Description of Issue/Question

I would like to give some kvm guests direct network access. manual configuration of a vm guest works and creates the following (eno1 is main interface):

<interface type='direct'>
<mac address='52:54:00:f0:8a:3a'/>
<source dev='eno1' mode='bridge'/>
<target dev='macvtap1'/>
<model type='virtio'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
</interface>

65536: macvtap1@eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 500
    link/ether 52:54:00:f0:8a:3a brd ff:ff:ff:ff:ff:ff
    inet6 fe80::5054:ff:fef0:8a3a/64 scope link

Setup

Installed docker and libvirt on the Host

virbr0 network is internal kvm network virbr1 network created using terraform for guest only communication

                                                        vnet8

Question: how can I create a network config using terraform that uses direct host access (without creating a bridge on the host)?

hi! checkout

https://github.com/dmacvicar/terraform-provider-libvirt/blob/master/website/docs/r/network.markdown

if you find something otherwise we need to provide an example or research a bit. let me know

Hi, thx for the link - I already found that page, but as I understand this requires the configuration of a bridge on the host system, then linking the bridge to the vm using the bridge name: "The bridge network attribute is mandatory in this case"

yes, an example would be great!

hi @MalloZup! any chance to get some docs for this? thx and br

[scabala]

Hi @muj85 some upstream libvirt documentation: https://wiki.libvirt.org/VirtualNetworking.html What exactly do you mean by 'direct host access'?

[muj85]

Hi @scabala,

I solved it using bridge setup with script during kvm host boot process, later moved to systemd network config, works for me.

thank you!
