How do you setup KVM networking on a desktop or laptop
-
@matteo-nunziati more accurate: VM can re-enter the host, the host can't re-enter in VMs. just double-checked.
-
I kind of have a mix. Most are macvtap over a bond and I just set up a private network between the host and VMs. I set reservations with libvirt for the VMs.
I have a couple with full bridge, but since I'm managing the systems from outside of the host, it really doesn't affect my workflow. The only thing that really changes is I use the private network for grabbing updates from my repo server. But if you are downloading updates and installing from the internet, this will make no difference to you.

@Romo That is what I was thinking also.
By default this is the list of options.
So I assume, I need to make a bridge first as I did not see any other settings.
Yes, you have create your bridge first so that it appears in virt-manager.
Virt-manager can create a bridge for you, but you have to disable NetworkManager and use network instead. IIRC Birthday-manager has some issues with NetworkManager.

Any further updates here?
What is the "cleanest" method available so vm's can "talk" to the host?

Bridge. But sometimes is messy with the wifi in my experience, so maybe is better to use ZeroTier for a testing environment.

I usually use the Linux Bridge since it provides the features I require and they are relatively simple to set up.
macvtap should provide better performance cause it is the evolution of Linux bridge, and I use Fedora Virt-Manager to setup this and connect to KVM
@Francesco-Provino Why would macvtap have better performance vs bridge?

I ended up just staying on macvtap. I never did any further troubleshooting.
I only use this Windows 10 VM for occasional power email sessions in Outlook when organizing 5 accounts worth of email. Usually once a week.

You'll get better performance if you install the VirtIO drivers and use that instead of rtl8139. Whether you will notice it or not for that VM, idk.
