have compiled Xen 3.1 correctly, because it is working great on other
(identical) systems. The config-files are from the Xen 3.1 package, nothing
changed.
Summary:
1) no peth0
2) no vif0.0
3) xenbr0 has IP, MAC (...) of eth0
A "ip r" shows this:
# ip r
NETWORKIP/30 dev xenbr0 proto kernel scope link src IPADDRESS
default via GATEWAYIP dev xenbr0
Other correct working systems say:
# ip r
NETWORKIP/30 dev eth0 proto kernel scope link src IPADDRESS
default via GATEWAYIP dev eth0
One more thing (look at the differences):
The "wrong" working systems says at dmesg:
Bridge firewalling registered
ADDRCONF(NETDEV_CHANGE): xenbr0: link becomes ready
device eth0 entered promiscuous mode
audit(1188330852.072:2): dev=eth0 prom=256 old_prom=0 auid=4294967295
xenbr0: port 1(eth0) entering learning state
xenbr0: topology change detected, propagating
xenbr0: port 1(eth0) entering forwarding state
eth0: no IPv6 routers present
xenbr0: no IPv6 routers present
###
ADDRCONF(NETDEV_CHANGE): xenbr0: link becomes ready
###
Look at the second line.
A correct working system says at dmesg:
Bridge firewalling registered
device vif0.0 entered promiscuous mode
audit(1188582851.818:2): dev=vif0.0 prom=256 old_prom=0 auid=4294967295
xenbr0: port 1(vif0.0) entering learning state
peth0: setting full-duplex.
xenbr0: topology change detected, propagating
xenbr0: port 1(vif0.0) entering forwarding state
peth0: Setting promiscuous mode.
device peth0 entered promiscuous mode
audit(1188582851.868:3): dev=peth0 prom=256 old_prom=0 auid=4294967295
xenbr0: port 2(peth0) entering learning state
xenbr0: topology change detected, propagating
xenbr0: port 2(peth0) entering forwarding state
vif0.0: no IPv6 routers present
peth0: no IPv6 routers present
eth0: no IPv6 routers present
I am using 100Mbit/s Intel NICs (PCI) on all my systems, "e100" Linux module.
There is something wrong, but i dont know what. :(
I hope you can help me.
Greetings,
Eduard
