If your Synology is running DSM6, you should do a full HAOS install using the VMware image using Synology’s VMM package. The only gotcha is that the USB port will disconnect from the VM whenever you reboot the NAS, so you will need to manually re-attach it before your Zigbee dongle will be accessible again…
Good idea.
I have checked what it takes to run VMs on the old DS412+. Unfortunately, it seems that the hypervisor (Virtual Center from Synology) cannot be run on the old thing.
Is there a third party hypervisor for this or a container that runs the VM?
