changing hostname for proxmox hypervisor

below steps can be used to get hostname changed for a existing running Proxmox server

Tried and tested on Proxmox version 3.4-6, Please use in dev environment first to gain more confidence.

nano /etc/hosts
nano /etc/hostname
nano /etc/postfix/main.cf
cd /etc/pve/nodes/
cp -r old new
rm -r old
cd /var/lib/rrdcached/db/pve2-node/
cp -r old new
rm -r old

Proxmox VE error "no accelerator found"

Proxmox is a opensource Hyper-visor solution.

It is meant for installation on physical servers but for practice, while trying to use it on a laptop/desktop having virtual box installed on it. Base Proxmox installation on virtualbox VM went error free.

While getting VM started created inside the proxmox created in virtuallbox an error observed i.e. "no accelerator found"

below ink has solution for the same.
