Linux list a KVM vm guest using virsh command nixCraft

How do I list a KVM vm guest using virsh command on a Linux based hypervisor?

A hypervisor is nothing but Linux kernel module that isolates operating systems and applications from the underlying server. KVM turn Linux operating system into a hypervisor. This post shows how to list an installed KVM guest VM using virsh command line option.

How to: Linux list a KVM vm guest using virsh command

The syntax is:
virsh list
virsh list --all
virsh list [options]

Examples

Let us see some command examples.

Just list domains / KVM VM guest

Simply type the command:
virsh list
OR
virsh list --all
Linux list a KVM vm guest using virsh command
Name is the name of the domain (KVM VM guest name). ID the domain numeric id. State is the run state as follows:

  1. running – The domain is currently running on a CPU.
  2. idle – The domain is idle, and not running or runnable. This can be caused because the domain is waiting on IO (a traditional wait state) or has gone to sleep because there was nothing else for it to do.
  3. paused – The domain has been paused, usually occurring through the administrator running virsh suspend. When in a paused state the domain will still consume allocated resources like memory, but will not be eligible for scheduling by the hypervisor.
  4. in shutdown – The domain is in the process of shutting down, i.e. the guest operating system has been notified and should be in the process of stopping its operations gracefully.
  5. shut off – The domain is not running. Usually this indicates the domain has been shut down completely, or has not been started.
  6. crashed – The domain has crashed, which is always a violent ending. Usually this state can only occur if the domain has been configured not to restart on crash.
  7. pmsuspended – The domain has been suspended by guest power management, e.g. entered into s3 state.

To list domains with autostart enabled

virsh list --autostart
Sample outputs:
