8 += Getting Started with Proxmox VE LXC and VM Templates =
10 10  
11 -```
10 +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.
11 +
12 +== LXC Templates ==
13 +
14 +LXC containers are lightweight and ideal for running Linux services with minimal overhead.
15 +
16 +=== List Available Templates ===
17 +
18 +To view the available LXC templates:
19 +
20 +{{code language="bash"}}
12 12  pveam list
22 +{{/code}}
23 +
24 +=== Download Templates ===
25 +
26 +Use the pveam download command to import templates to the local storage:
27 +
28 +{{code language="bash"}}
13 13  pveam download local ubuntu-22.04-standard_22.04-1_amd64.tar.gz
14 14  pveam download local ubuntu-24.04-standard_24.04-1_amd64.tar.zst
15 15  pveam download local debian-12-standard_11.7-1_amd64.tar.zst
32 +{{/code}}
16 16  
17 -```
34 +Once downloaded, these templates can be used to create new LXC containers from the Proxmox web interface or via CLI.
18 18  
36 +== VM Template from Ubuntu Cloud Image ==
37 +
38 +KVM VMs are ideal when you need full virtualization, for instance, to run Windows or more complex Linux systems.
39 +
40 +=== Download Ubuntu Cloud Image ===
41 +
42 +Download the official Ubuntu 24.04 cloud [[image:]]
43 +
44 +{{code language="bash"}}
45 +wget http://cloud-images.ubuntu.com/releases/24.04/release/ubuntu-24.04-server-cloudimg-amd64.img
46 +{{/code}}
47 +
48 +=== Create the Virtual Machine ===
49 +
50 +Create a new VM with ID 910 (you can pick any unused ID):
51 +
52 +{{code language="bash"}}
53 +qm create 910 -name template-ubuntu-jammy -memory 2048 -net0 virtio,bridge=vmbr0 -cores 2 -sockets 1
54 +{{/code}}
55 +
56 +=== Import and Attach the Disk ===
57 +
58 +Choose the correct storage (replace nvme if you use a different storage name):
59 +
60 +{{code language="bash"}}
61 +qm importdisk 910 ubuntu-24.04-server-cloudimg-amd64.img nvme
62 +qm set 910 -scsihw virtio-scsi-pci -virtio0 nvme:vm-910-disk-0
63 +{{/code}}
64 +
65 +=== Configure the VM ===
66 +
67 +{{code language="bash"}}
68 +qm set 910 -serial0 socket
69 +qm set 910 -boot c -bootdisk virtio0
70 +qm set 910 -agent 1
71 +qm set 910 -hotplug disk,network,usb
72 +qm set 910 -vcpus 1
73 +qm set 910 -vga qxl
74 +qm set 910 -ide2 nvme:cloudinit
75 +qm resize 910 virtio0 +8G
76 +{{/code}}
77 +
78 +
79 +If your disk is using SCSI instead of virtio, resize like this:
80 +
81 +{{code language="bash"}}
82 +qm resize 910 scsi0 +8G
83 +{{/code}}
84 +
85 +=== Convert the VM into a Template ===
86 +
87 +{{code language="bash"}}
88 +qm template 910
89 +{{/code}}
90 +
91 +Now you can use this template to clone new VMs instantly.
92 +
93 +== Bash Script to Automate Setup ==
94 +
95 +Install the above using bash script below
96 +
97 +=== setup_proxmox_templates.sh ===
98 +
99 +{{code language="bash"}}
100 +#!/bin/bash

137 += VM runtime setup =
138 +
139 +After creating the VM and before making it into a template there are some programs and settings we want to ensure exists always.
140 +
141 +**qemu-guest-agent** is for allowing proxmox to query information from the VM such as IP address, shutdown commands, etc
142 +
143 +{{code language="bash"}}
144 +sudo apt update
145 +sudo apt upgrade -y
146 +sudo apt install qemu-guest-agent -y
147 +
148 +sudo systemctl enable qemu-guest-agent.service
149 +sudo systemctl start qemu-guest-agent.service
150 +{{/code}}
151 +
152 +**reset machine-id** to not have overlapping ids from same template
153 +
154 +{{code language="bash"}}
155 +cat /dev/null > /etc/machine-id
156 +cat /dev/null > /var/lib/dbus/machine-id
157 +{{/code}}
158 +
159 +**clear bash history** to not leave any configuration in history
160 +
161 +
162 +**cloud-init** is a great hook for installing or configuring programs or receiving variables from cloudinit CDROM drive. Making it easier to change IP, hostname, DNS, username/password, etc between VMs
163 +
164 +{{code language="bash"}}
165 +cloud-init clean
