[tor-relays] Installing Tor-ramdisk

Installing Tor-ramdisk I have question about installing Tor-ramdisk on Dedicated server in hetzner datacenter. I want install iso file without using USB and DVD . i followed this link[1] . My iso file is in my VPS that LARA could access to iso via SAMBA/CIFS . LARA shows me the iso file attached but after running KVM and press F11 the boot menu have my hard disks not "PepperC Virtual Disc 1 0.01" in boot menu . How i can mount Tor-ramdisk with KVM . i don't want pay € 21.01 for using USB stick/DVD .
