Make sure that the interface that you are bridging to is not a wireless interface otherwise it won't work. Very deep in the documentation about setting up KVM there is a warning about that it's something about how they initiate connections on a wireless interface is different than on a wired one and it breaks things in KVM bridging.

Hi,

I've got a dedicated server with OVH and I'd like to host a public VM. I'd like Centos OS 7 or 8, I installed KVM already, I got the VM and bought the IP and created a virtual mac id. I know I have to bridge it somehow but I can't seem to find a proper tutorial. Do you know where to start?

You can do next: 1) Create bridge interface (for example br0) on dedicated server. Associate this interface with your Ethernet interface and assign IP address to br0. 2a) When you would create VM add parameter --network=bridge:br0 to the virt-install in command line. Or smth similar if you create VM in another way. 2b) Or edit xml file for your VM and add or change config: <interface type='bridge'> <mac address='insert_you_virtual_mac_here'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </interface> 3) Inside the VM assign real/public IP to you Ethernet (probably eth0) interface.

That's all.

If you have additional questions or you need more detail explanation you can write me directly.

You can create bridge in CentOS 7 withbr command line tool. In case if CentOS 8, bridge can be created with nmcli, cockpit or nm-connection-editor.?
