Need help running homeassistantOS as a VM. VM doesnt receive ipv4 address. (discuss.tchncs.de)

I have a local network where all the devices receive their ip from the router. IP range is 192.168.0.XXX.

On one of those machines i want to run "home assistant operating system" inside a VM using libvirt(using cockpit webgui).

I was able to install the VM, but when I run it, it never receives a IP address. Setting one manual works, but then the VM doesn't show up in my local network.

On the host machine I created a bridge (virbr0) and I made the nic(enp8s0) from the host member. I also made VM member of virbr0

Any ideas what i'm doing wrong?

Note that the VM also needs to become member of the local network (ip range 192.168.0.XXX) and needs to see all other members of the local network.

Could it be that you need to run the VM network in NAT mode, instead of a "Bridge" mode?

Please note, I have little experience in troubleshooting these, I'm just spitballing ideas here...

No, then the VMs would get their own subnet. You want the NIC bridged so that the router actually sees the VMs.

Gotcha. I learned something new. Thanks :)

output from "nmcli device status" command:

DEVICE TYPE STATE CONNECTION
virbr0 bridge connected virbr0

so i assume its in bridge mode?
