Hi,
I want to use a ram disk as a block device for my kernel.( i am
measuring file io on ram )
I am trying to boot a kernel from using /dev/ram0. However I am getting
"No root Device found"
qemu-system-x86_64 -m 8G -hda disk.img -kernel vmlinuz-3.10.0-rc6

but to a level probably decided by the system.
I am not able to explain this part who d
