address@hidden:~/temp$ qemu-system-x86_64 -m 256 -display curses -drive
file=disk.cow -drive file=boot.img
WARNING: Image format was not specified for 'boot.img' and probing guessed
raw.
Automatically detecting the format is dangerous for raw images,
write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
This is OK, as I don't want anything writing to that thing anyway. So to
get rid of the waring:
address@hidden:~/temp$ qemu-system-x86_64 -drive
file=boot.img,format=raw,readonly qemu-system-x86_64: Can't use a read-only
drive
qemu-system-x86_64: Initialization of device ide-hd failed: Device
initialization failed.
hmm... one more try:
address@hidden:~/temp$ qemu-system-x86_64 -m 256 -display curses -drive
file=disk.cow,readonly
qemu-system-x86_64: Can't use a read-only drive
qemu-system-x86_64: Initialization of device ide-hd failed: Device
initialization failed.
