--= Getting Started with Proxmox VE LXC and VM Templates =
++List and import lxc templates:
--Proxmox VE (PVE) allows users to create and manage both LXC containers and KVM virtual machines (VMs). This guide walks you through the process of downloading, importing, and creating templates for both.
--
--== LXC Templates ==
--
--LXC containers are lightweight and ideal for running Linux services with minimal overhead.
--
--=== List Available Templates ===
--
--To view the available LXC templates:
--
--{{code language="bash"}}
++```
  pveam list
--{{/code}}
--
--=== Download Templates ===
--
--Use the pveam download command to import templates to the local storage:
--
--{{code language="bash"}}
  pveam download local ubuntu-22.04-standard_22.04-1_amd64.tar.gz
  pveam download local ubuntu-24.04-standard_24.04-1_amd64.tar.zst
  pveam download local debian-12-standard_11.7-1_amd64.tar.zst
--{{/code}}
--Once downloaded, these templates can be used to create new LXC containers from the Proxmox web interface or via CLI.
++```
--== VM Template from Ubuntu Cloud Image ==
++Download ubuntu 24 and create a template:
--KVM VMs are ideal when you need full virtualization, for instance, to run Windows or more complex Linux systems.
--
--=== Download Ubuntu Cloud Image ===
--
--Download the official Ubuntu 24.04 cloud [[image:]]
--
--{{code language="bash"}}
--wget http://cloud-images.ubuntu.com/releases/24.04/release/ubuntu-24.04-server-cloudimg-amd64.img
--{{/code}}
--
--=== Create the Virtual Machine ===
--
--Create a new VM with ID 910 (you can pick any unused ID):
--
--{{code language="bash"}}
++```
++wget http:~/~/cloud-images.ubuntu.com/releases/24.04/release/ubuntu-24.04-server-cloudimg-amd64.img
  qm create 910 -name template-ubuntu-jammy -memory 2048 -net0 virtio,bridge=vmbr0 -cores 2 -sockets 1
--{{/code}}
--
--=== Import and Attach the Disk ===
--
--Choose the correct storage (replace nvme if you use a different storage name):
--
--{{code language="bash"}}
++qm importdisk 910 ubuntu-24.04-server-cloudimg-amd64.img nvm
  qm importdisk 910 ubuntu-24.04-server-cloudimg-amd64.img nvme
++qm set 910 -scsihw virtio-scsi-pci -virtio0 nvm:vm-910-disk-0
  qm set 910 -scsihw virtio-scsi-pci -virtio0 nvme:vm-910-disk-0
--{{/code}}
--
--=== Configure the VM ===
--
--{{code language="bash"}}
++qm set 910 -scsihw virtio-scsi-pci -virtio0 unused0:nvme:vm-910-disk-0
++qm set 910 -scsihw virtio-scsi-pci -virtio0 nvme:vm-910-disk-0
  qm set 910 -serial0 socket
  qm set 910 -boot c -bootdisk virtio0
  qm set 910 -agent 1
++qm set 910 -gotplug disk,network,usb
  qm set 910 -hotplug disk,network,usb
  qm set 910 -vcpus 1
++qm set 910 -vga qml
  qm set 910 -vga qxl
++qm set 910 -ide2 nvm:cloudinit
  qm set 910 -ide2 nvme:cloudinit
  qm resize 910 virtio0 +8G
--{{/code}}
--
--
--If your disk is using SCSI instead of virtio, resize like this:
--
--{{code language="bash"}}
++qm set 910 -scsihw virtio-scsi-pci -virtio0 nvme:vm-910-disk-0
++qm importdisk ~-~-hwlp
++qm importdisk ~-~-help
++qm resize 9001 virtio0 +8G
++qm resize 910 virtio0 +8G
  qm resize 910 scsi0 +8G
--{{/code}}
--
--=== Convert the VM into a Template ===
--
--{{code language="bash"}}
  qm template 910
--{{/code}}
--
--Now you can use this template to clone new VMs instantly.
--
--== Bash Script to Automate Setup ==
--
--Install the above using bash script below
--
--=== setup_proxmox_templates.sh ===
--
--{{code language="bash"}}

--
--After creating the VM and before making it into a template there are some programs and settings we want to ensure exists always.
--
--(% id="cke_bm_721114S" style="display:none" %)** **(%%)**clear bash history** to not leave any configuration in history, clear and disable history file before proceeding:

--{{code language="bash"}}
--unset HISTFILE
--export HISTSIZE=0
--export HISTFILESIZE=0
--
--sudo rm /.bash_history
--rm ~/.bash_history
--{{/code}}
--
--**qemu-guest-agent** is for allowing proxmox to query information from the VM such as IP address, shutdown commands, etc
--

--sudo apt install qemu-guest-agent -y
