CentOS virt - Sep 2020 - Centos + VM + public ip

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?


Thanks

Don't  you need to talk to OVH about this? I know how I'd do it in my
own network setups, or AWS, or Google, but I'm sure these folks have
their own tools.

It's not an OS problem, it's a classic IT problem. Just the sort of
thing that DevOps would set up standards and basic practices for.

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.?
