Video mode problem under VirtualBox After installation, under VB 2.1.8, I encountered the same problem that has been under QEMU:
http://groups.google.com/group/comp.os.plan9/browse_thread/thread/bb7e753ab87ef983/d5e35c3374f58902 And solution the exact same, rebuild kernel: 1.) user none % 9fat: % ramfs % ed /n/9fat/plan9.ini replace strigs monitor=vesa => monitor=ask vgasize=1024x768x24 => vgasize=ask 2.) reboot under glenda and rebuild kernel % cd /sys/src/9/pc % mk 'CONF=pcf' % 9fat: % cp /sys/src/9/pc/9pcf /n/9fat/ 3.) reboot, set '1024x768x24' and 'vesa' 4.) video works OK Maybe someone who has English better than I have add this solution to "Installation troubleshooting (Plan 9 wiki)"?
