Using a virtual machine for Ardour/Jack on a pulseaudio host OS (Linux)
KVM works, VirtualBox doesn't in my tests.
Ardour and Jack do not play well with PulseAudio. On my Ubuntu 16.04 it kills Pulseaudio and that is a bit awkward. So I decided to install Ardour on a virtual machine, and I wanted to test the performance. So I installed Ubuntu Studio on VirtualBox and KVM too see which one gives me best performance for audio editing. In VirtualBox it seemed to work internally, but alas, no sound reached the host system, regardless of configuration Kvm/Qemu worked on the first try!
Host operating system is Ubuntu 16.04LTS
Guest operating system is Ubuntu studio 16.04
Virtual machine is KVM/QEMU
Using the virtual machine manager
You may want to share files between the host machine and the Ubuntu Studio VM. In that case: Mount a volume into the virtual machine like this:
Make a mount filesystem with driver Default in kvm, mode passthrough, enter "/commonshare" for target path.
Try in clientmachine
sudo mount -t 9p -o trans=virtio,version=9p2000.L /commonshare /mnt/commonshare
Then enter in /etc/fstab
/commonshare /mnt/commonshare 9p trans=virtio,version=9p2000.L,access=any 0 0
