hello all,
I have been trying to set-up bridged network with VLAN and not able to
succeed as many tutorials address only single NIC.
I am trying to setup 2 guests (backtrack instance) each guest has NIC1 and
NIC2. following is snippet for guest1
I am not able to get 192.168.0.2 address back on guest eth0.
VIRT-MANAGER GUI :
guest1-lan details radio button
left side panel
NIC1 ------------------> Virtual Network Interface
Source Device : Virtual Network "default" NAT
Device Model : Hypervisor default
MAc Address : xxxxxxxxxxxxxx
NIC2 ------------------> Virtual Network Interface
Source Device : Specify Shared Device Name
Bridge name : guest1-lan
Device Model : virto
MAc Address : xxxxxxxxxxxxxx
HOST MACHINE :
brctl show has br0 for bridge
and virbr0 with 192.168.122.x address (created by default virtual network
NAT)
