I just installed Fedora 13 on my ESX box.I have Fedora 13 Machine which was early having 1 network adapter.I added a new Interface type: e1000 to this VM.Now,My ifconfig says:

Code:

[root@fedora-13 ~]# ifconfig

Whenever I restart the network it says:

Code:

[root@fedora-13 ~]# service network restart

All i was trying to provide IP to eth0 and eth1 through dhcp.
is it possible to provide two IP address to eth0 and eth1 both through DHCP.

Any number of nic's either real or virtual could get a single IP assigned by dhcp.

It may be possible in the actual reference that a second IP could be offered also but I have never seen it implemented.

I'd suggest that you re-install the OS from scratch and see if it fails with the two nic's present at install time.

Kind of hard to isolate a beta install to some feature or bug.

Also if both are add on cards, move the cards order in the pci slots too.

Also maybe try disabling eth1

Code:

ifconfing eth1 down

and see if you can get an IP on eth2

I have a box right now in a production environment that gives me access to the internal network on eth1 and i test/config other modem/routers as well as pass external traffic on eth2 seeing both have different gateways i prefer to static the IP on eth2 this may also prove as a solution to you if DHCP is not a necessity for your task.

in my case

Code:

ifcfg eth2 192.168.15.2

hope you get this working

Oh, instead of stop maybe simply try to renew lease.
