QEMU PC emulator version 0.9.1 (kvm-83-maint-snapshot-20090205), Copyright (c) 2003-2008 Fabrice Bellard
usage: qemu [options] [disk_image]
'disk_image' is a raw hard image image for IDE hard disk 0
Standard options:
-M machine      select emulated machine (-M ? for list)
-cpu cpu        select CPU (-cpu ? for list)
-fda/-fdb file  use 'file' as floppy disk 0/1 image
-hda/-hdb file  use 'file' as IDE hard disk 0/1 image
...
-clock          force the use of the given methods for timer alarm.
                To see what timers are available use -clock ?
-startdate      select initial date of the clock
-icount [N|auto]
                Enable virtual instruction counter with 2^N clock ticks per instruction
During emulation, the following keys are useful:
ctrl-alt-f      toggle full screen
ctrl-alt-n      switch to virtual console 'n'
ctrl-alt        toggle mouse and keyboard grab
When using -nographic, press 'ctrl-a h' to get some help.
