How to get linux virtual machines working in Windows 7
I was having some problems getting linux virtual machines to run in Windows 7 virtual pc, here's some tips to get up and running.
Add i8042.noloop and vga=791 on your grub's kernel line to deal with mouse and video problems. The vga=791 overcomes virtual pc's 16-bit depth limitation.
I still can't get the linux vm to release the mouse, try some of windows existing keyboard shortcuts and see if they will do it. Ctrl+Esc worked on Ubuntu and Ctrl+Alt+Left Arrow worked on CentOS. Not ideal, but it works.
