I would have thought that correct emulation would allow those same low-level calls in a VM. AFAIK the guest system can read the whole CD as a raw device (assuming appropriate privileges). > As I said, I don't know if this explanation is correct, but I do know > that some of my games will not load when running in a VM, so I have to > have a native Windows boot. One reason for some games not working is that they require a better graphics card than the one emulated by the VM. poc -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
