Installing Proxmox

Install from the 9.0 ISO

Flash the 9.0 ISO, boot, run the guided installer. After first login, immediately update packages from the UI or apt update && apt full-upgrade. (Proxmox VE 9.0 ISO Installer)

Choose a storage root that fits your plan

• ZFS root if you want snapshots, checksumming, easy clones, and you have enough RAM. The installer supports ZFS root and lets you select RAID at install time. (Storage - ZFS)

• Ext4 + LVM-Thin if you prefer lean host footprint and will keep most data on dedicated pools or NAS. LVM-Thin supports snapshots and clones too. (Storage - LVM-Thin)

Repos: enable No-Subscription on labs

If you do not have an enterprise key, enable the pve-no-subscription repo. It is fine for test and homelab use - not recommended for production. Configure it in /etc/apt/sources.list.d/proxmox.sources. (Package Repositories - No-Subscription)

Network - start simple

By default you get a Linux bridge like vmbr0. Attach your NIC and put VMs on that bridge. Add VLAN tags or a bonded uplink when needed. SDN is optional until you cluster. (Network Configuration)
