libvirt (virt-manager + qemu) - How to get guest on same gateway?

Utini · 2016-06-28 09:34:14

Hello everyone,

I am running several guest OS on Arch in a qemu/kvm via libvirt (virt-manager).
They can connect to the internet just fine but are on a different gateway than my complete home-network.

E.g.
Router: 192.168.1.1
Arch laptop: 192.168.1.2
Phone: 192.168.1.3
Guest OS on Arch laptop: 192.168.122.14

How can I get the guest OS to be 192.168.1.x ? So it should communicate with the router as gateway, not the host machine?

Thanks !

@edit:
I can ping the router (192.168.1.1) from the guest OS. Changing the guest of networking from DHCP to manual won't give me a network access.

You need to set up bridged networking with qemu for your guests to be on the same subnet as your host.

There are already bridges created, or is this somethign different (vibr0 and vibr0-nic) ?

ip a

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: wlp6s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

    inet 192.168.122.1/24 scope global virbr0

4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel master virbr0 state DOWN group default qlen 1000
    link/ether 52:54:00:9d:54:07 brd ff:ff:ff:ff:ff:ff

I have tried creating a new bridge my self:
I am using "NetworkManager".
I create a interface in the GUI and selecte "bridge".
There I add a slave, but only with "VLAN" I cann add a WIFI as connection type, which won't connect to WIFI though.
Else I can only add Ethernet but not WIFI ?

Thanks !
