Hi Tomas, I would expect bigger bandwidth I was in contact with SamYaple from the #openstack IRC channel who got 40Gigs/sec in his lab. The main difference between our environments: Me: · DPDK: NO · SR-IOV: NO · OS: Centos 7.3 (kernel 3.10) SamYaple: · DPDK

You might be able to force it by removing it from the active node and then adding it back. On Tue, Apr 18, 2017 at 3:56 PM, Sterdnot Shaken wrote: > Let's say I have 3 network nodes but set max_l3_agents_per_router to 2 > (intentionally) and I want to move either the active or standby router off

[Openstack] HA Router, "I want you!"

Let's say I have 3 network nodes but set max_l3_agents_per_router to 2 (intentionally) and I want to move either the active or standby router off of one of those nodes onto the 3rd network node… I can, using neutron l3-agent-router-remove and neutron l3-agent-router-add do this, but how do I delibe

[Openstack] Variable keystone token lifespans?

I use keystone tokens for two things: 1) To authorize a Horizon session. I like these to live a nice, long time so I don't have to re-auth with the web UI over and over. 2) To authorize service users running cron jobs and other maintenance scripts. These don't need to last long at all; just

[Openstack] Console security problem?

While doing some testing, I had something happen that is very concerning in regards to security. Below lays out the variables I'm working with: * MOS 9.2 * Openstack environment is using Cinder Block Device Driver (chose 'LVM' option vs 'Ceph' option when setting the block device option durin

[Openstack] ​[openstack-dev][mistral] failover/recovery and performance

Hi all. Do I understand correctly that mistral/ocata doesn't has a failover and recovery? I found two problems. First is in mistral-executor. 1. You need to run an action that executes for a long time. For example, std.sleep. 2. Kill mistral-executor where action executes. 3. Revive mistral-exec

Re: [Openstack] poor bandwidth across instances running on same host

Sorry to shatter you expectations, but those numbers are perfectly OK. I was testing on HPE DL380 gen9 with Intel Xeon E5-2630v3 and I got these speeds between two KVM VMs on the same host using netp

Re: [Openstack] VMs lost IP after running for few days on OpenStack Liberty.

Hi Dan, that normally should not happen. Presuming you are running Neutron, it may be two things – either your DHCP agent died and the instances could not renew their IPs, or the DHCP client inside them died, or as third variant, your RabbitMQ bus is broken and the DHCP agents don’t have actual
