Hello everybody,
I'm using FC7 and my server (IntelXeonQuad 64bit) provides 2 NICs. With virsh-install I installed a (32bit RHEL3) HVM. Until here everything runs fine. When installing FC7, NIC1(eth0) got a public IP and NIC2(eth1) got a private one. When installing the HVM (RHEL3) only one NIC(eth0) exists, which got a public IP. The problem is that I also want the HVM to have a second NIC connected to my private network (as in Dom0).
By default only one bridge (virbr0) is created. brctl show gives: eth0 8000.003048322dea no vif3.0 tap0 peth0 virbr0 8000.000000000000 no
How can I create a second one for (p)eth1 ? By the way where does tap0 come from and what is it good for?
Thanks for any help. Jens

My first thought, Does swapping the wires fix this? Crude maybe, but it should work.
Then I thought "oh, you might need to attack ifcfg-eth0 and ifcfg-eth1 to delete the MAC addresses."
Now, I'm thinking that running system-config-network to swap the definitions so that eth1 is the gateway to the world and the other's private.
That should work, and continue to work over time.

I had half-hearted fiddle with opensuse 10.2 on my laptop (wireless and wire, i want the guest on the wireless) and didn't get anywhere.
