Re: [Openstack-operators] Openstack Version discovery with the cli client.

Hi Saverio, I think only the API versions supported by some of the endpoint are discoverable, as described here: https://wiki.openstack.org/wiki/VersionDiscovery curl https://x.x.x.x:9292/image curl https://x.x.x.x:8774/compute Cheers, George On Tue, Aug 7, 2018 at 9:30 AM, Saverio Proto

Re: [Openstack-operators] attaching network cards to VMs taking a very long time

We use "vif_plugging_is_fatal = False" and "vif_plugging_timeout = 0" as well as "no-ping" in the dnsmasq-neutron.conf, and large rally tests of 500 instances complete with no issues. These are some good blogposts about Neutron performance:

Re: [Openstack-operators] Guest crash and KVM unhandled rdmsr

Hi Blair, We had a few cases of compute nodes hanging with the last log in syslog being related to "rdmsr", and requiring hard reboots: kvm [29216]: vcpu0 unhandled rdmsr: 0x345 The workloads are probably similar to yours (SGE workers doing genomics) with CPU mode host-passthrough, on top of

Re: [Openstack-operators] Experience with Cinder volumes as root disks?

I totally agree with Jay, this is the best, cheapest and most scalable way to build a cloud environment with Openstack. We use local storage as the primary root disk source which lets us make good use of the slots available in each compute node (6), and coupled with the Raid10 gives good I/O

Re: [Openstack-operators] Mixed env for nova (ceph for some compute nodes, local disk for the rest): qcow2 or raw images ?

Hi Massimo, You can upload the images twice, in both qcow2 and raw format, then create a host aggregate for your "local-disk" compute nodes and set its metadata to match the property you'll set on your qcow2 images. When somebody will start a qcow2 version of the image, it will be scheduled on

the console. You could create a special role that has console access and change the policy file to reference that role for the "compute:get_vnc_console", for example. I don't think you can do it on per-flavor basis. Cheers, George On Thu, Oct 27, 2016 at 10:24 AM, Blair Bethwaite <blair.bethwa.
