Enabling KAEzlib

Using the KAEzlib library during VM live migration requires to add the KAEzlib path to the VM XML file.

1. Check the XML configuration of the VM.

   virsh edit <VM_name>

2. Modify the XML file of the VM to replace the open source zlib library with KAEzlib.

   <qemu:commandline xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
       <qemu:env name='LD_LIBRARY_PATH' value='/usr/local/kaezip/lib:/usr/local/lib:$LD_LIBRARY_PATH'/>
   </qemu:commandline>

VMs do not require the configuration of huge pages. VMs configured with huge pages require additional adaptation for their live migration.
