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

submitted 10 months ago by [email protected] to c/selfhosted

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.

OP, are all of the working-as-expected VMs also members of the virbr0 network?

I'm thinking that this is a firewall issue on your VM host. If you DO NOT have any other working VMs then could you try disabling the firewall on the VM host and see if the VM can receive DHCP traffic.

I currently have no other VM's running. I'll see if disabling the firewall helps.

Did you ever figure out what was causing your issues?

No sadly I didn't. I got it working a few times after reconfiguring everything but it never survived a reboot.
