I met the similar problem. But I reset the only one virtual CPU core. that VM returned to normal. Then I tried to install Windows XP into an old vdi file with 2 CPUs on VirtualBox-3.1. After installation and rebooting the VM, the screen of VM turns to blue when loading into Windows. I know that developers just fix bugs of code of Guest SMP and there is no major change in Guest SMP. Maybe I should wait a maintenance update

Display card with hardware acceleration on the host and video acceleration coming from the driver of display card on the host. I have a ATi HD3650, running Fedora 12 with open source driver. I can not enable 2D Video Acceleration this feature. > > Regards > Rehan > -- My Page: http://www.liangsuilong.info Fedora Project Contributor -- Packager && Ambassador https://fedoraproject.org/wiki/User:Liangsuilong
