Re: [Xen-users] Guest Network Some can Ping, Some can't Ping



Hi Igor,

Thanks for your advice! And /32 is really good idea. I never know that.

Ye, I can ping guest now. It seems the eth0 is the problem, hardware problem I guess. ..

Thanks a lot!

It is 6 pm here. I get to go home:)

Cheers!

Hi Igor,

Thanks for ur reply!

Ye, you are right. I changed the ip for eth1 to 121 now.  Thanks.


It's better now but you've better not use IP addresses from same IP-network on several interfaces.

If you necessarily must use IP-addresses from one IP-network, it's better to specify netmask /32 on all of them except one.


Also I create another xen bridge for eth1 by using:

#!/bin/sh
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0
"$dir/network-bridge" "$@" vifnum=1

Then change /etc/xen/xend-config.sxp with the following (network-script my-network-script).


Then I assign the guest1 to xenbr1. You know what, it seems fine now.
Now I can ping eth0 and eth1 from any pc and looks great. what 's the reason????
it doesn't explain anything, does it?



You talk about eth0 and eth1 of domain 0, but can you ping guests?


I attach the ifconfig and brctl show output here, Thanks again, Igor!


Thank you for commands output.
It looks good
