What is the **openSUSE way** for using VLAN 10 for my host and VLAN 20 for guest VMs with a bridged connection and KVM?

I have a fresh install of openSUSE Tumbleweed installed on my box. During the install process I said to install KVM Hypervisor and it defauled to a bridged connection (which is what I want).

My box is connected to a port on my switch that allows VLAN 10 and VLAN 20 with VLAN 20 being the default. I cannot change the settings of my switch/firewall/network.

Now I am trying to figure out the openSUSE way to:

  1. Configure the host to be VLAN 10
  2. Configure a VM to be VLAN 20

I’m going through all the screens in the settings but I cannot find anything.

Use ifcfg- to configure it conveniently in the manner you like. Create /etc/sysconfig/network/ifcfg-eth0 with something like this -

VLAN_ID="20"
VLAN_NAME="guest"

/etc/sysconfig/network/ifcfg-eth0.20

BOOTPROTO='dhcp'
STARTMODE='auto'
VLAN_ID='20'

And

/etc/sysconfig/network/ifcfg-eth0.10

BOOTPROTO='static'
IPADDR='192.168.10.2'
NETMASK='255.255.255.0'
STARTMODE='auto'
VLAN_ID='10'

Lastly, restart the network.

Double-check your guest and host interfaces; this is only a suggestion; it might or might not work perfectly.

I like openvswitch for what you describe. I’ve not used it on OpenSUSE yet, so I can’t really frame it in the context that you requested.
