Improved graphical console for virtual guests

Summary

This feature aims to improve the user experiance for virtual guests' graphical console, by providing an accurate mouse pointer and higher screen resolution, without requiring manual configuration.

Owner

Current status

  • Targeted release: Fedora 11
  • Last updated: 2009-02-26
  • Percentage of completion: 50%

Detailed Description

In Fedora 10 and earlier the virtual guest console is limited to a screen resolution of 800x600. The PS2 mouse pointer operates in relative coordinate mode, meaning the guest pointer does not track the local client pointer 1-for-1. In Fedora 11 the goal is to have the screen default to at least 1024x768 resolution out of the box. New installs of F11 will also be provided with a USB tablet and X in the guest will automatically detect & configure this in absolute coordinate mode out of the box. This will result in a mouse pointer which tracks the local client pointer 1-for-1.

Benefit to Fedora

Increased screen real-estate of 1024x768 will improve usability of programs in the guest, in particular anaconda and firstboot which struggle to fit their whole UI into the current 800x600 real estate. Users of virt-manager and virt-viewer will have a mouse pointer which works without requiring a pointer grab

Scope

For the screen resolution change:

  • Enhance KVM/QEMU to identify its Cirrus card with the Red Hat PCI vendor ID
  • Enhance X cirrus driver to look for Red Hat PCI vendor ID, and thus enable 1024x768 resolution

For mouse pointer changes:

  • Add HAL FDI rules to identify the USB tablet and assign it a 'evdev' driver
  • Make virt-install/virt-manager enable a USB tablet for all F11 guest installs

How To Test

  1. Install a new guest using virt-install or virt-manager, being sure to select 'Linux + Fedora 11' as the OS type + variant
  2. Observe installer starting in 1024x768 screen resolution
  3. sing virt-viewer or virt-manager as a VNC client, the mouse pointer in the guest should track 1-to-1 with the local desktop mouse, and not require any pointer grab
  4. Complete install and boot new system.
  5. X should come up in 1024x768 resolution again, and mouse pointer should still be tracking 1-to-1 and not require pointer grab

For added bonus, look in /var/log/Xorg.0.log and verify that it enabled 'QEMU USB Tablet' device with evdev.

User Experience

The user will have larger screen real estate for the guest console, and a more pleasant mouse pointer

Dependencies

This impacts

Contingency Plan

If screen resolution changes can't be completed, guests will continue to use current 800x600 resolution

If mouse pointer changes can't be completed, guest will continue to use PS/2 mouse

Documentation

  • There should be no documentation required, since the core point of the feature is that everything should 'just work' without any configuration required by the user.

Release Notes

  • FIXME--Needed?
