[Libvirt-cim] Xen Domain Management CIM-Provider

[Tej]

I am trying to understand the provider implementation for Xen VM
lifecycle management.
Does the xen provider (libvirt/xen-cim) uses the xenstore to
access/change the configuration information regarding the domains.
e.g if Xen Client has to changes the memory allocation for any of the
domain (i assume discover of domain/UUID/domid is already done)  then
can it uses xenstore to perform the operation in following way.

*xenstore-write /local/domain/domid/memory/target  <value> (balloon watch node)*
Or Is there any other method to perform the same operations.

thanks in advance for any information or pointers
