Can't run librespot-java in a VM

[iVolt1]

I will first say that librespot-java works flawlessly for spotify audio and metadata and I appreciate the effort put into the project.

I previously reported this issue at spocon/spocon#46 .

I am running spocon in a virtualbox VM. Initially it took me a day or two to figure out why spotify could not see librespot-java.

It looks like this code excludes running VMs, possibly for no apparent reason. I changed the x08 to x06the MAC in the VM settings and now spotify connects to spocon.

Can this code be removed or modified so that librespot-java works out of the box in a VM? At the very least could a warning/workaround be put into the readme install instructions?

Hello,

Are you still able to capture metadata, etc as of yesterday?

[iVolt1]

I haven't updated or changed anything in quite a while, but librespot-java is working and sending metadata.

I use this project that is built on librespot-java and it appears to have went down. https://github.com/entriphy/sp-playcount-librespot I wasn’t sure if it’s the librespot project that broke it. I tried deploying my own instance and something also is working. I’m trying to figure out where the issue lies 😔

Hi devgianlu,

This issue still exists even in the latest releases of librespot-java. I have gotten stuck in a troubleshooting loop a few times when after many months I have had to move my librespot-java/owntone environment to a different vm and the librespot-java server device doesn't appear in spotify. I eventually remember that the code excludes those mac addresses and have to go into the vm settings and fake the mac address.

Is there a reason to exclude librespot-java from running in a vm such as a spotify licensing issue? librespot-java runs runs great for me in hyper-v and VirtualBox so it would be nice if that code could be removed in the future.

I currently run the librespot-java/owntone environment in the HomePod Connect addon on Home Assistant and works Home Assistant dashboard which is probably the best whole house audio arrangement anywhere, even in a vm.

It looks like this code excludes running VMs, possibly for no apparent reason. I changed the x08 to x06the MAC in the VM settings and now spotify connects to spocon.

Thanks for the great project,

@jpgrovy I think you posted in the wrong thread, but your project looks promising.

I think this issue reported by @dolanjp was also a vm exclusion issue:
