Yes, i think this is missing because the interface was designed with only libvirt in mind: the "reserved" field returns the amount of cache reserved only by VMs. So if there is another application on the same L3 socket with a cache reservation, "reserved" fails to report it. Eli can you expose the amount of free allocatable cache space (where non-free includes space used by other reservations) in a 'free_space' field in the cache output of virConnectGetCapabilities? -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
