How to use the command "qm monitor" (with examples)
The qm monitor command is used to enter the QEMU Monitor interface, which is a command-line interface for managing and controlling virtual machines. It provides direct access to the emulator and allows for real-time interaction with the virtual machine. This article will illustrate three use cases of the qm monitor command.
Use case 1: Enter the QEMU Monitor interface of a specific virtual machine
Code:
qm monitor vm_id
Motivation:
This use case is useful when you need to directly interact with a specific virtual machine’s emulator to perform troubleshooting, debugging, or advanced configuration tasks. By entering the QEMU Monitor interface, you can have low-level control over the virtual machine and access various monitor commands.
Explanation:
qm monitor: The command to enter the QEMU Monitor interface.vm_id: The ID of the virtual machine for which you want to enter the QEMU Monitor interface.
Example output:
When running the command qm monitor 100, you will enter the QEMU Monitor interface of the virtual machine with ID 100. From here, you can execute monitor commands specific to the virtual machine, such as modifying device configurations or inspecting virtual machine state.
