In Linux Proxmox
What Does qm Stand For?
In Proxmox, qm stands for Qemu Manager.
It’s the Proxmox command-line tool for managing QEMU/KVM virtual machines. The qm tool lets you:
- Create VMs (
qm create) - Configure them (
qm set,qm config) - Start/stop VMs (
qm start,qm shutdown,qm stop) - Attach disks, ISOs, network cards, etc.
- Access the VM monitor for low-level commands (
qm monitor)
So when you run:
```bash
qm create 110 –name win11 …
You’re telling Proxmox’s QEMU Manager to create a VM with ID 110 using QEMU/KVM as the backend.
