13:58:20 gbajson Hi, could anyone of you explain when Nova uses allocation values configured in nova.conf (e.g. cpu_allocation_rate), please?
13:58:40 gbajson As far as I understand, and tested, all allocation values are set in Placement
13:58:57 gbajson and values from nova.conf are being ignored.
14:00:05 sean-k-mooney cpu_allocation_rate cpu_allocation_ratio?
14:00:19 gbajson My bad, cpu_allocation_ratio
14:00:24 sean-k-mooney they need to be configured on the compute nodes
14:00:37 sean-k-mooney setting it on the contoler is nologer supported
14:01:08 sean-k-mooney before the intodcution of placment you coudl set tehm in the schdluer config but that is nolonger correct.
14:01:25 gbajson ok, but I have just unconfigured them completely on compute nodes, and I still control allocation rates through Placement
14:01:34 sean-k-mooney yes
14:01:37 gbajson so I am wondering if they are still used/needed
14:01:54 sean-k-mooney when they are not set it used the initial_allocation_*ratio values instead
14:02:24 sean-k-mooney https://docs.openstack.org/nova/latest/configuration/config.html#DEFAULT.initial_cpu_allocation_ratio
14:02:45 sean-k-mooney initial_cpu_allocation_ratio is use when first creating the RP
14:03:04 sean-k-mooney it defaults to 16
14:03:51 gbajson initial_cpu_allocation_ratio seems to be ignored too. By default it's 16.0 but I set up 2.0 through in Placement and I can only use 2* PCPUs on the compute node
14:03:56 sean-k-mooney initial_cpu_allocation_ratio will set the default value for the placment RP VCPU inventory allocation ratio
14:04:13 gbajson ok
14:04:27 sean-k-mooney it will not change the value of an existing RP
14:04:33 sean-k-mooney and it does not apply to PCPUs
14:04:47 sean-k-mooney PCPU inventories should always be set to 1.0
14:04:56 gbajson ok
14:05:42 sean-k-mooney so initial_*_allocation_ratio are ineteded for wehn you want to manage the ratios via the placment api
14:05:44 gbajson So, if I understand correctly, values set in Placement override cpu_allocation_ratio, right?
14:05:57 sean-k-mooney the *_allocation_ratios are for when you want to manage the values via the config
14:06:20 sean-k-mooney if cpu_allocation_ratio, is set it will orverride any value you set in plamcnet
14:06:26 sean-k-mooney back to the value in the config
14:06:39 sean-k-mooney if you want to manage it via placment cpu_allocation_ratio, should not be defiend
14:06:54 gbajson thanks
14:07:16 sean-k-mooney https://docs.openstack.org/nova/latest/admin/configuration/schedulers.html#allocation-ratios
14:08:06 sean-k-mooney the api driven approch is given as an example in the usage_senairos sectoin
14:08:09 sean-k-mooney https://docs.openstack.org/nova/latest/admin/configuration/schedulers.html#usage-scenarios
14:10:36 gbajson Is it possible *not to use Placement* in Rocky+ releases?
14:10:45 sean-k-mooney no
14:11:00 sean-k-mooney well not if you are using the filter schulder
14:12:04 sean-k-mooney the chance and caching schduler techniclaly dont need placment but neither should be used in production
14:12:37 gbajson OK, that explains all my concerns! Many thanks for help Sean
14:12:43 sean-k-mooney both are removed in later relases
14:12:48 sean-k-mooney no worries

#openstack-nova - 2020-08-11
01:43:44 ayoung Dumb idea time. Say I wanted to live migrate a VM from one openstack instance to another, across cluster boundaries. Would this be at all feasable?
02:23:24 sean-k-mooney ayoung: only by using libvirt directly and then manuly updating the db
02:23:36 sean-k-mooney ayoung: in other words no not really
02:23:46 sean-k-mooney ayoung: not in any way that would be supportable by nova
02:25:37 ayoung Of course it would be horrible. But so is leaving a cluster in place because it has key workloads.
02:26:35 ayoung So, yeah, diret libvirt would be necessary, and the receiving cluster would need to be able to take that running VM and make a database entry for it. On the old host, you would need to finish the migration and then set the VM into a non-runnable mode, too.
02:26:58 sean-k-mooney the eaiser approch would be to snapshot the vms and then copy the images and restore them on another cloud
