Hi all, I am trying to manage KVM remotely through Libvirt & CIM. I have Libvirt-CIM Providers and OpenPegasus CIMOM to acheive the same. When i tried to get the below values , i could not find any CIM or Libvirt-CIM classes for it. 1. IPSubnet Mask of Host machine 2. DefaultIPGateway of Host machine 3. MACAddress of Guest machines 4. Os Details of Guest Machines [ I need to know the CIM class for achieving this as well as Libvirt API methods to achieve the same.] Thanks in advance Mohan Sundar ________________________________ The contents of this e-mail and any attachment(s) may contain confidential or privileged information for the intended recipient(s).
