Description Justin Clift 2012-02-01 11:27:25 UTC
Description of problem:

  KVM can be instructed to save the audio output of a virtual machine, to a file:

    /usr/libexec/qemu-kvm -audio-help

  However, libvirt does not yet support this.

  It would be useful to add support for this to libvirt, so people can save audio output for layer playback or analysis.

Version-Release number of selected component (if applicable):

  Checked libvirt 0.9.9, and it doesn't appear to support this yet.

Comment 1 Daniel Berrangé 2012-02-01 11:33:26 UTC
IMHO libvirt is the wrong place to be doing this kind of thing. It should be done using SPICE or GTK, both of which have APIs (gtk-vnc & spice-gtk) which allow capturing of audio from the VM.

Comment 2 Justin Clift 2012-02-01 11:40:46 UTC
Yeah, adding it to client side apps would also provide much of the same result. :)

Comment 4 Cole Robinson 2016-03-23 20:45:51 UTC
As Dan said, libvirt isn't the right place for this
