[Openstack] Fwd: [Quantum] Public Network spec proposal

[Yong Sheng Gong]

If we just use one flag, it can represent just two values True or False. If we want to represent three values True, False or not specified, we have to use --public True or --public False or nothing at all.So it is a three-values logic.-openstack-bounces+gongysh=cn.ibm@lists.launchpad.net wrote: -To: openstack@lists.launchpad.netFrom: Endre Karlson Sent by: openstack-bounces+gongysh=cn.ibm@lists.launchpad.netDate: 07/12/2012 07:53PMSubject: [Openstack] Fwd:  [Quantum] Public Network spec proposalWhy not just --public or not ? Why do you need --public True ? That just adds confusion...Endre.

Hi,
1. Is this also applicable to the agents? Say for example a user
wants to ensure that a public network is attached to network
interface em1 and the private network attached to em2. Is this
something that will be addressed by the blueprint?
2. I prefer option #3. This seems to be a cleaner approach for the
user interface.
Thanks
Gary

I don't know exactly why, and probably that does not even matter, as setattr globally alters the value of flag, and we probably don't want this to happen anyway.The value of the flag can be altered for a single test case using the following syntax:self.flags(flat_injected=True)

Hi Yong,I have been able to reproduce the error on my dev machine - I couldn't earlier on because I was tesyinh the test_xenapi module only, and no failure occured.It seems that test_quantumv2 is the root cause. If you look at gerrit, Jenkins started complaining when you first added that module.

Indeed, if you rename it to _test_quantumv2, the error disappears.I guess the problem is that quantum_v2 apparently is the only test modules whose test cases do not inherit from nova.test. I am trying to understand what exactly causes then the failure in test_xenapi. My gut says it must have something to do with mox, but I will let you know soon - unfortunately each test run takes almost 10 minutes!

2) Predictable code review effort for core devs3) The PTL knows who should be whipped!I think we can leverage the fact that our core devs span several time zones. So for each day we can have, for instance, an EMEA core reviewer on duty between 1AM and 9AM PST, an US core reviewer on duty between 9AM and 5PM PST, and an APAC core reviewer on duty between 5PM and 1AM PST.
Of course the plan needs to be flexible especially around milestone release, where all the devs which are not busy coding should probably dedicate more time to code review.I am going to start a wiki page with a 5x3 grid, with days on the rows and zones on the columns. If you like this idea, +1 this email and add your name to the grid :)
Otherwise, please let me have your feedback and concerns.Salvatore

All, 
My issue is close to what reported by Emilien and others in
https://answers.launchpad.net/quantum/+question/197701. Only
difference is that instead of not receiving DHCP reply, I do see
the DHCP reply from GW interface, but I still can not ping/ssh to
the VM.
My server configuration is same as what Emilien has described in his
document here

https://github.com/EmilienM,
the only difference is that I'm using a third interface (eth2) to
connect quantum networks on two servers. And the eth1 is used for
management traffic.

My network configuration is

No ARP response from the VM. I tried to login to the VM console by

[Openstack] About openstack common client

[Yong Sheng Gong]

 Hi,I just want to ask about the relationship among openstackclient https://launchpad.net/python-openstackclient and other clients.Will openstackclient replace other clients ( such as quantum client, keystone client, nova client, xx) or just a supplement?by now, the openstackclient is calling codes from other clients, so it seems it is just another client wrapper. In this case, we will have to implement two set of front codes to call specific client. One will be in openstackclient, and one will be in separate client itself.ThanksYong Sheng Gong

Re: [Openstack] [Netstack] Want to start Keystone support for Quantum Client

[Yong Sheng Gong]

Hi, 
How can I help with the common openstack client? I think quantum needs 
its own client to be implemented first and then common openstack client 
(just as a thin wrapper) can call the client module if we have quantum 
client designed as nova client.

  Hi everyone,

I'm trying to configure a multi-node installation. Here is a
brief overview.

1) controller - api+network+scheduler+novnc+glance+keystone
(nova.conf - http://paste.openstack.org/show/17470/)
2) compute node (nova.conf - http://paste.openstack.org/show/17469)
3) volume node(single)

Compute and vnc are working fine. I'm able to create and
delete volumes. Iscsi discovery from the compute nodes is
working too. But when I try to attach a volume, the compute
node tries to connect to the controller node instead of
volume and hence crashes with the following error.

Re: [Openstack] Understanding Integration Bridge and MACs

[Yong Sheng Gong]

 Hi,You observation is right. We keep different parts of quantum network info in nova db and quantum db. Quantum client just removes record in quantum db, while nova-manage network way will removes record in nova db, after that it will call quantum server's api to delete record in quantum. As far as I know, the whole quantum network will move to quantum totally, after that you will not have this problem.

Re: [Openstack] Accessing VMs in Flat DHCP mode with multiple host

[Yong Sheng Gong]

HI,First you have to make sure the network between your control node's br100 and your compute node's br100 are connected. and then can you show the output on control node:ps -ef | grep dnsmasqbrctl showifconfig2. can you login to your vm by vnc to see the eth0 configuration and then try to run udhcpc?Thanks-openstack-bounces+gongysh=cn.ibm@lists.launchpad.net wrote: -To: "openstack@lists.launchpad.net" openstack@lists.launchpad.netFrom: Michaël Van de Borne michael.vandebo...@cetic.beSent by: openstack-bounces+gongysh=cn.ibm@lists.launchpad.netDate: 05/10/2012 09:03PMSubject: [Openstack] Accessing VMs in Flat DHCP mode with multiple host
  


  
Hello,

I'm running into troubles accessing my instances.
I have 3 nodes:
1. proxmox that virtualizes in KVM my controller node
 1.1 the controller node (10.10.200.50) runs keystone, nova-api,
network, scheduler, vncproxy and volumes but NOT compute as it is
already a VM
2. glance in a physical node
3. compute in a physical node

my nova.conf network config is:
--dhcpbridge_flagfile=/etc/nova/nova.conf
  --dhcpbridge=/usr/bin/nova-dhcpbridge
  --routing_source_ip=10.10.200.50
  --libvirt_use_virtio_for_bridges=true
  --network_manager=nova.network.manager.FlatDHCPManager
  --public_interface=eth0
  --flat_interface=eth1
  --flat_network_bridge=br100
  --fixed_range=192.168.200.0/24
  --floating_range=10.10.200.0/24 
  --network_size=256
  --flat_network_dhcp_start=192.168.200.5
  --flat_injected=False
  --force_dhcp_release
  --network_host=10.10.200.50

I even explicitly allows icmp and tcp port 22 traffic like this:
euca-authorize -P icmp -t -1:-1 defaulteuca-authorize -P tcp -p 22 default
before setting
  these rules, I was getting 'Operation not permitted' when pinging
  the VM from the compute node. After setting these, I just get no
  output at all (not even 'Destination Host Unreachable')

  
  The network was created like this:
  nova-manage network create private
  --fixed_range_v4=192.168.200.0/24 --bridge=br100
  --bridge_interface=eth1 --num_networks=1 --network_size=256
  
  However I cannot ping or ssh my instances once they're active. I
  have already set up such an Essex environment but the controller
  node was physical. Morevover, every examples in the doc presents a
  controller node that runs nova-compute.
  
  So I'm wondering if either:
  - having the controller in a VM
  - or not running compute on the controller
  would prevent things to work properly.
  
  What can I check? iptables? is dnsmasq unable to give the VM an
  address? 
  
  I'm running out of ideas. Any suggestion would be highly
  appreciated.
  
  Thank you,
  
  michaël

If you want to provide your own addresses to instances, I believe you will need to extend nova codeto provide your custom IP address in API request, and then if it's not already allocated, it should get allocated.

 And then I couldn't ssh or ping the instance from other server with the same subnet.
 What is the problem ? I checked the iptables policies on the compute host, and find nothing about the DROP packets.
 I also tried to changed the record from nova.fixed_ips table and libvirt.xml of the instance, then reboot the instance, still not worked.
 I used FlatDHCP as my network manager.
You can't do this. Libvirt sets up no mac spoofing and no ip spoofing so the ip address needs to match the dhcp'd one. You should be able to switch to a static and use the same info that you get from dhcp though.
 2. According to the first question, I have another requirement to set up a loopback IP address (lo:0) on the running instance, after setting was completed,I couldn't ping or ssh the loopback IP from the same subnet, and I tried to set a alias IP address with eth0:0, but still not get worked. Any ideas with this ?
Not sureI guess it's the same issue as with setting a different IP from what dnsmasq provided. You can try ebtables -F; ebtables -t nat -F to flush those anti spoofing rules. 


 3. Is there any way to use 2 NICs with different subnets on instances? I want to separate the network traffic.
 Now I'm running with one bridged interface (br100), and it works well. In order to backup the large log files,
 I'm planing to use 2 NICs for the compute hosts, I want use 2 vNICs on instance, one for web service and the other for log backup,
 I think I should create a new network for the second bridged interface, but I can't find any document to guild me.
This is definitely possible with FlatManager (You could use cloud_config drive and some version of contrib/openstack-config converted to work with centos to set up the interfaces)
It was possible at one point with FlatDHCPManager as well by creating multiple networks and using a specific combination of config options like use_single_default_gateway. I don' t know if anyone has tried this for a while so there may be issues with it. You might try creating a second network and setting use_single_default_gateway and see what

So, i created 2 pools of floating ips, one for each network (so that I could associate guest VMs appropriately based on the host they are launched on). From the dashboard, i launched a VM. It was successful and showed the private ip address. But, the UI does not show on which node it was launched on. Without this information, I am not able allocate/associate the floating ip from appropriate pool.

Re: [Openstack] How to setup vncproxy with ubuntu precise package?

[Yong Sheng Gong]

Hi, please see if following text can help.
			To enable vnc console access VMs started by OpenStack, we need many components to collaborate.
		
Components on control node

		nova-api, which is API server of OpenStack
		nova-consoleauth, which is used to authorize vnc client
		noVNC, which is a VNC proxy for browser. An alternative proxy is 
nova-xvpvncproxy, which can accessed by a Java client at 
https://github.com/cloudbuilders/nova-xvpvncviewer.
			
Components on compute node

		nova-compute, which is nova binary to instantiate VMs
		libvirt driver, which is used by nova-compute to interact with libvirt server
		VNC server, which is part of hypervisor?
			
		
			Steps for user to access VNC console
		
			
			1. user gets the vnc console by command：
		
			

	
		[root@robinlinux utils]# nova get-vnc-console myserver20 novnc
		

			
		
	
	
		nova-api accepts this request, and then sends out "get_vnc_console" message to VM's related compute host
	
		2. nova-compute, running on that compute host accepts that message, 
generate a token and call libvirt driver's get_vnc_console methods.
	
		3. Libvirt driver will connect with libvirt server to get VM's vnc 
port, and look up the vnc host from FLAGS.vncserver_proxyclient_address.
	
		4. nova-api will send out "authorize_console" message to 
nova-consoleauth, which then caches the connection information returned 
by compute-node with token as key
	
		5. user browsers the URL returned the previous command, like below:
	
		
			

	[root@robinlinux utils]# nova get-vnc-console myserver20 novnc
	+---+--+
	| Type | Url |
	+---+--+
	| novnc | http://controlnode:6080/vnc_auto.html?token=34ce7a44-6186-43d8-be14-2ea9e028b8fa |
	+---+--+
	
			
		
	
	
		6. noVNC, which is listening on 6080 HTTP port, accepts the URL request, sends out "check_token" message to nova-consoleauth
	
		7. nova-consoleauth checks the cached connections and returns one according to the requested token key
	
		8. noVNC begins the proxy work, connecting the VNC server
	
		About configuration items in nova.conf
	
		
			

	#read by nova-compute to compose vnc-console URL
	# for novnc
	novncproxy_base_url=http://controlnode:6080/vnc_auto.html
	# for xvpvnc
	xvpvncproxy_base_url=http://controlnode:6081/console
	#read by nova-compute to instantiate VMs
	vncserver_listen=controlnode

 I haven't fixed this yet because I'm not sure if the $(tenant_id)s is
 literal or which tenant_id specifically to use (the Service tenant for the
 adminurl possibly)?
The _expression_ "$(tenant_id)s" is really contained inside the pattern
in the database. It is substituded with a specific tennant ID when
an application makes its request. The weird syntax is inherited from
Python, where one can use constructs like %s or %(key)s.

If you launched this instance before you specified --vncserver_listen, then the instance's vnc server will bind 127.0.0.1. Furthermore, this configuration will be baked into the instances libvirt.xml file, so changes to --vncserver_listen in your nova.conf will not have any effect for already existing instances.
Did you happen to launch this instance before you set --vncserver_listen to 0.0.0.0? If so, you may try to launch another instance and see if vnc is working properly.Just for the record, --vncserver_listen is generally set to the hosts management ip, rather than the public ip or 0.0.0.0, for security reasons.

Are you sure your libvirtd will start /usr/bin/kvm with libvirtd group?In default, the /usr/bin/kvm is running with libvirt-qemu like user (that depends on how it is built). you can try to check it by running "ps -ef" to see the effective user and group id after starting a VM in your way.-openstack-bounces+gongysh=cn.ibm@lists.launchpad.net wrote: -To: Diego Parrilla Santamaría diego.parrilla.santama...@gmail.comFrom: "Vaze, Mandar" mandar.v...@nttdata.comSent by: openstack-bounces+gongysh=cn.ibm@lists.launchpad.netDate: 04/04/2012 06:43PMCc: "openstack@lists.launchpad.net" openstack@lists.launchpad.netSubject: Re: [Openstack] Instance fails to spawn when instance_path is	nfs	mountedØ
Check if not only root can write on the nfs share (specially libvirt user).It doesn’t look like permissions issue to me. Just to be doubly sure, I “touched” a file, in that folder, edited and deleted the
 file. All operations worked w/o error.
As I have listed below, several files got created with correct user/group settings. In fact, “instance-0005” folder itself
 was created with correct permissions.

I cannot find a complete example that shows the "endpoint-create" for all of the relevant services. (DevStack usesthe template file backend, not the database backend, so I can't use it for an example).In particular, do we have to create a separate endpoint for each tenant? Are endpointTemplates still around or are they gone now?

I've written a guide on how to install OpenStack Essex on Ubuntu 12.04.
It covers the installation and configuration of Keystone, Glance, Nova

much OpenStack experience so far should be able to get the virtualization
environment up and running in a short period of time.
The full document is available from here:

All feedback and comments are much appreciated -- thanks in advance!
