Restore VM as new one VM

[sub3xt1]

1. create VM 101, fresh centos 5.2 from iso,
a. name: server_a
b. ip: 192.168.8.1
2. i backup VM 101, result: vzdump-101.tgz
3. i restore by issued command:
# vzdump --restore vzdump-101.tgz 102

4. i correct environment on VM 102
a. hostname : server_b
b. ip : 192.168.8.2
c. try to edit mac address on proxmox server:
# nano /etc/qemu-server/102.conf
change value vlan0

5. from server_a : can ping outside network
6. from server_b : can ping outside network
7. from server_a and server_b : cannot ping each other.

firewall in centos?

both of the server give same clue:

# /etc/init.d/iptables status
Firewall is stop

should just work, just tested (with 5.3) exactly the way you described.
(I disabled firewall and se linux during install). check inside centos, use tcpdump to see whats going on.
