[ops] [nova] Wrong reported memory hypervisor usage
In the dashboard of my OpenStack Ocata cloud I see that the reported memory usage is wrong for the hypervisors. As far as I understand that information should correspond to the "used_now" field of the "nova host-describe" command. And indeed considering an hypervisor: # nova host-describe cld-blu-01.cloud.pd.infn.it +-----------------------------+----------------------------------+-----+-----------+---------+ | HOST | PROJECT | cpu | memory_mb | disk_gb | +-----------------------------+----------------------------------+-----+-----------+---------+ | cld-blu-01.cloud.pd.infn.it | (total) | 8 | 32722 | 241 | | cld-blu-01.cloud.pd.infn.it | (used_now) | 19 | 16259 | 23 | | cld-blu-01.cloud.pd.infn.it | (used_max) | 19 | 38912 | 95 | | cld-blu-01.cloud.pd.infn.it | b08eede75d5e4be4b0fe21e68fa9c688 | 1 | 2048 | 20 | | cld-blu-01.cloud.pd.infn.it | 7890b3e262264529a19f9743cf2f14bc | 16 | 32768 | 50 | | cld-blu-01.cloud.pd.infn.it | 4d8187cffa6a4085ad4a357b8a5afc03 | 2 | 4096 | 25 | +-----------------------------+----------------------------------+-----+-----------+---------+ So for the memory it reports 16259 for used_now, while as far as far I understand it should be 38912 + the memory used by the hypervisor Am I missing something ?

As far as I understand that information should correspond to the "used_now" field of the "nova host-describe" nova host-describe has been removed in later version of nova. command.

understand it should be 38912 + the memory used the hypervisors api's memory_mb_used is (reserved memory + total of all memory associtate with instance on the host). i would have expected used_now to reflect that. what does "openstack hypervisor show cld-blu-01.cloud.pd.infn.it" print.

Could it be that you are hitting this bug: https://bugs.launchpad.net/nova/+bug/1733034 If you are affected by this bug you will see the memory usage change between the "sum of all instances + reserved memory" and the actual usage on the hypervisor as reported by libvirt. Just call "nova hypervisor-show " a few times to see the values change. depending on which version you are running, you have to create or destroy an instance to see the changing values. Gaudenz

So for the memory it reports 16259 for used_now, while as far as far I
by the hypervisor
Am I missing something ?
understand it should be 38912 + the memory used the hypervisors api's memory_mb_used is (reserved memory + total of all memory associtate with instance on the host). i would have expected used_now to reflect that. what does "openstack hypervisor show cld-blu-01.cloud.pd.infn.it"
