Add a Let's Encrypt SSL certificate to the Proxmox web interface
Replace the self-signed Proxmox certificate with a free Let's Encrypt one using the built-in ACME client, with HTTP or DNS validation and automatic renewal.
Automate Proxmox with the REST API, pvesh and API tokens
Script Proxmox VE: explore the API with pvesh, call it remotely with curl and an API token, start VMs and clone templates, and keep automation credentials safe.
Back up and restore VMs and containers in Proxmox VE
Schedule backups of Proxmox VE VMs and LXC containers with vzdump, choose snapshot, suspend or stop mode, set retention, store backups off-host and restore them from the GUI or CLI.
Build a home lab for virtualization: hardware and software choices
Plan a home lab for learning virtualization: choosing CPU, RAM, storage and networking, mini PCs vs used servers, power and noise, and which hypervisor and first projects to start with.
Ceph storage for virtualization: RBD, clusters and planning
Learn how Ceph provides distributed block storage (RBD) for KVM and Proxmox VMs: monitors, OSDs, replication, hardware and network planning, and when Ceph is worth the complexity.
Configure Proxmox high availability (HA) for VMs
Make Proxmox VMs restart automatically on another node when a host fails: cluster and shared storage requirements, fencing, HA groups, adding resources and testing failover.
Create a cloud-init VM template in Proxmox VE
Build a reusable cloud-init template in Proxmox VE from an Ubuntu or Debian cloud image, set SSH keys and IPs per clone, and deploy new Linux VMs in seconds with qm commands.
Create a KVM virtual machine in Proxmox VE step by step
Create a Proxmox VM from an ISO: upload the image, pick CPU type, memory, VirtIO disk and network, install the OS through the console and add the QEMU guest agent.
Create a Windows Server template on KVM with Sysprep
Build a reusable Windows Server VM template on KVM or Proxmox: install drivers and updates, generalize with Sysprep, optionally add cloudbase-init, and clone new VMs with unique SIDs.
Create an LXC container in Proxmox VE
Download a container template and create an LXC container in Proxmox VE: unprivileged vs privileged, CPU, RAM and disk, networking, enabling nesting for Docker and starting it.
Import VMs from VMware ESXi into Proxmox VE
Move virtual machines from VMware to Proxmox: use the built-in ESXi import wizard or convert disks manually with qm importdisk, then fix drivers and networking.
Install and enable the QEMU guest agent in Proxmox VMs
Enable the QEMU guest agent so Proxmox can see VM IPs, shut down cleanly, freeze filesystems for consistent backups and run commands, on Linux and Windows guests.
Install Proxmox VE on a dedicated server
Install Proxmox VE step by step: download the ISO, choose ZFS or LVM storage, set networking, log in to the web UI on port 8006, configure repositories and create your first VM.
Install Proxmox VE on top of an existing Debian server
Install Proxmox VE on a Debian server when you cannot boot the ISO, such as a rented dedicated server: hostname setup, Proxmox repository, kernel, packages and bridge.
Install Windows 11 or Windows Server 2025 on Proxmox with TPM and UEFI
Create a Proxmox VM that meets Windows 11 requirements: OVMF UEFI with an EFI disk, a virtual TPM 2.0, VirtIO drivers during setup, and the guest tools afterwards.
Manage Proxmox ISO images and LXC container templates
Upload or download ISO images to Proxmox, fetch LXC templates with pveam, choose which storage holds them, and keep the template list tidy and up to date.
Manage Proxmox LXC containers: resources, mounts and unprivileged mode
Run Proxmox LXC containers well: privileged vs unprivileged, changing CPU, RAM and disk, bind mounts for shared data, nesting for Docker, and container backups.
Migrate Proxmox VMs between nodes (live and offline)
Move Proxmox VMs and containers between cluster nodes with live or offline migration, including local disks, and avoid the common CPU and storage pitfalls.
Pass a USB device through to a Proxmox VM
Give a Proxmox VM direct access to a USB device such as a licence dongle, Zigbee stick or UPS: pass by vendor/product ID or by port, and know the migration limits.
Proxmox command line cheat sheet: qm, pct, pvesm and pvecm
The Proxmox commands admins use daily: manage VMs with qm, containers with pct, storage with pvesm, clusters with pvecm, and backups with vzdump, with examples.
