[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-cim] Combined patch for Xen_HostedComputerSystem association
Attached is a combined patch that supports cross-namespace association for Xen_HostedComputerSystem. It includes Raj's filtering and my hacks for smash integration. Xen_ComputerSystem was also modified to only instrument root/cimv2. E.g. calling EnumInstanceNames on Xen_CS in namespace smash will return 0 instances. To use this patch, Xen_HCS and Xen_CS mof files must be imported to 'smash' namespace as well as root/cimv2. I have tested the patch quite thoroughly and ensured the correct namespace is set in object paths returned by provider. So what do you think? If this approach is acceptable, I will convert all effected associations (and their endpoints if appropriate) to use this mechanism. Jim diff -r 8e52de626fb5 src/Xen_ComputerSystem.c
