Gracias a esa página ya tengo todo funcionando, es que Ubuntu es un poco rarito 
Por cierto, ¿como hago para instalar alguna cosa en windows? El lector de CDs me aparece vacío.

Muchas gracias, lo he conseguido con la consola.
Salu2 

Hola, tengo instalado el vmware en suse 9.3 y me va muy bien pero como no es gratis decidi probar el quemu y siguiendo  este manual que esta muy bien explicado llegue al ./configure y todo bien, el problema esta en la compilacion ya que me da un monton de errores   /QUEMU/qemu-0.7.2> make && su -c make install

Si alguien sabe cual es la razon le agradeceria una respuesta ya que me gustaria bastante usar quemu y quitar vmware.

Ya habia oido hablar de BOCHS pero he leido que quemu va mas rapido, bueno por probar no pasa nada.

Aunque me gustaria quitarme la espina de no haber podido instalar quemu.

Un saludo

Hola, ya he resuelto el problrema, el fallo era que no tenia instalado el paquete zlib.

En caso de querer desistalarlo como se haria porque no veo ningun  archivo uninstall y la la verdad es queria probarlo y luego quitarlo.

Un saludo.

Agregado la parte de instalar mediente apt desde debian con código fuente ( colaboración de NeoCalderon )..

Revisaré esto, al parecer ya hay soporte para usb y la emulación mediante tun/tap creo xD para agregar la maquina virtual a nuestra red..
