I have a windows 2008 r2 64bit server guest which goes to 100% cpu load right after vm started. Host OS ist ubuntu 10.04 LTS 64bit VirtualBox is current version. Guest additions are current. Problem was allready occuring with 4.1 version of VirtualBox. As a noob i have no idea how to debug this. Sometimes the vm is running after boot and freezes some hours later, but then vm hangs right after booting after multiple times. Starting the vm in save mode is fine, but unusable of course. :( What to do?",defect,closed,other,VirtualBox 4.2.6,fixed,,,Windows,Linux
