The logical next step will be to try it with some sort of AoIP (NetJACK or LiveWire). I have no idea if KVM supports a full class 2 multicast implementation (needed for LiveWire), so it’ll be an interesting experiment. MySQL? Storage, With what method? Both on a external, dedicated server (not virtualized). A straight BroadcastAppliance 2 setup (CentOS 6), with audio stores shared via NFS. Cheers! |--| | Frederick F.

Re: [RDD] Running in a virtualised environment
Hi all, Here at Radio Capelle we're running in a virtualises environment since we started using Rivendell (early 2014). If you like, I can pass this thread on to our IT-manager (who got it all figured out). Cheers, Peter Verstuurd Van: Lee Baker Verzonden: maandag 27 april 2015 13:08 Aan: Lorne Tyndale CC: User_discussion_about_the_Rivendell_Radio_Automation_System Hi Lorne, Glad you mentioned that, I had a secondary system which mirrored the main system so in the event of a failure I was able to bring everything back online quite quickly. The other great thing of running in a virtual environment, you can have your ³golden image² ready to go in the event something screws up with the RD system. The amount of times I¹d make a change to and broke the system and have to rebuild it was rather frustrating and time consuming. By virtualising I not only reduced an entire rack of servers in to one server and a backup server thus also reducing environment costs such as power consumption I reduced down time and maintenance. My other requirement was to have the backup service off site in the event of internet dropouts or power outages, in the previous setup of multiple physical servers it was just too complicated. This was being used for internet based radio stations delivered to paying customers in a retail environment. That is basically what put me on the path to testing running a physical studio off a virtual system. Of course redundancy is the key, being able to quickly migrate the main service over to your backup service with very little down time. I had the virtual server running non stop for 6 months without issue, only reason I had to reboot was because of a power outage that lasted longer than the UPS could hold the system up for.

[RDD] Running in a virtualised environment
Hi All, just thought I¹d throw something in. I have been doing a little playing around of late as I recently purchased some thin clients. For a while now I have been running RD in a Vmware environment successfully running up to 10 stations on one system. Now I have recently discovered that ENCO have a virtualised setup and utilise thin clients for accessing the playout, all audio is routed via IP. Being that RD can utilise Axias IP software sound card for stations who use Axia could also run RD under Vmware. Now normally you would connect to these virtual Pcs using VNC, however I¹ve found x2go client/server to work quite nicely. By running x2go server on the RD system I connect to the to it from a thin client running the x2go client and published apps. You can then natively bring Rdairplay through and it¹s like you¹re operating from a physical system. It all works quite nicely. ___ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
