I'm trying to do kernel module development and am looking for how to load the exact same kernel that my host OS is running.

kvm -net nic,macaddr=52:54:00:12:34:56 -net tap,ifname=qtap0,script=no,downscript=no -kernel /boot/kernel-2.6.32-gentoo-r7 -hda /dev/sda -boot c -m 512


If I load the above command, the guest OS loads the correct kernel, but also mounts everything on my hd as rw, which isn't what I want. I want everything on my hd to be protected.

If I load the following command, it works, but it's a very bloated livecd kernel, and not the version I'm trying to develop to.

kvm -net nic,macaddr=52:54:00:12:34:56 -net tap,ifname=qtap0,script=no,downscript=no -hda ./gentoo-i386.img -cdrom ./livecd-amd64-installer-2008.0.iso -boot d -m 512


Can anyone help out w/ how I should run the kernel off my current host OS, yet protect the rest of my system?
