BoF: PV Audio on Xen, Stefano Panella, Citrix

Sign up or log in to save this to your schedule and see who's attending!

Developing a good PV audio solution for Xen is not as simple as it seems. On Xen the audio data bandwidth is not a problem, but the synchronization and the Real Time nature of a real audio card is difficult to workaround. Stefano Panella would like to share some lessons learned developing a PV Audio solution compatible with linux and windows guests, showing the differences in the required guest API (alsa driver for linux, WaveCyclic and WaveRT drivers for Windows). Using a PV audio solution it would be possible to have Acoustic Echo Cancellation working, difficult to achieve with a pure audio emulation. Stefano would also like to discuss about what would be needed to upstream a PV Audio solution, which would involve changes in Xen, qemu and linux.


Stefano Panella

Stefano Panella comes from an embedded programming background and has previously worked on wireless technologies and graphic remoting. He is currently working for Citrix in the XenClient team and he is leading the development in the audio subsystem on Xen. Stefano has also done some work in the linux qemu stubdomain area to improve security in XenClient and that work has highlighted the need for a general PV audio solution.
