with one query want to get meter samples OR statistics from ceilometer for more than one resource_id OR operand is not documented for ceilometer to support RESTFul queries for more than one resource_id.

Example, user want to query last sample for CPU meter for more than resource IDs.

Please guide, as how this can be achieved ?

2015-10-06 08:27:31 -0500 修改问题 Adding Ubuntu Image to XenServer Powered Openstack filesystem already mounted

I installed devstack on top of xenserver. Now I want to add a ubuntu image to openstack. I downloaded qcow2 image from here and used the guideline here to convert the image to vhd format and added to openstack using glance.

But when I start the instance, it got shut-off automatically. When I try to restart the instance in Xensenver, it got stuck at the messages:

[    1.612617] EXT4-fs (xvda1): mounted filesystem with ordered data mode. Opts: (null)
[    2.245259] EXT4-fs (xvda1): re-mounted. Opts: (null)

One thing to mention is I successfully added a cirros image to xenserver using the steps above, So what's the problem here? Could any one give any suggestions?

Thanks in advance!

2015-10-06 08:24:54 -0500 评论问题 Kilo - Adding second compute node

Hi, first : Please let us know about

#tail -f /var/log/{nova,neutron}/*.log

on both controller and compute nodes

second : on both compute nodes you get this error?

2015-10-02 00:04:15 -0500 回答问题 where AMQP is used in OpenVswitch

openvswitch is aneutron plugin module, when you install neuton-plugin-ml2-openvswitch or something like that on compute nodes and network nodes it installs the neutron-commmon component which has a /etc/neutron/neutron.conf file in that file you can mention the AMQ or Rabbitmq message passing method.

I hope you get the answer,

Your question needs to be more descriptive anyway!!

2015-10-02 00:00:04 -0500 评论问题 unable to login to dashboard

Have you ever login to openstack since you have install it? have you checked the keystone log? have you the login page or not?

2015-10-01 15:52:46 -0500 回答问题 How do I create an image in the dashboard clicking the "Create Image" button causes a failure?

make sure the glance is working

# netstat -ntlp |grep 9292
if the glance port is open then try
# service glance-api stop

then try again the netstat be sure the glance stops working sometimes It needs to be killed after that

# service glance-api start

in all steps monitor the logs.

sometimes the service shows that is working but it actually does not work (kind of weird) in those cases I stop the service and make sure the service is stopped. then I try:

# su glance
# glance-api

when running the glance-api it returns some logs and information on terminal which are always usefull to me

2015-10-01 15:07:41 -0500 回答问题 No valid host was found. Unable to launch instance in admin[KILO][UBUNTU 14.04]

This Error "No Valid Host Found" is a very generic Error it occurs when the nova-scheduler can not find any proper hypervisor regarding to resources you wanted, Even if you request more cpu cores more that the maximum available cpu cores on a server and it will return no valid host found.

This specific Error which you get comes from network allocation, I have this error for a long time and revised all of my configurations , Please before mess up and change anything go to controller node and revise the neutron server configurations It may not have sense first but I am pretty sure you have to check configurations on /etc/neutron/neutron.conf and /etc/neutron/plugins/ml2_plugin.ini and make sure you have the right configurations there.

Good luck

I have heard in Japanese keyboard characters they also have some issues with : character as well.

2015-09-29 22:11:18 -0500 回答问题 I am begin a beginner in Devstack

Your question does not sense, openstack is a IaaS solution and dev stack is a tool to install openstack easily and quickly for development causes,

you can install openstack on VM or dedicated server or what ever ...

but do not expect by installing openstack to get the SaaS because it is not for that type of cloud computing, I repeat it is a IaaS (Infrastructure as a service) solution, you can run any SaaS or PaaS on It.

I hope this helps :)

2015-09-29 21:48:51 -0500 评论问题 Glance Times out on Image-create

are you using ceph or filesystem for image saving?

2015-09-29 21:34:02 -0500 回答问题 no data received from console (juno)

Hi, novnc proxy works very great,

every instance on compute nodes on the start initiates a VNC port starting from 5900 and incrementally goes up novnc proxy configured in compute nodes to communicate to the controller node (no-vnc-proxy service) this service is a sort of abstraction between hypervisors vnc services and the clients who has accessed the instances using Horizon and delivers the service using the port 6080,

me myself have the same problem like you when I configured the servers both controller and compute node sides and restart the services

I mean every service related to openstack it did not work, I know it seems to be a little unprofessional but in my case I restarted the compute node and it worked I think there may be some backend services like libvirt which is involved with instance initiation .

I hope this helps

2015-09-29 21:22:12 -0500 回答问题 How to add space for glance service

Hi,

I suggest to change the glance mechanism from "Saving to files" to "Clustered RBD Mode" in this way you will need to install CEPH and add some HDDs all around your Servers and cluster every spare disks together this need refactoring the architecture but brings lots of flexibility with itself for example in your case instead of moving data from a disk to another or to mount a bigger hard disk you will install ceph client and install a separated storage servers in your server farm which are responsible for delivering the storage service.

you can have a look at the link below: ceph & glance configuration

Have in mind you should have active + clean state in ceph cluster.

2015-09-29 21:12:44 -0500 回答问题 any start guide for NEUTRON?

Hi SteCu, It really depends on operating system you are trying and the openstack version you wanna try, I tried Kilo on Ubuntu 14.04 and /juno on Debian wheezy and it worked properly here are the links:

2015-03-11 05:37:18 -0500 回答问题 How to shift my OpenStack environment completely into Fiber optics networking???

fiber optics and Ethernet cable are two different network medias actually these medias are not involved with openstack because they are OSI L2 interfaces if your operating system (Linux) has detected the fiber optic media, and your nodes are connected to each other there would be no problem for openstack which works in OSI L3 - L7 stacks,

with this change you have improved your BW from 1G to 10G which is a great improvement in speed of data transfer between nodes.

2015-02-18 05:36:48 -0500 回答问题 Openstack Grizzly Network Node

sure it is possible, separation of the networks is for better performance, you will lose some performance in that way, openstack networks in network node are:

1. management 
2. VM Data 
3. external

you can combine your external network with management or VM data , I suggest to combine external with management because there are very low traffic transferred in management network in network node "depends to your architecture"

Hi, I have successfully added two external subnets on an external network. However it is unclear to me when I set the gateway on a router to specify in which of the two subnets this should be done.

neutron net-show ext-net

with router-gateway-set I can specify the external net but not the subnet

neutron router-gateway-set [-h] [--request-format {json,xml}] [--disable-snat] router-id external-network-id

Any comment?

You should try neutron router-interface-add to add any network other than ext-net we add other interfaces using this command instead.

try:

neutron router-list
neutron net-list
neutron interface-list 'ROUTER_ID'
neutron router-interface-add 'NET_ID'

I suggest you to follow exactly step by step the original juno/debian manual which version of debian are you using the manual is working with wheezy.

another cause to this problem may be in your repository and package lists it is important that the packages are coming from which repo in this case I suggest you to revise the very first steps in basic ENV. in the manual.

also leave here :

service neutron-plugin-openvswitch-agent status
service openvswitch-switch status
service neutron-l3-agent neutron-dhcp-agent status

so the problem can be analyzed.

I use the same command to get the debuge message, but don't understand what is the problem?

also there is another error above which is about database update

I really suspect the new version of nova-compute and neutron-plugin-openvswitch-agent:

I did not have any problem with the 2014.2-4~bpo70+1 version but 2014.2.1-4~bpo70+1 faces this problem.

please help.
