How to install clearlinux on a running VPS

Hello, I want to try clearlinux on my vps.But my vps provider don’t provide clearinux images.So I have to install it by myself.

I try to boot iso image using grub, but every time I try, it end up showing someting like “unable to find boot media”.

This is what I have:
A kvm-based vps, a VNC console(in order to control vps while reboot),a ram-bootable linux iso(archboot from archlinux).

What should I do to install a clearlinux?

And this is the grub menu I tried to boot, but end up faild
menuentry “clearlinux” --class iso {
