I am using Xen 4.0 with Ubuntu 9.10amd64. I have 4 guests configured
alike. I configured the network using NAT, from 10.0.0.5- 10.0.0.8 for
dom1-dom4 respectively

I tried to install emacs, but it hung up. So  I wanted to troubleshoot
it.

I pinged google from all four domUs, and interestingly, two of them hung
up after 30 seconds.

----------DOM1-------
64 bytes from pv-in-f104.1e100.net (72.14.213.104): icmp_seq=31 ttl=52
time=12.3 ms

>From 10.0.0.5 icmp_seq=82 Destination Host Unreachable

----------DOM2-------
64 bytes from pv-in-f103.1e100.net (72.14.213.103): icmp_seq=36 ttl=52
time=12.5 ms

>From 10.0.0.6 icmp_seq=63 Destination Host Unreachable

----------DOM3-------
64 bytes from pv-in-f103.1e100.net (72.14.213.103): icmp_seq=418 ttl=52
time=12.4 ms


----------DOM4-------
64 bytes from pv-in-f104.1e100.net (72.14.213.104): icmp_seq=233 ttl=52
time=12.5 ms

============================
Is this some kind of bug? I get the issue in different domains in
different trials..!?!


thanks
Sriram
