Actually, I only expose the contiguous cache which can be allocated to VMs for now. so free == max_contiguous. Othere will be one case: schemata 1 = 1000 0000 schemata 2 = 0010 0000 default schemata should be 0001 1111 (schemata should be contiguous, so it can’t be 01011111 and free_size = 5 * min_cache_unit virsh nodecachestats will report free=5 * min_cache_unit next if a new vm requires cache of 1 * min_cache_unit schemata 1 = 1000 0000 schemata 2 = 0010 0000 new VM’s schemata = 0100 0000 default schemata should be 0001 1111 so free_size is still 5 * min_cache_unit. and virsh nodecachestats will report free=5 * min_cache_unit I am not sure if that will meaningful to user we expose (fragmented) cache which can not be allocated to VMs.
