SPICE Roadmap
The future of Open Remote Computing
Presentation for KVM Forum 2011
Alon Levy, Red Hat

2. Overview Demo What is Spice Architecture Why Spice
New stuff from last year
Short term plan
Long term plan
Possible to use openoffice on a vm to do the presentation.
Linux
Demo
Mouse seamless
Copy paste (text + printscreen)
Sound
Video (wildlife)
Explorer
Device manager

3. What is Spice?

4. What is Spice?
An Open Remote Computing / Virtual Desktop Interface protocol
Free LGPL implementation
Remote display through paravirtual graphics to the host server to the client
Additional channels for:
Sound & Inputs (keyboard and mice)
CAC Smartcard
USB Redirection
Future extenstions

5. Advantages

6. Advantages
Use para-virtual device => natural API, not screen scraping
Minimize guest exits
Client side rendering
Multiple sockets
Occlusions Display Tree
Audio and Video

7. Advantages (cont) Copy-paste Sound USB Smartcard
From boot (VGA emulation)
Open Source

8. Changes from 2010 WAN support (wip) Copy paste
First class Linux support
GTK Widget
Virt-manager and virt-viewer
X driver improvements
agent
Smartcard channel
Wan: Added lossy compression with fallback taking into accound dependencies
C&P: Text and images
Wan support:
bandwidth detection
Jpeg (tricky)
More compression
Guest feature reduction
X driver improvements
Reaching for XRANDR next

9. Roadmap http://www.spice-space.org/page/PlannedFeatures

10. Short term USB channel Replace current proprietary solution
Isochronous + 2.0
Multiple concurrent client support

11. Mid Term Rootless windows / Desktop Integration
Testing infrastructure – autotest
Performance
No rate limiting
Better compression
Surfaces introduced, but not used correctly
Mac client (GTK)

12. Long Term Agent consolidation More clients (android, iOS)
3D Support (BoF)
Video acceleration
Guest OS level API's
Gallium helps?
Gstreamer
Agent consolidation – matahari / virt-agent?

13. Long Term - Discuss-able
Virtio rewrite?
Flash passthrough
Use glib?
Virtio rewrite
Support more architectures
Less driver work (but graphics is different)
Use glib
Remove NIH event loops, gain debugging, easy scriptability, gtk backend?

14. Questions?
Thanks for Listening!

15. Architecture Explain calmly and slowly. GDI was invented at ___
Rendering is client side.
Errors:
Driver above should be virtio-driver
Color of Guest OS should be different then color of Spice server?

16. QXL graphics workflow
Without a driver we fall back to VGA emulation (i.e. Everything works even without a driver, for example in the BIOS)
