Follow through this guide to learn how to list running and stopped vms on KVM. KVM, an acronym for Kernel-based Virtual Machine, is an open source virtualization technology built into Linux. Specifically, KVM lets you turn Linux into a hypervisor that allows a host machine to run multiple, isolated virtual environments called guests or virtual machines (VMs).

So you could be using KVM to run your virtual machines and wondering how you can list running and stopped VMS? Well, as much as it is possible to get this information from the KVM UI, the terminal centric nerds can also be able to obtain the same information from the command line.

List Running and Stopped VMS on KVM

KVM ships with a command line tool called virsh, which is the main interface for managing virsh guest domains. The program can be used to create, pause, and shutdown domains. It can also be used to list current domains.

Therefore, to list running and stopped vms on KVM, use the virsh command with the domain monitoring option, list.

The basic command syntax is;

virsh list
virsh list [OPTION]

Where [OPTION] can be one of the very many options as shown in the help page. See below output from virsh list --help.

  NAME
    list - list domains

  SYNOPSIS
    list [--inactive] [--all] [--transient] [--persistent] [--with-snapshot] [--without-snapshot] [--with-checkpoint] [--without-checkpoint] [--state-running] [--state-paused] [--state-shutoff] [--state-other] [--autostart] [--no-autostart] [--with-managed-save] [--without-managed-save] [--uuid] [--name] [--table] [--managed-save] [--title]

  DESCRIPTION
    Returns list of domains.

  OPTIONS
    --inactive       list inactive domains
    --all            list inactive & active domains
    --transient      list transient domains
    --persistent     list persistent domains
    --with-snapshot  list domains with existing snapshot
    --without-snapshot  list domains without a snapshot
    --with-checkpoint  list domains with existing checkpoint
    --without-checkpoint  list domains without a checkpoint
    --state-running  list domains in running state
    --state-paused   list domains in paused state
    --state-shutoff  list domains in shutoff state
    --state-other    list domains in other states
    --autostart      list domains with autostart enabled
    --no-autostart   list domains with autostart disabled
    --with-managed-save  list domains with managed save state
    --without-managed-save  list domains without managed save
    --uuid           list uuid's only
    --name           list domain names only
    --table          list table (default)
    --managed-save   mark inactive domains with managed save state
    --title          show domain title

In this tutorial, we are only interested in listing KVM guest vms that are either in running, stopped/shutoff, or paused state.

List Running VMS on KVM

By default, when you run virsh list command with no other option, it lists currently running or paused vms;

virsh list
 Id   Name                State
-----------------------------------
 5    ubuntu20.04-clone   paused
 6    ubuntu20.04         running

If you want to explicitly list running vms, then run the command below;

virsh list --state-running
 Id   Name          State
-----------------------------
 6    ubuntu20.04   running

You can also get the vms in various states, including the running state by using the --all option.

virsh list --all
 Id   Name                State
------------------------------------
 5    ubuntu20.04-clone   paused
 6    ubuntu20.04         running
 -    kolla-ansible       shut off

List Stopped VMS on KVM

To list stopped KVM virtual machines, you can pass the --state-shutoff option to virsh list command.

virsh list --state-shutoff
 Id   Name            State
--------------------------------
 -    kolla-ansible   shut off

Similarly, you can use the –all option to check vms in all states, including stopped vms;

virsh list --all
 Id   Name                State
------------------------------------
 5    ubuntu20.04-clone   paused
 6    ubuntu20.04         running
 -    kolla-ansible       shut off

You can list other states of the KVM virtual machines by passing specific state option to virsh list command.

That is how easy it is to list running or stopped vms on KVM.
