I''m proposing to checkin the attached new /etc/xen/network script.
I''m
hoping it will be more robust to the various network startup problems
people have seen by using vendor ifup/ifdown scripts.
Please can people try it out, particularly if you had problems with the
old script.
If the script does fail for you, /var/log/xend.debug may have some
useful info. Please try to dig around to try and understand what has
gone wrong. I''ve attached the output of ifconfig before and after
starting xend for comparison.
We''re still awaiting patches to enable interfaces other than eth0 to be
specified in xend-config.sxp, so if you''re primary interface is eth1
edit the default ''netdev'' parameter at the top of the file.
Thanks,
Ian

I tried the new network script on a couple of my boxes. I got it working
fine with RHEL4 box (x86-32). But somehow it did not work for my SLES9 SP2
boxes (x86-32 and x85-64). The output of ifconfig on RHEL4 box looks right
to me. But the ones on SLES9 SP2 does not. Here are the steps I used and
how they looked like:
1) Right after I start xend:
bl2-1:~ # ifconfig

collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
2) Right after I issued command "xm create vm1", it became:
bl2-1:~ # ifconfig

3) The network was not pingable on domU after domU booted up.
4) Then I shutdown domU, and the output of ifconfig on domU went back to 1)
5) If I switch back to the old network script, network works fine on both
dom0 and domU.
Could this have something to do with the bridge-utils-0.9.6-121.1 which
SLES9 SP2 uses?

Both this two machines are IBM blades. Eth1 is used for network connection
and eth0 is used for SOL (Serial Over LAN) connection on these blades. I
did change eth0 to eth0 in network script.
I will try to collect more info on non-blade box using eth0 later.

Do you still have network connectivity in dom0 after starting xend?
Please post the output of the following commands before and after
starting xend:
ifconfig
brctl show
I see your setup has an eth1. Does it also have an eth0? Which do you
want on xen-br0? Have you edited the default netdev line at the top of
the new network script?
Thanks,
Ian

Both this two machines are IBM blades. Eth1 is used for network connection
and eth0 is used for SOL (Serial Over LAN) connection on these blades. I
did change eth0 to eth0 in network script.
I will try to collect more info on non-blade box using eth0 later.

Do you still have network connectivity in dom0 after starting xend?
Please post the output of the following commands before and after
starting xend:
ifconfig
brctl show
I see your setup has an eth1. Does it also have an eth0? Which do you
want on xen-br0? Have you edited the default netdev line at the top of
the new network script?
Thanks,
Ian

On the machine with eth0, please send the relevant bit of

Also, what happens if you do:
ifdown eth0
ifup eth0

Argghh. There''s a really stupid bug in the script.
Please edit the following line:
-if ! ifdown ${netdev} ] ; then
+if ! ifdown ${netdev} ; then
I''m not sure that the extraneous '']'' is actually the
problem, though.
Please can you add a `which ifdown` just before that line.
Thanks,
Ian

I modified the script based on what you suggested. Now after starting xend,
there is nothing changed in the output of ifconfig:

Switching back to the original network script, the network works again.

OK, this is interesting. It''s the same symptoms as the old script.
It looks like peth0 is receiving packets. Please confirm this with:
tcpdump -i peth0
What''s odd is that there''s no xen-br0 showing up in ifconfig.
I''d expect
to see something like:
xen-br0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:949 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:54097 (52.8 Kb) TX bytes:0 (0.0 b)
Can you post the output of ''brctl show''. You should see:
[root@commando-0 root]# brctl show
bridge name bridge id STP enabled interfaces
xen-br0 8000.feffffffffff no vif0.0
peth0
Also, please can you try replacing the following lines:
- add_to_bridge ${bridge} vif0.0
- add_to_bridge ${bridge} p${netdev}
+ brctl addif ${bridge} vif0.0
+ brctl addif ${bridge} p${netdev}
and earlier:
+ create_bridge ${bridge}
- brctl addbr ${bridge}

ian,
as the discussion in this thread, service os netwok will break after
xend start.
this simple patch can work on my mahine.
but strange error still occur in xend.log and xend start takes more time
with ifdown/ifup.

I, too, am having network related issues. I am now seeing this problem
on a FC3 box, which previously had worked just fine. The networking is
working fine before I enter ''xend start''. No changes are made
to the
network-bridge script that comes with the source, and the machine has
only only nic, eth0.
ifconfig before ''xend start'':

xen-br0 is up, but networking is dead. This is different from the previous
issues where xen-br0 was not coming up, but when
started manually networking resumed.
On 2 other machines, networking is up and working, Dom0 has networking running
correctly, but when I start a domU, it does not
have networking. I have 3 similar machines, only one of which has a domU with
working network; the other two don''t, even though
they have very similar setups. This *may* end up being a setup issue (although
these same setups worked before), but I can''t figure out what that
could be--everything looks
like it is supposed to be.

What kind of network card is this? The TX/RX counters for the new eth0 are non zero. Are they going up? In what whay does networking not work? Can you use tcpdump on eth0 to determine whether packets from the outside world are arriving. If not, what about peth0? (Bare in mind that if you only have one-way connectivity the only packets you're see are arps, not icmp pings or anything else) Ian> ifconfig before 'xend start': > > [root@dbarrera ~]# ifconfig > eth0 Link encap:Ethernet HWaddr 00:0D:60:F0:C5:C8 > inet addr:9.53.94.235 Bcast:9.53.94.255 Mask:255.255.255.0 > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:99 errors:0 dropped:0 overruns:0 frame:0 > TX packets:88 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:1000 > RX bytes:12299 (12.0 KiB) TX bytes:11426 (11.1 KiB) > Base address:0x2000 Memory:e8100000-e8120000 > > lo Link encap:Local Loopback > inet addr:127.0.0.1 Mask:255.0.0.0 > UP LOOPBACK RUNNING MTU:16436 Metric:1 > RX packets:26 errors:0 dropped:0 overruns:0 frame:0 > TX packets:26 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:2216 (2.1 KiB) TX bytes:2216 (2.1 KiB) > > [root@dbarrera ~]# brctl show > bridge name bridge id STP enabled interfaces > [root@dbarrera ~]# > > when 'xend start' is entered, these messages appear on console: > store_evtchn = 16 > XENBUS xs_read_watch: 0 > > ifconfig AFTER 'xend start'eth0 Link encap:Ethernet > HWaddr 00:0D:60:F0:C5:C8 > inet addr:9.53.94.235 Bcast:9.53.94.255 Mask:255.255.255.0 > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:380 errors:0 dropped:0 overruns:0 frame:0 > TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:28046 (27.3 KiB) TX bytes:426 (426.0 b) > > lo Link encap:Local Loopback > inet addr:127.0.0.1 Mask:255.0.0.0 > UP LOOPBACK RUNNING MTU:16436 Metric:1 > RX packets:26 errors:0 dropped:0 overruns:0 frame:0 > TX packets:26 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:2216 (2.1 KiB) TX bytes:2216 (2.1 KiB) > > peth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF > inet addr:9.53.94.235 Bcast:9.53.94.255 Mask:255.255.255.0 > UP BROADCAST RUNNING NOARP MULTICAST MTU:1500 Metric:1 > RX packets:501 errors:0 dropped:0 overruns:0 frame:0 > TX packets:111 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:1000 > RX bytes:44601 (43.5 KiB) TX bytes:12036 (11.7 KiB) > Base address:0x2000 Memory:e8100000-e8120000 > > vif0.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:3 errors:0 dropped:0 overruns:0 frame:0 > TX packets:380 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:426 (426.0 b) TX bytes:28046 (27.3 KiB) > > xen-br0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:375 errors:0 dropped:0 overruns:0 frame:0 > TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:22208 (21.6 KiB) TX bytes:0 (0.0 b) > > [root@dbarrera ~]# brctl show > bridge name bridge id STP enabled interfaces > xen-br0 8000.feffffffffff no peth0 > vif0.0 > > xen-br0 is up, but networking is dead.

Please can you do a ''netstat -rn'' before and after.I should point out that the new network-bridge script appears to have cured the original problem on the SLES 9 boxes; at least xen-br0 is coming up and Dom0 retains networking on those boxes. On the FC3 box: before:[root@dbarrera ~]# netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 9.53.94.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 9.53.94.1 0.0.0.0 UG 0 0 0 eth0> What kind of network card is this?Intel 82541EI Gigabit Ethernet Controller (Copper)> > The TX/RX counters for the new eth0 are non zero. Are they going up? > In what whay does networking not work?I cannot connect to or from the outside (ssh, ping, nfs mounts, etc).> Can you use tcpdump on eth0 to determine whether packets from the outside world are arriving.It seems that packets from the outside world are coming in. I entered ''tcpdump -n -i eth0 host 9.53.94.235'' then when I tried to ssh from the other machine, it shows up on the tcpdump. But the ssh session is never established. Ping shows up as well.> If not, what about peth0?Same.> (Bare in mind that if you only have one-way connectivity the only packets you''re see are arps, not icmp pings or anything else) > > Ian > > > ifconfig before ''xend start'': > > > > [root@dbarrera ~]# ifconfig > > eth0 Link encap:Ethernet HWaddr 00:0D:60:F0:C5:C8 > > inet addr:9.53.94.235 Bcast:9.53.94.255 Mask:255.255.255.0 > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:99 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:88 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:1000 > > RX bytes:12299 (12.0 KiB) TX bytes:11426 (11.1 KiB) > > Base address:0x2000 Memory:e8100000-e8120000 > > > > lo Link encap:Local Loopback > > inet addr:127.0.0.1 Mask:255.0.0.0 > > UP LOOPBACK RUNNING MTU:16436 Metric:1 > > RX packets:26 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:26 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:0 > > RX bytes:2216 (2.1 KiB) TX bytes:2216 (2.1 KiB) > > > > [root@dbarrera ~]# brctl show > > bridge name bridge id STP enabled interfaces > > [root@dbarrera ~]# > > > > when ''xend start'' is entered, these messages appear on console: > > store_evtchn = 16 > > XENBUS xs_read_watch: 0 > > > > ifconfig AFTER ''xend start''eth0 Link encap:Ethernet > > HWaddr 00:0D:60:F0:C5:C8 > > inet addr:9.53.94.235 Bcast:9.53.94.255 Mask:255.255.255.0 > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:380 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:0 > > RX bytes:28046 (27.3 KiB) TX bytes:426 (426.0 b) > > > > lo Link encap:Local Loopback > > inet addr:127.0.0.1 Mask:255.0.0.0 > > UP LOOPBACK RUNNING MTU:16436 Metric:1 > > RX packets:26 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:26 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:0 > > RX bytes:2216 (2.1 KiB) TX bytes:2216 (2.1 KiB) > > > > peth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF > > inet addr:9.53.94.235 Bcast:9.53.94.255 Mask:255.255.255.0 > > UP BROADCAST RUNNING NOARP MULTICAST MTU:1500 Metric:1 > > RX packets:501 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:111 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:1000 > > RX bytes:44601 (43.5 KiB) TX bytes:12036 (11.7 KiB) > > Base address:0x2000 Memory:e8100000-e8120000 > > > > vif0.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:3 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:380 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:0 > > RX bytes:426 (426.0 b) TX bytes:28046 (27.3 KiB) > > > > xen-br0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:375 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:0 > > RX bytes:22208 (21.6 KiB) TX bytes:0 (0.0 b) > > > > [root@dbarrera ~]# brctl show > > bridge name bridge id STP enabled interfaces > > xen-br0 8000.feffffffffff no peth0 > > vif0.0 > > > > xen-br0 is up, but networking is dead.

I think what is happening is that the routes are going down, but to bring up peth0 again, we only do a ip link set peth0 up, which creates an interface route, but does not automatically generate a default route (since we aren''t transferring routes in this case).

Just synced with the correct script. One potential issue is the link set of peth0, which creates an interface route for peth0, at least on my currently broken box. The ifup of eth0 (veth0) will try to add a duplicate route for the primary subnet via eth0. Can''t validate or test any of the above since my box is crashing at boot, unrelated issue, will dig into this tmrw further when I get onto a box.. This in no way explains why having the del_addrs works for him when it''s prior to the link set up of peth0 (??), so this isn''t the fatal error.

What I don''t understand is why the link set up on peth0 causes an address to appear. I thought it might be an old address from when it was eth0 getting resurected, hence the line I added. I wander if ''ifconfig ${netdev} 0.0.0.0 down'' would work better?

Ian Pratt wrote:> I thought it might be an old address from when it was eth0 getting > resurected, hence the line I added. I wander if ''ifconfig ${netdev} > 0.0.0.0 down'' would work better?One of the advantages to using the ifup/ifdown distro interface manipulation scripts is to also have them take care of the other things (radvd restart, ipv6, ipsec issues, ifup/down*local* scripts which might be doing other things when interfaces go up and down). We aren''t taking care of a lot of the other subsystems here, and I see the advantage in using the system configuration scripts as far as possible. The ifconfig line above would work in most cases, though, works for me ;). thanks, Nivedita _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

You''re not also setting the address via an ip= line on the kernel command line, or via an initrd? What''s the contents of your ifcfg-eth0 file?

We''ll test later today.I am assuming the new network-bridge script is in the latest hg pull as of this morning. It seems to have fixed the problems on the SLES 9 boxes; however, I seem to be having trouble on the FC3/4 boxes; the domUs on those boxes cannot connect to the network, even though they seem to be setup correctly and both worked previously.

Don''t know what was different this time, but it is working. So, I have 2 SLES 9 SP2 boxes and an FC4 box booted to Dom0 and with functional DomUs now. The FC3 is the dhcp box, and maybe the dhcp server is out of addresses.> > Please post the xend.log > > Ian >-- Regards, David F Barrera Linux Technology Center Systems and Technology Group, IBM "The wisest men follow their own direction.
