2020-07-20 04:34:03 -0500 评论回答 Live migrate instances between different Hardware

Thanks for the reply, Exactly I did the same between intel Machines, it works but for AMD it seems to be a huge performance problem during live migration. Looking for alternatives, if we do a normal migration by shutting down a VM, will this parameters still needed?,cold migration case

2020-07-16 02:49:59 -0500 问了问题 Live migrate instances between different Hardware

Is there a way to live migrate instances between Intel and AMD nodes?

I know few parameters in nova.conf helps to migrate between old and new hardware and it worked for me before within intel hardware.

2019-08-01 07:31:19 -0500 问了问题 Hostnames to vms

I have my dns_domain parameter in neutron.conf, set to a domain name say (example.xxx). Now all the VM's from any project, getting the same domain name......My dns records have a different host name based on the project. For example project1 has a domain name (project1.kbr.xxx) and when a VM test1 is created my dns record shows http://test1.project1.kbr.com. But with in the VM hostname is like (test1.example.xxx) How can I see dns recordset hostnames as vm's hostnames?

If you are looking for a multinode controller and if i am correct in understanding it, you need to create a controller cluster, followed by database cluster and use HA proxy as a load balancer which will use hostname assigned to virtual ip for endpoints.

Yes, I do see it, if not with designate do we have any other solutions to achieve this, just curious

2019-06-26 02:22:39 -0500 问了问题 DNS integration in openstack

I am looking for a solution to integrate openstack (subnets,floating Ip's) to DNS, I tried with designate created a zone in project and able to get vm name as A record the moment vm is created. seems like designate works with separate zone in each project but what we are looking for is to have a same zone for all projects. Is there a solution to achieve this? I currently have a local bind within my controller and using forwarders to look in to our dns servers. if not with Designate what are the other alternatives to achieve this? I am using openstack pike, and having a three node controller cluster running designate. your inputs and advise is much needed and appreciated. Thanks in advance.

I don't see anything in server logs or agent logs its all like this for all pid's

2019-05-15 10:08:24 -0500 问了问题 Neutron consuming high CPU

I am running a 3 node controller cluster with haproxy and mysql galera, and two compute nodes in pike. Although there is no load, i see neutron consuming a high cpu, I searched in google but finding nothing, Any ideas on tuning will be much apreciated.

Each controller: CPU(s): 24 On-line CPU(s) list: 0-23 Thread(s) per core: 2 Core(s) per socket: 6 Memory : 94 GB

Compute nodes : CPU(s): 40 On-line CPU(s) list: 0-39 Thread(s) per core: 2 Core(s) per socket: 10 Memory : 250GB

pstree of neutron-server :

systemd(1)───neutron-server(9212)─┬─neutron-server(13855) ├─neutron-server(13856) ├─neutron-server(13857) ├─neutron-server(13859) ├─neutron-server(13861) ├─neutron-server(13862) ├─neutron-server(13863) ├─neutron-server(13865) ├─neutron-server(13867) ├─neutron-server(13869) ├─neutron-server(13870) ├─neutron-server(13873) ├─neutron-server(13875) ├─neutron-server(13877) ├─neutron-server(13878) ├─neutron-server(13879) ├─neutron-server(13882) ├─neutron-server(13883) ├─neutron-server(13886) ├─neutron-server(13887) ├─neutron-server(13888) ├─neutron-server(13891) ├─neutron-server(13892) ├─neutron-server(13893) ├─neutron-server(13894) ├─neutron-server(13897) └─neutron-server(13898)

Top command output :

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
13894 neutron 20 0 453812 138808 2248 R 89.5 0.1 713:54.25 /usr/bin/python2 /usr/bin/neutron-server --config-file /usr/share/neutron/neutron-dist.conf --config-dir /usr/share/neutron/server --c+

I read reducing report intervel of agents will help, any practical experiences?, please share on what exactly can be tuned without causing problems in future?

2019-03-19 10:05:31 -0500 评论回答 Floating IP parameter not visible in Horizon

Mohit that is not the case in pike, my dashboard has nothing like Access and security, Ideally it should be visible in Network or Instance drop down.

2019-03-19 05:29:44 -0500 问了问题 Floating IP parameter not visible in Horizon

Hi, I recently created a multi controller environment in openstack pike, Instances getting created with private IP from Dash board, I was able to add floating IP from console to Instances But can't see any option or parameter to add floating IP from dashboard, even with admin user. How can users add floating IP's from the dashboard?
