[opensuse-factory] Fail to install 11.4 M6 on Virtualbox PUEL

Hello, I tried to upgrade my 11.4 guest running zypper dup, then zypper downloaded/installed more than 1000 pkgs, at reboot X stops to starts. Then I downloaded 11.4 Build 1034-i586 and attempted to install it as guest on Virtualbox 3.2.12, in this case it has been a worst case since installation crashes after drivers loading. Wonder if are there some workaround in order to install M6 on Virtualbox PUEL.
