How to Install Proxmox VE 8 on Bare Metal

Proxmox VE 8 is an open-source virtualization platform — KVM + LXC, ZFS root, web UI, clustering — that runs the home lab and the small-to-medium DC alike. This guide installs it on bare metal in ~20 minutes.

Prerequisites

• A physical server (or hypervisor with nested virtualization enabled).
• CPU with VT-x/AMD-V — confirm in BIOS.
• ≥ 32 GiB disk; ≥ 8 GiB RAM (more = more VMs).
• USB stick or IPMI Virtual Media for the ISO.
• proxmox-ve_8.x-x.iso from proxmox.com/en/downloads.

Step 1: Write the ISO and boot

sudo dd if=proxmox-ve_8.x-x.iso of=/dev/sdX bs=4M status=progress conv=fsync

Boot from the stick → Install Proxmox VE (Graphical).

Step 2: Target disk and filesystem

Choose ZFS RAID if you have two or more matched disks (RAID-1 for a pair, RAID-Z1 for three+). For a single disk, ext4 is fine.

ZFS options worth knowing on the Advanced screen:

• ashift: 12 (4K sectors — modern default)
• compress: lz4 (huge win for VM disks)
• checksum: on (default, leave it)
• hdsize: leave full disk

Step 3: Country, timezone, password

• Country: Saudi Arabia (or where the host actually sits)
• Timezone: Asia/Riyadh
• Root password: 32+ chars
• Email: real address — the host will email you about failed backups

Step 4: Network

• Management interface: pick the NIC you will reach the web UI on
• Hostname (FQDN): pve01.lab.example.sa
• IP/CIDR: e.g. 10.0.10.5/24
• Gateway: 10.0.10.1
• DNS: 1.1.1.1

Step 5: First boot and the no-subscription repo

Proxmox ships an enterprise repo enabled by default that requires a subscription. For the free community use:

# Disable the enterprise repos
sed -i 's/^deb/# deb/' /etc/apt/sources.list.d/pve-enterprise.list
sed -i 's/^deb/# deb/' /etc/apt/sources.list.d/ceph.list 2>/dev/null || true

# Enable the community repo
echo 'deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription' \
  > /etc/apt/sources.list.d/pve-no-subscription.list

apt update
apt full-upgrade -y

Step 6: Reach the web UI and harden

Open https://10.0.10.5:8006/ in a browser. Log in as root@pam with the password you set.

Two quick hardening moves:

1. Create a non-root admin user. Datacenter → Users → Add → realm Proxmox VE authentication server → user ops → password.
2. Add a group + permission. Datacenter → Groups → Add admins; Datacenter → Permissions → Group Permission → /, admins, Administrator.

Now switch your daily logins to ops@pve and reserve root@pam for emergencies.

If the host is internet-facing, terminate the web UI behind a reverse proxy with TLS — never expose port 8006 to the world directly.

Verify

pveversion
pveversion -v | head
pvesm status
zpool status              # ZFS pool healthy
ip -brief address

Conclusion

A 20-minute install gets you a hypervisor with clustering, ZFS, a real backup story (Proxmox Backup Server integration), live migration if you add a second node, and a free community repo. From here every Proxmox guide on the internet applies verbatim.
