docs: broken command for vagrant & libvirt

[k8s-1]

Bug Report

Description

The command:
virsh list | grep vagrant | awk '{print $2}' | xargs -t -L1 virsh domifaddr
is broken if the parent directory is not called vagrant.

Suggested working alternative:
virsh list | grep node-* | awk '{print $2}' | xargs -t -L1 virsh domifaddr

Logs

`$ virsh list | grep -node- | awk '{print $2}' | xargs -t -L1 virsh domifaddr

Valid arguments are:

• ‘read’
• ‘recurse’
• ‘skip’
  Usage: grep [OPTION]... PATTERNS [FILE]...
  Try 'grep --help' for more information.
