Network interface # swapped from configuration after power-on

[LejinDu]

Hi,

In vCD 1.5, I tried to create a vApp based on Ubuntu 10.04. Before power-on, I configured 2 network interfaces on the vApp: eth0 or NIC 0 (named "Internet_A...") = x.x.100.1, eth1 or NIC 1 (named "AA_LAN...") = x.x.111.1. After power-on, sometimes (roughly 50% times) the network interface # would swapped and become: eth0 (named "AA_LAN...") = x.x.111.1, eth1 (named "Internet_A...") = x.x.100.1. Is the swap related to naming (alphabet order)? Does this only happen to Ubuntu based vApp? What should I do to stop the swap?

Thanks for any help.

Did more tests for this network interface # swap problem, it happened on different network configurations. Here are 2 types of network configurations with heavy tests:

1) One vApp with one VM (Ubuntu 10.04) only; this VM/vApp had two network interfaces, one for external Org Network and the other for internal Org Network. Swap happened randomly.

2) One vApp with multiple VMs, one VM (Ubuntu 10.04) had two network interfaces, one for external Org Network and the other for vApp Network. Swap happened randomly.

Really need to sovle this problem as soon as possible. Work around solutions will be fine as well.

Appreciate any suggestions.

Thanks.
