how could "virsh snapshot-list" with description

Question

virsh snapshot-create-as win7 snap01 --description "something here"

How could I list snapshots list with the description ?

Answer 1

I managed to do a simple bash script to list all VMs and the snapshots description:

#!/bin/bash

vmdomains=`sudo virsh list --all | sed 1,2d | awk '{ print $2 }'`

echo -ne "Domain\t\t\tSnapshot Name\t\t\tDescription\n"
echo "-----------------------------------------------------------------------------------------"
for vmdomain in $vmdomains; do
  echo -ne "$vmdomain\t\t"
  snapshots=`sudo virsh snapshot-list $vmdomain | sed 1,2d | awk '{ print $1 }'`
  snapshotflag=0
  for snapshot in $snapshots; do
    snapshotflag=1
    echo -ne "$snapshot\t\t"
    sudo virsh snapshot-dumpxml --domain $vmdomain --snapshotname $snapshot | grep "<description>" | sed 's/  <description>//' | sed 's/<\/description>//'
  done
  if [ $snapshotflag -eq 0 ]; then
    echo
  fi
done

Edit: Output example

~$ sh listsnap.sh 
Domain               Snapshot Name                  Description
-------------------------------------------------------------------------------------
Win10                Win10_Disabled_Updates         Used gpedit to disable updates
Win10                Win10_games_installed          Gaming Rig with passtrhough gpu
CentOS               CentOS_origin                  Installed Nginx and web dependencies
CentOS               CentOS_Wednesday               Installed Anaconda and Julia
CentOS               CentOS_weekend                 Updated PIP dependencies
Fedora
Ubuntu               Testing_nfs_Ubuntu             Configured nfs server

Edit: This was a quick script and may not handle all cases in the best way, see other scripts posted here for more detailed workaround. Also RHEL web console already shows snapshot descriptions Yay!
