Configuring a hotplug

In this section, we will see how to configure a hotplugging option in Proxmox virtual machines. Using the hotplugging feature, we can add and remove devices from a VM without restarting or power cycling the VM.

Getting ready

There are four device types that we can hotplug in a VM:

  • Disk
  • Network Interface Card (NIC)
  • CPU
  • Memory

As of Proxmox 3.4, we can only hotplug the CPU and memory, but cannot unplug them. Both the disk and Network Interface Card (NIC) can be hotplugged and unplugged. The following table shows the device types that are supported in different operating systems:

This is available for both OSes.

This is available for all versions of Linux/Windows.
