Host management tools provide essential functionality for maintaining and configuring your Proxmox VE host system. These scripts run directly on the Proxmox host and help automate common administrative tasks.

​
Container Management

​
Update LXC Containers

The update-lxcs.sh script provides an interactive way to update multiple LXC containers simultaneously. 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/update-lxcs.sh)"
  • Interactive container selection with whiptail interface
  • Option to skip stopped containers
  • Exclude specific containers from updates
  • Automatic detection of package manager (apt, apk, dnf, yum, pacman)
  • Color-coded status output
The script will prompt you to select which containers to skip and whether to update only running containers.

​
Cron-based Container Updates

Automate container updates with scheduled cron jobs: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/update-lxcs-cron.sh)"
This installs a weekly cron job that automatically updates all LXC containers.

​
Container Cleanup

Remove unused packages and clear cache from containers: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/clean-lxcs.sh)"

clean-lxcs.sh

Cleans package cache and removes unused packages from LXC containers

clean-orphaned-lvm.sh

Removes orphaned LVM volumes that are no longer associated with containers

​
Container Deletion

Safely delete LXC containers with confirmation: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/lxc-delete.sh)"

​
Post-Installation Configuration

​
Proxmox VE Post-Install

Optimize your Proxmox VE installation with recommended settings: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/post-pve-install.sh)"
  • Disable enterprise repository (if unlicensed)
  • Enable no-subscription repository
  • Configure apt sources correctly
  • Disable subscription nag dialog
  • Update and upgrade system packages
  • Install useful utilities
  • Configure automatic security updates (optional)

​
Proxmox Backup Server Post-Install

bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/post-pbs-install.sh)"

​
Proxmox Mail Gateway Post-Install

bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/post-pmg-install.sh)"

​
Kernel Management

​
Kernel Clean

Remove old kernel versions to free up disk space: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/kernel-clean.sh)"
Never remove your currently running kernel. The script automatically excludes the active kernel from removal.
The script:
  • Detects the currently running kernel
  • Lists all installed kernel versions
  • Allows interactive selection of kernels to remove
  • Safely removes selected kernel packages

​
Kernel Pin

Pin a specific kernel version to prevent automatic updates: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/kernel-pin.sh)"
Use this when you have a stable kernel and want to prevent automatic upgrades that might introduce issues.

​
System Optimization

​
Microcode Updates

Install and update CPU microcode for Intel and AMD processors: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/microcode.sh)"

Intel

Installs intel-microcode package and updates Intel CPU firmware

AMD

Installs amd64-microcode package and updates AMD CPU firmware

​
CPU Scaling Governor

Configure CPU frequency scaling for performance or power savings: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/scaling-governor.sh)"
Available governors:
  • performance: Maximum CPU frequency at all times
  • powersave: Minimum CPU frequency to save power
  • ondemand: Dynamic scaling based on load
  • conservative: Gradual frequency scaling

​
Hardware Acceleration

Enable hardware video acceleration for Plex, Jellyfin, and other media servers: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/hw-acceleration.sh)"
Supports:
  • Intel Quick Sync Video (QSV)
  • NVIDIA NVENC/NVDEC
  • AMD AMF/VCE
  • VAAPI

​

​
Backup and Restore

​
Host Backup

Create backups of important Proxmox host configuration: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/host-backup.sh)"
  • Backs up /etc/ directory by default
  • Custom directory selection available
  • Choose specific subdirectories to include
  • Creates compressed tar archives
  • Saves to custom location (default: /root/)

​

Monitoring

​
Monitor All

Automatically monitor and restart failed VMs and containers: 
bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/tools/pve/monitor-all.sh)"
This creates a systemd service that continuously monitors instances. Only instances tagged with mon-restart will be automatically restarted.
How to tag instances: 
# For VMs
qm set <vmid> -tags mon-restart

# For Containers
pct set <ctid> -tags mon-restart
Or use the Proxmox web UI: VM/CT → Options → Tags → Add “mon-restart”
