I use a synology 918+ NAS at home. Because of SMB version problem, I switch the synolgoy roon core to windows core. After using a while, I felt I have to 24hr running the windows core to keep the roon ruuning. For my home network, I use the policy routing to route the Internet traffic. so that, it is not convenient running windows core with two NICs on my PCs. I have to switch enable and disable the one of NIC or changing route manually in order to keep the PC can have the proper routes pre-defined on the router.
I have to switch back to synology or buying a new NUC using ROCK. At least $600-800 Intel 8th generation NUC. still feel little expensive. I started looking for VM solution, because the synology spk core have the Airplay and SONOS problem, also the SMB bugs (It can be solved install the SMB 1.0 version at server end. But synology FILE STATION completely no problem to mount any version of SMB, so I think manually install the SMB 1.0 to use the network folder is stupid way). According to the community topics, someone said the problem caused by the open vswitch default enabled in synology. I run tests. The synolgoy AUDIO STATION discover the Airplay 1 &2 without any problem . So I confirm that just another excuse for SPK ROON. I also saw the topic whom want running ROCK under ESXi. There is no people explain every step very clearly. Also, no one want share the OVA in public.
The biggest problem is keyboard interactive in VM host. I found the VMWARE workstation 14 solution is not using vmx file modification with usb.generic.allowhid = true. Actually I tried, but VMWARE displayed error to cancel the vm host starting. finally, It only need click setting in the the VM host according to the VMWARE GUIDE.
You can use any VM. NO AIRPLAY and NO SONOS problem at all in synology VMM. And you can add second virtual disk for your self if you need internal storage. The second drive have to be IDE in order the ROCK can recognized.
My OVA default setting are 1 CPU 4 core 4GB memory 256GB virtual HDD, 2*network cards to cross VLANs. It’s the 193MB OVA file. It already updated to ROON 1.6 version. According to danny’s reply below, I remove the OVA SHARE LINK. But I will answer the question anyone ask. I just want any paid ROON user can use it without any basic function not working.
