I'm agnostic about lkvm, but the following command does all the above: qemu-system-x86_64 -enable-kvm -net nic,vlan=0,model=virtio -net user -fsdev local,security_model=passthrough,id=root,path=/ -device virtio-9p-pci,id=root,fsdev=root,mount_tag=/dev/root -m 512 -smp 2 -kernel /usr/src/linux/arch/x86/boot/bzImage -nographic -append "init=/bin/zsh root=/dev/root console=ttyS0 kgdboc=ttyS0 rootflags=rw,trans=virtio rootfstype=9p ip=dhcp" If you want your host root-fs to be mounted rw (to copy data back and forth) you need to run to above as root and add "rw" to the kernel options. -- Markus -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
