What is PVE Kernel Cleaner?

PVE Kernel Cleaner is a program to compliment Proxmox Virtual Environment which is an open-source server virtualization environment. PVE Kernel Cleaner allows you to purge old/unused kernels filling the /boot directory. As new kernels are released the older ones have to be manually removed frequently to make room for newer ones. This can become quite tedious and require extensive time spent monitoring the system when new kernels are released and when older ones need to be cleared out to make room. With this issue existing, PVE Kernel Cleaner was created to solve it.


  • Removes old PVE kernels from your system
  • Ability to schedule PVE kernels to automatically be removed on a daily/weekly/monthly basis
  • Run a simple pvekclean command for ease of access
  • Checks health of boot disk based on space available
  • Debug mode for non-destructive testing
  • Update function to easily update the program to the latest version
  • Allows you to specify the minimum number of most recent PVE kernels to retain
  • Support for the latest Proxmox versions and PVE kernels
