What is OpenWRT?
--------------------------------------------------------------------
OpenWrt is an open-source project for embedded operating systems based on Linux, primarily used on embedded devices to route network traffic. The main components are Linux, util-linux, musl, and BusyBox. All components have been optimized to be small enough to fit into the limited storage and memory available in home routers. - https://en.wikipedia.org/wiki/OpenWrt

Creating the VM
--------------------------------------------------------------------
   01. Open a web browser and navigate to the ProxMox web UI https://ProxMoxDNSorIP:8006/
   02. Click the Create VM button at the top right
   03. On the General tab, name the VM OpenWRT and set a VM ID (123 in this example) ≫ click Next
   04. On the OS tab select Do not use any media and set the Guest OS Type to Linux and Version to 5.x - 2.6 Kernel ≫ click Next
   05. On the System tab click Next
   06. On the Hard Disk tab set the Disk size to 0.001 ≫ click Next
   07. On the CPU tab set the number of CPU cores and the Type to host ≫ click Next
   08. On the Memory tab set the amount of memory to 256 MiB ≫ click Next
   09. On the Network tab set the Model field to VirtIO (paravirtualized), Uncheck the Firewall box ≫ click Next
   10. On the Confirm tab review the settings and click Finish
   11. Select the newly created OpenWRT VM from the left navigation panel
   12. Select Hardware from the left sub-navigation menu
   13. Click the Hard Disk to select it
   14. Click the Detach button at the top of the main content window to detach the hard disk from the VM
   15. Click the Unused disk to select it
   16. Click the Remove button at the top of the main content window to permanently delete it
   17. Click the Add button ≫ Network Device
   18. Set the Model field to VirtIO (paravirtualized), Uncheck the Firewall box ≫ Click Add

Setting Up the OpenWRT Disk
--------------------------------------------------------------------
   01. Select the Proxmox node name in the left navigation menu
   02. Click Shell in the left sub-navigation
   03. Run the following commands in the terminal
         lookup the latest stable version number
         regex='≪strong≫Current Stable Release - OpenWrt ([^/]*)≪\/strong≫' && response=$(curl -s https://openwrt.org) && [[ $response =~ $regex ]] && stableVersion="${BASH_REMATCH[1]}"
         download openwrt image
         wget -O openwrt.img.gz https://downloads.openwrt.org/release...
         extract the openwrt img
         gunzip ./openwrt.img.gz
         rename the extracted img
         mv ./openwrt*.img ./openwrt.raw
         increase the raw disk to 512 MB
         qemu-img resize -f raw ./openwrt.raw 512M
         import the disk to the openwrt vm
         update the vm id and storage device as needed
         usage: qm importdisk
         qm importdisk 123 openwrt.raw HDD_500GB     
   04. Once the disk import completes, select the OpenWRT VM from the left navigation menu ≫ Hardware
   05. Double click the Unused Disk ≫ Click the Add button
   06. Select Options from the left sub-navigation menu
   07. Double click Boot Order
   08. Check the Enabled box next to the hard disk
   09. Drag the Hard disk up in the boot order as needed, typically below the CD-ROM device
   10. Click OK
   11. Double click Use tablet pointer ≫ Uncheck the Enabled box ≫ Click OK
   12. Click the Start button in the top right of the screen
   13. Click the Console link to watch the boot process
   14. Wait for the text to stop scrolling and press Enter
   15. Run the following command to change/set the root password
         passwd     
   16. Type a new root password twice to set it
   17. Continue the configuration by running the following commands
         set the lan ip address, use something in the same subnet as your LAN
         uci set network.lan.ipaddr='10.10.27.151'
         restart network services
         service network restart
         update openwrt packages
         opkg update
         install the luci web ui
         opkg install luci     
   18. Open a new browser tab and navigate to http://IPofVM, http://10.10.27.151 in the example
   19. At the login screen, enter the username root and the password set above ≫ Click the Login button
   20. Enjoy OpenWRT running in Proxmox
