[RDD] Rivendell Virtual Machine
Hi list. I'm new to rivendell, but I have some years of experience in cloud computing and virtualization. I'm using rivendell VMs (although everything just mockup/tests for learning) very successfully (to the moment) toghether wit physical rivendell PC, in a mixed physical / virtual mockup (I use PROXMOX for virtualization)... To 'move'/'share' audio between hosts my advice is to check JackTrip: https://github.com/jacktrip/jacktrip It is meant (although not mandatory) to do exactly that, far, far easier than NetJack stuff It is a 'normal' jackd server client application that allows to move audio very very easily between other jackd hosts, both over LAN, but also over WAN (with its logical limitations). If you prefer GUI, check a branch on the repository called qjacktrip (still in development, but very much useable to my taste) which provides a nice GUI Qt application to handle jacktrip from the desktop. As of Debian (I'm debianist) Buster, jacktrip packaged release is quite old and not much functional to my taste ( Bullseye/testing includes quite a recent 1.3.0 version)... So I have created a .deb package that provide both latest jacktrip and qjacktrip for debian 10 Buster if someone's interested. Best regards. ___ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
Re: [RDD] Rivendell Virtual Machine
Thanks Eric
Seems you too are sending audio out from the Guest to a different sound
setup..am I right.
I had a look at pass-through for Pulse but it got down to scripting
which I'm not quite there yet with.
I am not using USB at this point because the Audigy is listed as having
compatibility for Rivendell on Centos at least.
thanks

just not possible. I was contemplating passing through a USB PCIe
card and plugging a device in there but since we're feeding across
rooms we opted to stream to a hardware stream decoder from our VM for
now. We may revisit this in our set up. It's been running on air
just over a year now.

Thanks Steve,
I see what you mean.. alas I'm using the host soundcard and not
sending the audio to another server which would of course be a
production setup. I might try the VMWare route but its just a lab
for now, and I wanted to get as bare metal as I could. I suppose
what I need to do is somehow get audio pass-through working in
Libvirt.. still learning...Might have a go with ESxi. Thanks again.

I have many Rivendell setups in VMWARE and it works great.
However, I am using the Livewire driver and Axia xNodes or other
Axia devices as the sound cards. I did try using a USB sound
card once, and didn’t have much success with this setup.

Hi all,
I have been playing with a Rivendell Virtual Machine.
It's Rivendell 3.5 on Centos 7 using a Libvirt KVM Guest and a
Soundblaster Audigy card.
An NFS share on the KVM host for audio files (not yet imported)
and a reasonable Virtual HDD storage space for them once
converted from FLAC to Wav.
All is well except, the sound quality. On first listening the HDA
(ICH9) works OK but has slight distortion, which is much more
noticeable when using the test tone supplied from the build.
I know this is not a production build ( I'm still learning hence
the VM) but I wondered if anybody else has had success with this
kind of setup.
I would be interested to hear.
cheers,
Chris Perkins

Re: [RDD] Rivendell Virtual Machine
Hi David Thanks for the info..grateful for any info or pointers. I am not aware of CAED, is there a description or tut anywhere. My aim in using Libvirt KVM is to be as bare-bones-bare-metal as possible to lower costs. I support a very small local station strapped for cash and staff. Also I would be interested in net-jack if only I could get my head around plain ol' JACK but that's for the next phase I guess.

I support a couple of Rivendell installations that use Libvirt KVM guests. I recognize me descriptions below do not implement the use-case you describe, but I thought I would toss it out anyway. If you are willing to run the Rivendell service on the bare metal host, you can use Rivendell itself (via caed) to route the audio from the guest(s) to the host. That way you do not need to expose any audio cards to the guest(s). This has the additional benefit that if you run multiple guests, they can all use any of the host's configured audio devices. Another way to achieve the above is to use netjack. This might be a smaller, lighter-weight solution than a full-blown Rivendell installation on the bare metal. Let me know if you want more details on either of these possible solutions. And please do report back what you end up doing!

Re: [RDD] Rivendell Virtual Machine
I'd be interested in hearing about net jack, looked into it a while back, but couldn't wrap my head around the set up at the time.
