Hi all,
I have 3 guests (2-RHEL4 and 1 RHEL6) and have some issues regarding networking between them. The 2 RHEL4 system's use default bridge virbr0 and get ip's of range 192.168.122.0/24 (192.168.122.207, 192.168.122.167)
I created another bridge (virbr1) with NAT forwarding (no dhcp). The network i choose was 192.168.100.0/24. And the third system (RHEL6) was assigned static ip-addres 192.168.100.101,
From the RHEL6 system which uses virbr1 is able to ping systems in 192.168.122.0/24 series , but guest systems in 192.168.122.0/24 are not able to ping RHEL6 system (in virbr1) network.
From the RHEL4 guests i am able to ping the gateway ip's (192.168.122.1, 192.168.100.1) , but not the RHEL6 system
That's correct behavior, because the networks are in different ranges they need to have a way to talk to each other, either via a gateway or fixed routing.
ok
btw, Why do you need your hosts in separate networks?
I have a special requirement where i need guests from different networks (subnets) to need to communicate each other. You may want to check this page on libvirt networking.
