TROUBLESHOOTING:\\
If vms don't come up maybe because a vagrant destroy was interrupted, this is a drastic solution that tends to work:

  virsh list --all
  virsh destroy <THE_MACHINE> 
  virsh undefine <THE_MACHINE> --snapshots-metadata --managed-save
  virsh vol-list default
  virsh vol-delete --pool default <THE_VOLUME>

  rm -f /var/lib/libvirt/images/* 
  systemctl restart libvirtd
  
  vagrant up
  vagrant ssh vmx-vcp-01
  
TROUBLESHOOTING AUTOMATED:\\

  virsh list --all  | egrep -v "Name|------" | awk '{print $2}' > /var/tmp/temp
