This page is about using CCVM as a CMU student. For Computer Club members, see Projects/ccvms/Internal_Use. For information about the OpenStack infastructure, including maintenance and deployment information, see Projects/ccvms/Openstack

The CCVM project aims to provide easy-to-obtain virtual machines to members of the CMU community. It utilizes the OpenStack framework to allow users to start their own instance, access the console, re-install and boot their system remotely through a web interface. The interface is available to everyone in the community authenticating as a CCVM OpenStack user.

Currently the CCVMs project uses running 4 hosts, with 3 hosts dedicated as Compute Nodes. Each of the Compute node is powered by 8 Core Intel(R) Xeon(R) CPU X5470 @ 3.33GHz with 6144 KB cache, and 32GB 667MHz DDR2 FBDIMM Ram.

Organizations can contact operations@club.cc.cmu.edu to request an organization account with a higher instance and performance quota. We make no guarantee for the recovery of data stored on the instances, please periodically backup your instances to a safe location.

If you have any problems, please talk to a member of Computer Club! There will usually be people who can help in IRC

Basic CCVM Tasks

OpenStack is fairly intuitive, but web UI, CLI, and API documentation can be found at: http://docs.openstack.org/user-guide/

You can use CCVM instance for anything, as long as you don't violate the CMU computing policy

Launching an instance if you don't know what to do

Here are a step by step guide on how to launch an instance

1. Goto the Instance page from the sidebar link

2. Click + Launch Instance to bring up the instance configuration dialog, see Figure

3. Make sure that the Availability Zone is cclub-east-1

4. Type your instance name, and make sure it's correct; your VM's hostname will be set to this.
5. Choose your instance flavor. The bars on the right side will show you how close you are to your max quota

6. In the Instance Boot Source menu, choose Boot from image

7. In the Image Name menu, choose Debian 7.6

8. Click on the top Networking * Tab

9. Click the blue + or Drag ccvm-net into the blue zone

10. Click Launch
11. Check the Log tab for that insance, where a root password will be printed out after the boot finishes.
12. Find and click "Console" for this instance
13. Log in with username "root" and the password you saw earlier.

14. Change your password by typing passwd

15. Then, follow Projects/ccvms#Port Forwarding to get access to your VM.

Accessing the Log and Console

The Log and the Console allows you to see the detailed status of your instance and perform remote management.

Only when your instance has reached the Active state will the Log and Console will be available.

You can access the console from clicking the instance name in the instance page, and choosing the Log or Console Tab respectively. Your root password will be printed out to the Log on first boot, you can use this password to login in the Console. Note that this log will only be cleared on reboot, and is readable by other members of the organization. So it is important to change your password using the passwd command

Adding Firewall Exceptions

To allow services such as Web and Game servers on your instance to accept connection, you must add an additional rule to the instance firewall

You'll want to open only the ports that you need on the machines that need it, so here's how:

Suppose we are the user demo and want to open port 7777 for the game Terraria for the vm Host-1-Demo:

1. Click on Access & Security on the sidebar

2. On the page that is titled Security Group click + Create Security Group a popup should open

3. On the popup, type the name demo_terraria. It is important to put your name there to prevent conflicts

4. In the description, type Port 7777 for terraria

5. Click Create Security Group, you'll be directed back to the Security Group page

6. Find demo_terraria in the table and click Edit Rules

7. You'll be directed to a page titled Security Group Rules

8. Click + Add Rule a popup should open

9. You can add the specifics of your firewall exception here (see image)

   • In our case, we choose Custom TCP Rule as we don't see a premade rule from the list. If we wanted to open HTTP port, we could choose that premade rule from the list
     Then we leave Ingress as it is as we need a rule to allow traffic to reach our VM
     We choose Port as we only want to open one port. If we wanted to open a range, we could choose Port Range here
     Enter 7777 in the port as that's the port we want
     Then we leave CIDR selected as it is simpler
     And We leave 0.0.0.0/0 as it is as we want everyone to be able to connect to our server

10. Click Add, You'll be directed back to the Security Group Rules page

11. Verify that the new rule has been added in the table

12. We will now apply this group to a VM. Click Instance on the sidebar

13. Find your host, and in the last column, click More a dropdown should appear

14. Click Edit Security Groups A popup should appear

15. On the left, find your security group and click the blue + button

16. Click Save

Now that you have the security group, you could also apply this group when you create a new instance though the Access & Security tab

Port Forwarding

Unix machines reboot at 4am, Join Computer Club today to get access to unix machines that do not reboot

You can use ssh to port forward your server's port to one of andrew unix's machine. You can then connect to this port from anywhere in the world.

We'll use port 7777 on our vm Host-1-Demo and port 8000 on unix1.andrew.cmu.edu. Note that because Andrew machines are a shared resource, the port you want may not be available. Simply pick a different port, and tell your client to use the alternate port.

Here's a quick diagram of how a packet will travel

(Internet) --> (unix1.andrew.cmu.edu listening on 8000) --> (unix1.andrew.cmu.edu listening on 7777 allowing only unix1) --> (Host-1-Demo listening on 7777)

On your instance's console, type:

   1 ssh -R 7777:localhost:7777 <YourAndrewID>@unix1.andrew.cmu.edu
   2 #<YourAndrewID>@unix1.andrew.cmu.edu password: <Your unix password>
   3 
   4 # On unix1 console, (it can be the one you got from the above step)
   5 
   6 ssh -L 0.0.0.0:8000:localhost:7777 localhost
   7 #<YourAndrewID>@localhost password: <Your unix password>
   8 

Organization related CCVM Tasks

Organizations can perform additional tasks in addition to the basic tasks

Switching to the Organization project

If you are a part of an organization, you can switch over to manage the organization's project.

On the top of the blue section of the sidebar, where it says CURRENT PROJECT <Your name> You will now see a dropdown. By clicking on that dropdown, you'll see the organizations that you belong to, and can can switch to their VM group by clicking the organization name.

Note that every VM in the organization project group can be seen and fully edited by other members of your organization.

Allocating a public IP

The cluster only has 23 Public IP address, so please be considerate when using a Public IP address

On the Instance page, on your instance, you can click More and click Associate Floating IP. In the popup you can click the grey + and then the blue Allocate IP. You'll receive an IP address from our pool, please note this IP address down. Then you can click the blue Associate button.

The new IP should start working right away, and will be displayed on your instance screen after a couple of minutes.

Allocations

Once you've created an CCVM OpenStack account, you'll be given the community level of CPU, RAM, and VM allocation. As we move on with this project, we may be able to increase your allocation as demand increases and we acquire more hardware.

We can also make special allocations for anyone who contact us with a legitimate use case. Please contact operations@club.cc.cmu.edu with your request.
