[U-co] Problema vmbuilder

[Hollman Enciso R.]

Hola *

estoy tratando de crear una maquina virtual con vmbuilder, he intentado de
varias formas encontradas en el google pero siempre me saca un error,
buscando en el LP veo que esta como un bug confirmado pero sin resolver,
aplique una solución dada en los comentarios pero a mi no me funcionó :(
"osea no es una solución" alguien sabe a que se debe este error, que podria
hacer ??

como nota lo he intentado hacer desde ubuntu 10.04, 11.10 y 12.04

Si alguien me da una luz se lo agradezco ;)

les dejo el comando completo con el proceso

root en nexus:/home/hollman# vmbuilder kvm ubuntu --suite=lucid

--mirror=http://de.archive.ubuntu.com/ubuntu-o
--libvirt=qemu:///system --part=vmbuilder.partition --user=hollman
