I want to use Sage 5.1 under VMWare Player 4.0.1 build-528992 . I successfully imported the virtual machine (sage-5.1.ova) by simply clicking open and ignoring any warnings (none of them seemed critical to me). However, when I now start the actual sage-5.1.vmx VM in the VMWare Player, it crashes (!) while booting the VM.
The last thing I can see is an error message after the login prompt:
sagevm login: [ 5.655611] vboxguest: VirtualBox Guest PCI device not found.
I know that VirtualBox is recommended, but I do not have admin rights on my PC and have to cope with VMWare Player (which is installed).
