This section discusses about disabling the Controller and SEs.

VMs and their corresponding images can be cleared using the following commands:

virsh undefine vm-name 
virsh destroy vm-name

At the root directory:

rm -rf /var/lib/libvirt/images/vm-name.qcow2 
 rm -rf vm-name 

The rm -rf vm-name command will delete the local folder created in root directory for the relevant VM.

  1. If at anytime if one sees the disk space of the host getting exhausted it might be due to the N number of qcow2’s being used in /var/lib/libvirt/images/ as part of the VM’s creation. Clear up any unused ones by deleting the respective VM and deleting the respective qcow2 image alongwith.

  2. Please ensure to manually cleanup (force-delete) the stale SE entries present in the Controller GUI post destroying SE VMs.
