Create an image which emulates the Hard Drive.

kvm-img create -f qcow2 debian8.img 20G

Boot the virtual machine

kvm -m 512 -cdrom  debian-8.1.0-amd64-CD-1.iso -drive file=debian8.img,if=virtio,index=0 -boot d -net nic -net user -nographic -vnc :1

Connect to the Virtual Machine through VNC (use display number :1).For Example, where is the IP address of the host machine

vncviewer :1

Select “Standard system utilities” during installation. Once the installation is complete, shutdown the Virtual Machine. Now start the Virtual Machine to boot from the Hard Drive using the following command

kvm -m 512 -drive file=debian.img,if=virtio,index=0,boot=on -boot c -net nic -net user -nographic -vnc :1
