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.

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. ------------------------------ Message: 2 Date: Sun, 13 Sep 2020 13:15:02 +0000 (UTC) From: Soumya Bhowmik <som3939 at yahoo.co.in> To: Discussion about the virtualization on CentOS <centos-virt at centos.org> Subject: Re: [CentOS-virt] Centos + VM + public ip Message-ID: <868650482.1233750.1600002902917 at mail.yahoo.com> Content-Type: text/plain; charset="utf-8" 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.?
