2016-01-29 10:12:06 -0600 asked a question Configuring Network and Nova

I am very new to networking and cloud. I some have managed to install Openstack with Nova networking. I can access the dashboard. Now I need to create a network. After clicking on the networks tab. It prompts me to select whether it is Admin State or Shared or External Network. I have no idea what to select. Next it asks me to enter the subnet. I have no idea what it is. I have installed single node Openstack. It's IP is 192.168.1.36. What should be the subnet range? I have read somewhere that we need to create public and private networks and we need to create a router to connect them. But I don't know what should be the IP ranges. Another problem is I need to create a floating ip pool, so that the instances can be accessed from internet. But again I don't know what should be the range. Should it be the same as the network that is created? or am I going wrong anywhere? Please help me.

2016-01-25 04:59:21 -0600 asked a question Creating applications on Openstack

I have installed Openstack in Ubuntu vm which runs on windows operating system. I can access the horizon and create image instances. Now I want to create an application using Openstack. How to do that? Where to start? Can anyone help?

2016-01-25 04:57:00 -0600 asked a question accessing openstack horizon through client

I have two systems which are connected through LAN. Both are connected to internet. Both run windows operating system. Using Oracle Virtual Box, I have created Ubuntu vms and installed Openstack from here. I have installed Openstack on both the systems. Now the problem is I need to access the horizon of one system through another. As I have mentioned both are connected through LAN. One system has both eth0 and eth1(dhcp and static, respectively). I have installed Openstack on static IP in one system and dhcp IP on another. Now I want to access the horizon of the server which runs on static IP. When I try I get error message. As I am new to Openstack I don't know where I have gone wrong. Could you please help?

2015-12-05 03:30:41 -0600 asked a question error installing rdo kilo with proxy

I have installed Centos 7 in virtual box. The laptop used proxy to connect to internet. After installing Centos, I have added the "http_proxy","https_proxy" and "no_proxy" environment variables. Every thing works fine, I can access internet through browser, and all commands through command line like "yum", "wget" are also working. But when I install packstack and run "Packstack --allinone" command, I ended up with the following error,

Pre installing Puppet and discovering hosts' details[ ERROR ]

ERROR : Failed to run remote script, stdout: Loaded plugins: fastestmirror, langpacks
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was

One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:

 1. Contact the upstream for the repository and get them to fix the problem.

 2. Reconfigure the baseurl/etc. for the repository, to point to a working
    upstream. This is most often useful if you are using a newer
    distribution release than is supported by the repository (and the
    packages for the previous distribution release still work).

 3. Disable the repository, so yum won't use it by default. Yum will then
    just ignore the repository until you permanently enable it again or use
    --enablerepo for temporary usage:

        yum-config-manager --disable <repoid>

 4. Configure the failing repository to be skipped, if it is unavailable.
    Note that yum will try to contact the repo. when it runs most commands,
    so will have to try and fail each time (and thus. yum will be be much
    slower). If it is a very temporary problem though, this is often a nice
    compromise:

        yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

Cannot find a valid baseurl for repo: base/7/x86_64

I have tried putting proxy variable in yum.conf file, if I do that I can't even run yum command. Please help me with this. Thank you.

2015-12-02 08:48:07 -0600 asked a question Horizon VNC not working

I have installed openstack using RDO on centos vm. I created a cirros instance and assigned a floating ip to it. When clicked on console menu, I am getting an error message "The server closed the connection without sending any data". I have added port forwarding rules 80 and 6080. Please help me with this. I have tried googling but it didn't help. Thank you.

While assigning floating ips its says no ports available. Is that a problem? and also in my network topology I can see only public network (a globe) in the centre unlike the ones I saw in some tutorials which had various topologies. Do I need to do anything extra like setting up a network?

@Prateek K. Thank you for your reply. I am a beginner in openstack and cloud environment. I didn't understand your answer properly. But anyway I have installed all the components on a single machine. Can I use iptables command in my machine?

One more thing is that the dashboard is too slow. It is taking minutes to load next page. I have searched for it and found that tokens should be removed from the database. I have done it but still no use. Any idea?

2015-11-29 22:15:17 -0600 commented answer Accessing instances from another computer

I am currently outside @Bipin. Thank you for your reply. Can those instances be accessed from anywhere in the world, like if the other computer is connected to some other network?

2015-11-29 21:55:32 -0600 commented answer Accessing instances from another computer

I have done it. But when I try to access it I am getting request timed out error. I am trying to ping it from command prompt. Do I need to do anything extra.

I have installed openstack liberty on centos vm using RDO. I have created a cirros instance. If i associate a floating ip to that instance, can i access it from another system which is connected to internet through another network?

2015-11-28 15:07:59 -0600 marked best answer starting with openstack

hello, I am completely new to openstack. I am having a few doubts regarding openstack. Googling about it didn't help me. I am doing a project on implementing a private cloud using Openstack. My final goal is that I should be able to run openstack on two systems, one acting as a server and the other as a client. The client should be able to access the instances which are created in the other system's horizon. I have managed to install openstack on both the systems. I don't understand what are controller and compute nodes. Should both these nodes be installed on the same system?

  • how can access the instances created on one system from the other? (Both are connected using ethernet cable)
  • is the LAN connection necessary or is there some way to access the instances from anywhere?

    Please excuse me if I sound dumb. Please kindly help me guys.

@sanghai. Yes I have installed devstack on both the systems. My doubt is should we connect both of them using LAN cable or is there a way to access that IP anywere? and also could you please tell me how to assign floating IPs and how to access them through another system?

@Antonio G. I haven't tried assigning floating IPs. I didn't get your first part. I haven't used any networking. I have just run ./stack.sh on both systems. I have just connected them using ethernet cable. Could you please explain how to do that? I am very new to openstack and cloud.
