[Xen-devel] Question about network-route

[wei huang <huanwei@xxxxxxxxxxxxxxxxxx>]

Hi,

I saw in file /etc/xen/xend-config.sxp that I also have the choice to use
network-route to configure the network. I have troubles using veth0 so I
would like to give it a shot.

I saw some of instruction given in the mailing list:
http://lists.xensource.com/archives/html/xen-devel/2005-01/msg00368.html

I strictly follow it: modify the xend-config.sxp, configuration script and
start domu. (I didn't change the network-route and vif-route scripts
though)

But it seems that DomU is still trying to get ip from dhcp. It stops at
determine eth0 ip address for quite a long time and quits with fail.
Do I have to change something at /etc/sysconfig/network-script/ifcfg-eth0
in my domU disk image? If so, I guess it should not be booted with dhcp.
But what should my static ip, netmask, default gateway be?

Here I tried to change the static ip to "1.2.3.4" (what ever I specify in
the script) and mask to be 255.255.255.255 but leave the gateway blank.
Now DomU got its ip during boot time cannot connect outside.

I check dom0's route table after domU boots, it seems that 1.2.3.4 is
there:
Kernel IP routing table
tination     Gateway         Genmask         Flags Metric Ref    Use Iface
1.2.3.4         *               255.255.255.255 UH    0      0      0 vif1.0
9.2.72.0        *               255.255.255.128 U     0      0      0 eth0
169.254.0.0     *               255.255.0.0     U     0      0      0 eth0
default         lab001.watson.i 0.0.0.0         UG    0      0      0 eth0

And DomU's routing table:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
169.254.0.0     *               255.255.0.0     U     0      0        0 eth0
default         *               0.0.0.0         U     0      0        0 eth0

Dom0 can ping 1.2.3.4 but cannot ssh. DomU cannot access outside, even use
ping.

Am I miss something here? I really got stuck here so any suggestions will
be helpful.

Thank you very much!

Regards,
Wei Huang
