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  
19 -Download ubuntu 24 and create a template:
36 +== VM Template from Ubuntu Cloud Image ==
20 20  
21 -```
22 -wget http:~/~/cloud-images.ubuntu.com/releases/24.04/release/ubuntu-24.04-server-cloudimg-amd64.img
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"}}
23 23  qm create 910 -name template-ubuntu-jammy -memory 2048 -net0 virtio,bridge=vmbr0 -cores 2 -sockets 1
24 -qm importdisk 910 ubuntu-24.04-server-cloudimg-amd64.img nvm
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"}}
25 25  qm importdisk 910 ubuntu-24.04-server-cloudimg-amd64.img nvme
26 -qm set 910 -scsihw virtio-scsi-pci -virtio0 nvm:vm-910-disk-0
27 27  qm set 910 -scsihw virtio-scsi-pci -virtio0 nvme:vm-910-disk-0
28 -qm set 910 -scsihw virtio-scsi-pci -virtio0 unused0:nvme:vm-910-disk-0
29 -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"}}
30 30  qm set 910 -serial0 socket
31 31  qm set 910 -boot c -bootdisk virtio0
32 32  qm set 910 -agent 1
33 -qm set 910 -gotplug disk,network,usb
34 34  qm set 910 -hotplug disk,network,usb
35 35  qm set 910 -vcpus 1
36 -qm set 910 -vga qml
37 37  qm set 910 -vga qxl
38 -qm set 910 -ide2 nvm:cloudinit
39 39  qm set 910 -ide2 nvme:cloudinit
40 40  qm resize 910 virtio0 +8G
41 -qm set 910 -scsihw virtio-scsi-pci -virtio0 nvme:vm-910-disk-0
42 -qm importdisk ~-~-hwlp
43 -qm importdisk ~-~-help
44 -qm resize 9001 virtio0 +8G
45 -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"}}
46 46  qm resize 910 scsi0 +8G
83 +{{/code}}
84 +
85 +=== Convert the VM into a Template ===
86 +
87 +{{code language="bash"}}
47 47  qm template 910
48 -```
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 ===

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 +(% id="cke_bm_721114S" style="display:none" %)** **(%%)**clear bash history** to not leave any configuration in history, clear and disable history file before proceeding:
142 +
143 +{{code language="bash"}}
144 +unset HISTFILE
145 +export HISTSIZE=0
146 +export HISTFILESIZE=0
147 +
148 +sudo rm /.bash_history
149 +rm ~/.bash_history
150 +{{/code}}
151 +
152 +**qemu-guest-agent** is for allowing proxmox to query information from the VM such as IP address, shutdown commands, etc
153 +
154 +{{code language="bash"}}
155 +sudo apt update
156 +sudo apt upgrade -y
157 +sudo apt install qemu-guest-agent -y
158 +
159 +sudo systemctl enable qemu-guest-agent.service
160 +sudo systemctl start qemu-guest-agent.service
161 +{{/code}}
162 +
163 +**reset machine-id** to not have overlapping ids from same template
164 +
165 +{{code language="bash"}}
166 +cat /dev/null > /etc/machine-id
167 +cat /dev/null > /var/lib/dbus/machine-id
168 +{{/code}}
169 +
170 +**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.
171 +
172 +If you used a cloud-init base image it will have run the default cloudinit which installs and configures a bunch of s
