  • Two of the same MAC address can’t exist in the same IP space, else the router can’t route packets to them.

    Yes, this seems to be my problem, both the host and the vm got the same IP, and I think I cannot send any traffic to either my host or vm. So my router is probably confused, as you suggested.

    Is there an issue with using Docker for this?

    I forgot to mention this, docker indeed work. However, ha requires a privileged docker running as root, which means ha essentially runs as root on the host.

    This is fine on dedicated hardware, but as my server have other infrastructure on there, running ha as root can be a security risk.


  • Hi, thank you for your reply.

    Did you make sure that eno2 is enslaved by br0? When br0 is created, it indeed have a unique MAC, but once it enslaves the hardware, it inherits the hardware address.

    I have not tried to get the bridge going with virsh, but I was unsuccessful with the virt-manager ui. And I assume they use the same system?

    It is possible I have accidentally disabled some network virtualization kernel component during setup, as I have implemented some mods from secureblue. I will try to reset everything to default, and try again.

    Do you have a tutorial for making bridge via virsh that you can share.
