Interestingly, I can ping the other host..

[root@vh02 ~]# ping 192.168.41.21

PING 192.168.41.21 (192.168.41.21) 56(84) bytes of data.

64 bytes from 192.168.41.21: icmp_seq=1 ttl=64 time=0.387 ms

Both hosts are XCP 1.0 and plugged directly into the same physical switch.

Just not route anything to it..

Hmm, interesting! I'd go for the other obvious, and that is iptables. Checking both filter and nat chains.

Have tcpdump or tshark running on vh01 and see if the packets are arriving to the machine.

It could be an ACL of XCP which denies connectivity with an ICMP "destination unreachable", however I am not familiar with XCP but I'm sure someone else on the list can chime in for you.

May the ping be with you ..
