Dual NICs

cct · 03-10-2024, 09:23 AM

I have Ubuntu 22.04LTS on a Intel NUC12, running a few VMS under KVM/QEMU

I have set up a bridged NIC onto a USB NIC, and want to restrict that to the VMs, with the server only using the main NIC

Any thoughts?

Thanks, but that is the other side.

The VMs all route correctly using the bridged network, through the USB NIC.

What I am trying to stop is the host using the bridged network, just using it's own NIC

The simple way, using route to control this.

How will that stop the host responding to requests on that NIC?

All route entry on host points to the NIC you want, including default route entry.
