Hello All:
Here comes again after reboot and it lasts about an hour.
This time, my xen machine is unable to ping anywhere including other subnect
192.168.213 and external server like ping yahoo.com. Again, after reboot, thie
srror will be gone. How is it happended ?
Here is the xen debug log file. Maybe it will help debugging:

Hello All:
Sorry I need to add more in regarding this issue. The best term would be
"intermittent network hangs" as I see similar mails from the user
group.
Here is problem I found:
My xen domain 0 has ip: 192.168.204.225.
It can ping with other networks like 192.168.213 subnet and outside like
yahoo.com
but it can not ping 192.168.204 subnet except 192.168.204.1 which is the gateway
address.
Please help ....
Thanks

Hi:
I am able to run xend start and all my Guest OSs are running fine. However, it
is very unstable after a while. I can not ping other servers which used to be
working fine.
My netstat -nr output and my /etc/resolv.conf are fine also.
The only way to temparaily fix it is to reboot the server. But after a while, it
failed to ping other servers again.
Anyone has any suggestions how to troubleshoot ?
Thanks,
Jeremy
