boot machine using qemu

Question

I am trying to boot vm using qemu, the command that I use is

qemu-system-x86_64 -kernel /boot/vmlinuz-2.6.32-21-generic -hda /music/1gbfile

and its giving a error : Please append a correct "root=" boot option.

What does root mean here?

Try this:

qemu-system-x86_64 -kernel /boot/vmlinuz-2.6.32-21-generic -hda /music/1gbfile -append "root=/dev/hda"

You are basically making /dev/hda (which you provide with -hda argument) as your system's root directory. You can find more information here
