Slow console performance in Ubuntu

The console on Ubuntu 10.04 server is painfully slow under virtual machine. The solution is to disable the frame buffer. Just append "blacklist vga16fb" to the end of the /etc/modprobe.d/blacklist-framebuffer.conf, save and reboot. (To prevent gdm from loading replace "quiet splash" to "text" in the /etc/default/grub and run update-grub.)
