New Proxmox VM with HassOS

This script will create a new Proxmox VM with the latest version of HassOS. To create a new VM in the local-lvm storage, run the following in a SSH session or the console from Proxmox interface

TMP=`mktemp -d`;pushd $TMP > /dev/null;wget -qO - https://raw.githubusercontent.com/whiskerz007/proxmox_hassos_install/master/install.sh | bash -s local-lvm;popd > /dev/null;rm -rf $TMP;unset TMP

After script completes, click on the new VM (the script will tell you the ID), click on the Hardware tab for the VM and change the Memory and Processors settings to what you desire. The Hard Disk can be expanded by clicking on it, then click on the Resize disk button above (Note: additional steps must be taken for storage to take effect in the VM after the first boot). The network MAC address can be changed by selecting Network Device and clicking Edit above. Once all changes have been made, click Start above.
