Qemu Video Performance

To optimize video performance under Qemu you should use a 16-bit colour depth on both the host and guest operating systems. To set 16-bit colour depth do:

$ sudo gedit /etc/X11/xorg.conf

Find the line which starts 'DefaultDepth' and change it so that it reads...

!DefaultDepth    16

Remeber to restart X in order to make your changes take effect.

Qemu Launcher

Qemu Launcher is a GNOME / Gtk front-end for Qemu which can Create and save multiple VM configurations and can create disk images from the GUI using dd, qemu-mkcow, and vmdk2raw for raw, COW, and VMWare converted images respectively.

Problems

A couple of errors that might crop up:

Could not open '/dev/kqemu' - QEMU acceleration layer not activated

This one was because the kqemu module had not been loaded, or because the device was not present. See the /QemuCompilation page about kqemu.
