Dashboard Console not working - opesntack on Oracle Linux 6.6

I have installed openstack using the instructions at http://www.oracle.com/technetwork/server-storage/openstack/linux/documentation/oracle-openstack-user-guide-2296176.pdf
I have a Oracle Linux 6.6 as the controller and two nodes of Oracle VM 3.3.2 as compute nodes. I managed to get an instance up and running but not sure how to connect to those instances. When I navigate to the console tab of the instance vnc connects successfully the be screen is blank and I think its not accepting any keyboard inputs as well.
How do I get the console to work from the dashboard (or connect via a vnc viewer)? Alternately I have used DHCP in the instance and know the private IP of the instance (192.168.1.100), how do I ssh to the instance?

Hi Amish,
I saw your comment in other thread and I'll try to answer your questions in the best way I can - but this is huge topic. Please keep in mind that I'm also newbie in this area too and I've encountered many problems getting basic OpenStack installation working, like you. Some of them are still not solved for me either. I also did not get any help here
Networking in OpenStack is IMO difficult to understand, especially for people like me who are accustom with traditional approach. So this is how I understand it now:
Networking can be purely software driven and in this case it is carried out by openvswitch (http://openvswitch.org - better get accustom with it if you are not yet). Simple linux bridge - utilized by Oracle VM - is not used by OpenStack. Also there can be hardware plugins which can move some of network features to hardware - but I have no experience in this area.
There are two types of networks you can create in OpenStack: provider and tenant one:
Provider networks (also called flat networks) are equivalent of what you set in Oracle VM Manager and in typical (old fashioned) IT world. These are networks which in OpenStack are defined by cloud administrator (You) and bound to existing physical network which are already set by network administrator. For example you have couple of ports on your servers connected to LAN switches, some of them are in access mode some are trunks of specific VLANs. Also routers and other network services are managed outside of your cloud.
You need to define these networks in OpenStack before any user can connect their VMs to them. The most important part is that can do this from the GUI .
On the other hand there are so called: tenant networks. These are networks which are under cloud user administration. These are like cloud private networks (if you know Ops Center or Exalogic there is similar notion there) - which are created on-demand by your users. You as cloud administrator only create some limits (quotas) regarding how many such networks can be created by user. But obviously you - as cloud administrator - also need to define mechanisms which allow such networks be created on demand. This also has to be done from command line by editing some files - before users can create tenant networks.
The mechanism I'm talking about can be: VLAN, VxLAN, GRE.
First one is the only one currently supported by Oracle and it is quite simple: you, in cooperation with your network administrator reserve range (or set) of traditional VLANs and configure them on network switches where your servers are connected (I mean server ports which you dedicate for tenant networks - not all because you need other network for management, etc). Then you define this set in some OpenStack files to let it manage them on its own. For example: you have got 20 VLANs from network department for exclusive use for your cloud. Nobody knows what each VLAN will be used for yet. This will be allocated by cloud users on-demand. Openstack will just allocate VLAN upon user request and will not allow other users to create their private networks on the same VLAN.
Better approach is to use VxLAN which is tunneling mechanism. You don't need pool of VLANs in this case but you just set tunneling rules and then OpenStack creates private networks using secure tunnels over L3 network which you define first. VxLAN is standard, you can read about it and it is used by OpenStack for Solaris. Unfortunately this did not work for me and Release Notes from Oracle OpenStack for Linux says that it is not supported yet.
There is also GRE - which is also tunneling and is similar to VxLAN - but it did not work for me either.
Where it is all configured? Basic setup is created by packstack using CONFIG_NEUTRON_OVS_* variables. However I used packstack only for installation and then I modified configuration files on all nodes. The most important file where configuration is kept is: /etc/neutron/plugin.ini. In this files you set framework on which provider and tenant networks are build. The most important section is [OVS], for example:
[OVS]
enant_network_type=vlan
enable_tunneling=false
integration_bridge=br-int
bridge_mappings=physnet1:br-eth3
network_vlan_ranges=physnet1:2032:2032,physnet1:3010:3020
This example is from compute node. It says: I have one physical network: physnet1 which is supported by virtual switch called br-eth3. You need to create this virtual switch on your own! OpenStack networking deamons (Neutron) do not create virtual switches - they only reconfigure them if needed. Physical network is just name which you can use later on if you setup provider network.
Also, in the example you tell OpenStack that you have 11 VLANs available on physnet1 network. Similar configuration has to be done on controller node (but it is only because in simple topology your controller is also network node)
Then I dedicated first VLAN: 2032 for provider network. This was accomplished by command issued on controller node.
# neutron net-create --router:external=true --provider:network_type=vlan  --provider:physical_network=physnet1 --provider:segmentation_id=2032 labnet
From that moment this network (called "labnet") should appear in the GUI and you can connect VMs to it. Users might also do this if you mark it as "shared".
Also users should be able to create their private networks and this will allocate VLANs from 3010 to 3020 - so there can be only 10 private networks created totally in your cloud now.
Of course this is example and you can build completely different setup. You can use different ports for provider networks and for tenants one. You do not need VLANs for provider networks and theoretically for tenant too - but you would have to have plenty of ports for this. If you manage to get VxLAN working - then please share your experience here.
I strongly recommend reading following information sources (Oracle does  not provide this details in their documentation):
OpenStack Docs: Current
https://developer.rackspace.com/blog/neutron-networking-the-building-blocks-of-an-openstack-cloud/  there are more blog entries (followups) on this topic - look for them using keyword "neutron"
https://www.rdoproject.org/forum/discussion/875/does-rdo-support-flat-network-type-/p1
As for blank VM console:
I've also had this problem when I used Cirros VM images. However when I imported the template I use on my Oracle VM - then console was working correctly. I think this is more connected with VM configuration then OpenStack. AFAIK you can connect to console directly using vnc client - at least you can configure Nova in that way that it allows external VNC connections.

    Dashboard widgets not working. I trash the dashboard .plist and redo all widgets then after a restart. Widget not working again.

    Yes hello,
    My widgets are not working as well, i looked on forms and it seams that the 10.5 update fix there problems. I also did an archive and install from 10.4... One of the major reasons i purchased the upgrade was to use widgets to clip parts of safari, i'am totaly bummed because all forums i find end with the question un answered. i'am a little bummed becuase there are a couple of things that worked with 10.4 that are not working in 10.5 (like some meg moives not playing.
    i do not wish to create a new account because i do not want to reinstall all my software, photoshop, final cut, dvd studio pro.. etc.
    i hope to find the fix some how.
    I have opened up the console application and when i select widgets load or delete them i see no activity in the console. I'am not familiar with the console app. or command lines.
    is there any more info on this matter? is there any support from apple?
    Thankyou

    Why is your "requirement" to install in graphical mode?  Once you are past the installation itself, the only thing that buys you is that your server will have been configured to boot up to runlevel 5, running a graphical desktop (gnome or kde, I forget which).  And what does THAT buy you on a server?
    I do not run ANY of my Linux servers "in graphical mode" -- running a graphical desktop.  Nor did I run a graphical desktop when I had Solaris, AIX, or HP-UX servers.

  • Safari, dashboard & help not working after 10.4.9

    I have loved my iBook since day 1, until 10.4.9. This is my first Apple computer and I was very close to being a convert. I updated through sys prefs to 10.4.9 and now: Safari opens for a split second then closes with kernel errors (or I least I assume from the crash log), no more widgets and dashboard does not work and help files do not work. What gives? I tried downloading the combo update but it was a .exe file. Forgive my lack of tech know how, I know some, enough to get me in trouble evidently. Any help would be greatly appreciated. I have tried booting into safe mode, Safari does the same thing, I have tried repairing permissions in safe mode and in regular mode as admin, nada. HELP!

    I originally updated through sys pref and just let it go. One day later things stopped working. Repairing permissions etc did nothing. Applied the combo update, verified the disk before hand, repaired permissions after the update and reboot, now things are back to normal as far as I can tell, better even in some areas. Hope this can help others with similar problems.

  • Overdrive Media console not working with iTunes when transferring audio books.  Any suggestions?

    Overdrive Media console not working with iTunes when transferring audiobooks.  Some parts don't transfer.

    Robin, I have the 4S too. Here's wha I've been doing. Well, I am downloading wma books, but it is super time consuming and annoying. First, shut off genius in your preferences in iTunes. Also change to spoken podcast for speed. Then, you start to transfer from Overdrive. It will create a playlist with your book title. Open up books though because you need to keep an eye on it. It may download like three parts and then you may have a grey one. When you get the grey, cancel the transfer, delete the greyed part, exit iTunes, re-enter iTunes, and then try to download the remaining book parts. I usually have to re-enter iTunes three or four different times during a book. When your book is downloaded, all black and none grey, open up the playlist folder and double check that all parts made it in there. If not, carry them from the books folder to the playlist and then move it into numerical order.
    Re non bookmarking problem. I now have a new habit of checking what part I am on before i shut off my phone or switch to another book. It does save where you were, it just doesn't show you. For instance, if I start part three and then play music, and then go back to the book playlist, it will appear as if we are back to the beginning, but if I go to part three, it will start up from where I was. So, just start checking and then it is easy. I am flabbergasted that no other proper solution has been offered by Overdrive. This has been a problem since October. I also wish they would acknowledge the problem on their website as well as post what version number of update they have. I have 3.2.1.0 and think that's current. Does anyone have newer than this. Good luck, and happy commuting!
    An easy, quick workaround is to plug external speakers into your laptop and take it with you in the car. A bit unwieldy, but I can't commute without books.

  • Dashboard does not work today.

    I have upgraded both my MacBook Air and my Mac Mini to OS 10.9.2.   The Air works just as it did in 10.9.1.  Dashboard works on the Air.   But Dashboard on the Mini does not operate.  I click on the Dashboard icon in the Dock.  Nothing happens.  I click and hold on the Dashboard icon.  The pop-up menu appears.  In that menu I click "Show Dashboard."  No response.  I click "Dashboard Preferences," and I get the Mission Control Preference.  Here is how that appears:
    I do not see anything here that would disable Dashboard.  
    Does anyone have any idea as to why Dashboard does not work in 10.9.2?  
    TIA

    Hi Richard,
    Thanks for visiting Apple Support Communities.
    If Dashboard does not launch on your Mac Mini, you may want to see if the behavior occurs in a new user account. This article is a good guide for troubleshooting:

    The console starts and all is well with the world.
    This is obviously not how one would want to start a console by downloading the .jnlp file and running it on the command line so I am now going to remove the /home/gordon/.icedtea/cache/http/* and see what happens.
    First, let me say that nothing happened. It did not work. I did confirm that it creates the directory structure again /home/gordon/.icedtea/cache/http/192.168.4.16/ovm/rasproxy/ but there is only one file in the directory.

    If I save that ovm_rasproxy-ws.jnlp file instead of opening it and copy it to the /home/gordon/.icedtea/cache/http/192.168.4.16/ovm/rasproxy/ directory the console will now start successfully with one minor drawback - it will only launch that one VM based on the .jnlp file that I downloaded.
    Help?

    The platform is one for development installer on RedHat 5 OS.
    Any ideea ?

    Man Christian!
    1000 Thanks for your tip. I run into same issue on W2K3 with 10.1.3.4 MLR#4 (so far last MR allowed for AIA apps).
    I had the orabepl.ear file of the size as was mentioned earlier: 2.530.260 in the bpel\system and other one on the j2ee\ocj4_soa\applications folder.
    Copying did not help.
    I had to perform following steps from the <MLR#4>/custom/scripts/post.bat file which takes the file from the bpel\system,
    ADDS some another .jars in it and ONLY THEN move it to the j2ee\...\applications folder:
    copy %ORACLE_HOME%\bpel\system\j2ee\orabpel.ear %ORACLE_HOME%\bpel\system\services\lib\orabpel.ear
    copy %ORACLE_HOME%\bpel\system\j2ee\ejb\oc4j_ejb_services.jar %ORACLE_HOME%\bpel\system\services\lib\ejb_services.jar
    copy %ORACLE_HOME%\bpel\system\j2ee\ejb\ejb_ob_engine_oc4j.jar %ORACLE_HOME%\bpel\system\services\lib\ejb_ob_engine.jar
    cd %ORACLE_HOME%\bpel\system\services\lib
    %ORACLE_HOME%\jdk\bin\jar -uvf orabpel.ear ejb_services.jar ejb_ob_engine.jar
    After doing manually these steps the orabpel.ear in j2ee\...\applications has got the size: 2.798.840 which was bigger as right after patch application.
    Then I deleted the orabpel folder from the j2ee\...\aplication-deployments
    started the j2ee containe (it was named: oc4_soa ) and the BPEL Console started live well as before in 10.1.3.3
    As I did verify from other files The rest of steps from the post.bat file seems did well, only this part was not executed.
    With Best Regards,
    Alexey

  • Em console not works

    hallo,
    I work with a oracle database where there are install 2 instance. The operative system is win 2003 32 bit.
    Now I would like to work with em console, but the window service doesn'start.
    I try to open a dos shell and type emctl.
    This utility, write on the screen that the windows environment variable ORACLE_SID is not set.
    Now I think that there are 2 oracle sid: ORCL and GIS.
    (I open the file listen.ora on the server where oracle is installed and I read this string there.)
    Is it correct if I set the windows variable ORACLE_SID to ORCL?
    The second oracle instance can go in a fail state for this setting ?
    thanks' in advance anyone answers.

    This isn't about Grid Control. The OP is interested in using EM with each of the database instances he has. This is perfectly doable without Gid Control.

    I pointed out your obvious lack of courtesy and, the fact that your answer is inaccurate and besides the point made by the OP. Your reply still lacks in courtesy and, still offers no facts that may be useful to the OP.
    Your answer is 100 percent incorrect, because you don't know the difference between the Grid Control Architecture and Database Control Architecture.
    The answer is correct. The OP can manage both instances individually using EM and without Grid Control.

    Doing so, you again start accusing me of posting inaccurate answers, where it is quite clear you are trying to divert the attention from your incorrect answers.
    Your post is inaccurate and I pointed it out for the benefit of the OP. It would be my pleasure to divert your attention to another thread where you would hopefully make a more valuable contribution than the one you made in this one.

    People like you should go for dictator, not for DBA.
    I hope that someone in charge of these forums reads this thread. I suspect their opinion will not coincide with yours.
    As I mentioned in my first post, there is a thread in this forum - not that old - that gives most of the necessary information to manage more than one database instance using EM. You really should consider reading it.
    Lastly,
    The forums are meant for professional people to help each other. They are not here for you to flame me or others. If you find that something I said is unclear or, even mistaken, you could simply and, politely point out what you think may be the problem and, it would be my pleasure to clarify any statements I've made.
    For the benefit of the OP, I reiterate,
    My first post is completely correct. If any statements need to be clarified, it will be my pleasure to clarify or expand them as necessary.
