[Openstack] Accessing instance.flavor.projects fails due to orphaned Flavor

Hi, The flavor field of the Instance object is a lazy-loaded field and the projects field of the Flavor object is also lazy-loaded. Now it seems to me that when the Instance object lazy loads instance.flavor then the created Flavor object is orphaned [1] therefore instance.flavor.projects wil

With OVS driver, how can you even get a VM up and running in Openstack without the risk of melting the entire network down ? Both the interfaces of the BITW VM are sitting on br-int.The risk of BUM packets looping between the two interfaces is very high.   Even if the BITW VM does not forward

Hi, I have provided the answer to that on https://ask.openstack.org/en/question/101374 where you asked this question as well. That elaborates slightly on 'There are facilities to allow one VM or another to have CPU priority’ which James mentioned below. For RAM such things as Memory Tuning ht

Re: [Openstack] Openstack+KVM+overcommit, VM priority

2017-01-12 Thread Adam Lawson
This is a scheduler thing. Kvm/Linux has it's own scheduler built in for any process that needs to share CPU cycles aside from the filter scheduler used by OpenStack. My understanding is that any optimizations assigned to resource consumption will not be handled by OpenStack but with manual tweaks.

Re: [Openstack] Openstack+KVM+overcommit, VM priority

2017-01-12 Thread Adam Lawson
With 4 physical cpu cores, you'll have 8 with HT so you likely don't need anything managing overcommitting. But you also have memory contention in your design. OpenStack facilitates resource limits to prevent the contention from happening but does not get into managing vm priorities. The assumption

If you're running 100% coverage with dispersion report, then running it once per day seems reasonable. If you're running something smaller, like 1-10%, then doing it once per hour might be reasonable. The point is, make it automatic and integrate it into your normal ops metrics. Track it over

You don't need to run swift-dispersion-populate more than once - all it does is put a bunch of objects in some % of your ring's partitions. The number of partitions in a ring is fixed at creation [1] - only which device where each partition is assigned will change with a rebalance. swift-dispersi
