Revision as of 17:30, 1 August 2019

Requirements

Minimal Cloud requirements:

• 64 bits infrastructures only
• Virtio NIC interface
• qemu-kvm CPU exposed as 'host' or minimally 'core2duo'
• One Ethernet adapter for management
• One or more Ethernet adapter(s) for data

** The CPU number is based on Intel R630 with Xeon E5-2643. Double the CPUs number if yours are from a earlier generations.

More details on HW/CPU/NIC requirements can be found here: Requirements Matrix

For better performance (see optimization section)

• SR-IOV or MacVTap compatible NICs
• Overcommit set to 1:1
• No CPU (including hyperthreading) shared between infrastructure and compute section
• Dedicated memory allocation to VM

Getting the Image

Please go to our FreeSBC Download site to get a copy of the latest SBC Image.

Installation on OpenStack cloud

SBC OpenStack Minimal Flavor

In OpenStack, a flavor defines the compute, memory, and storage capacity of a virtual server, also known as an instance. If you do not have a flavor that meets the listed minimal requirements, you will have to create a new one.

Creating a Flavor

1. Log in to the Dashboard and select the admin project from the drop-down list.
2. In the Admin tab, open the Compute tab and click the Flavors category.
3. Click Create Flavor.
4. In the Create Flavor window, enter or select the parameters for the flavor in the Flavor Information tab.
   • Name : TelcoBridges SBC Flavor
   • VCPUs : 4
   • RAM (MB) : 8192
   • Root Disk (GB) : 40
   • Other fields are left to their default value
     
5. In the Flavor Access tab, you can control access to the flavor by moving projects from the All Projects column to the Selected Projects column.
   Only projects in the Selected Projects column can use the flavor. If there are no projects in the right column, all projects can use the flavor.
6. Click Create Flavor.

TBSC OpenStack Image

A virtual machine image is a single file that contains a virtual disk that has a bootable operating system installed on it. Images are used to create virtual machine instances within the cloud.

You will need to upload the latest SBC image into your OpenStack before you can launch a virtual machine instance running the SBC software.

Upload an Image

Follow this procedure to upload an image to a project:

1. Log in to the dashboard.
2. Select the appropriate project from the drop down menu at the top left.
3. On the Project tab, open the Compute tab and click Images category.
4. Click Create Image.
5. The Create An Image dialog box appears.
6. Enter the following values:
   • Image Name : TelcoBridges SBC xx.yy.zz (Where xxx.yy.zz is changed to the version number of the FreeSBC image)
   • Image Description: TelcoBridges SBC version xx.yy.zz
   • Image Source : .qcow2 file. Must not be compressed (tar.gz).
   • Image File : Browse for the image file on your file system and add it.
   • Format: QCOW2
   • Architecture: x86_64
   • Minimum Disk (GB) : 20
   • Minimum RAM (MB): 8192
   • Visibility : The access permission for the image. Public or Private, depending on your needs.
   • Protected: Select this check box to ensure that only users with permissions can delete the image. Yes or No.
     
7. Image Metadata : Leave empty.
8. Click Create Image.
   The image is queued to be uploaded. It might take some time before the status changes from Queued to Active.

SBC OpenStack Instance

Instances are virtual machines that run inside OpenStack's cloud. You will need to launch a new instance from the SBC Image created in the #Upload an Image section

Launching an instance

1. Log in to the dashboard.
2. Select the appropriate project from the drop down menu at the top left.
3. On the Project tab, open the Compute tab and click Instances category.
4. The dashboard shows the instances with its name, its private and floating IP addresses, size, status, task, power state, and so on.
5. Click Launch Instance.
6. In the Launch Instance dialog box, specify the following values:
   1. Details tab
      • Instance Name : Assign a name to the virtual machine. For example: TelcoBridges SBC.
      • Availability Zone : By default, this value is set to the availability zone given by the cloud provider (for example, us-west or apac-south). For some cases, it could be nova.
      • Count : 1
        
   2. Source tab
      • Instance Boot Source : Boot from image.
      • Create new Volume : No
      • Select Image Name : Select TelcoBridges SBC xx.yy.zz as created in #Upload an Image section.
        
   3. Flavor tab
      • Flavor : Select TelcoBridges SBC Flavor as created in #Creating a Flavor section.
        
   4. Networks tab
      • Selected Networks: If you are installing a standalone SBC, the SBC will need access to WAN and MGMT networks. For transcoding, or HA pair installation, the SBC will also need access to CTRL0, CTRL1, and TRANS0 networks. Please refer to FreeSBC-SW:Networking for details on network requirements. For ProSBC Transcoding and associated network setup please also see ProSBC:Transcoding and Network Setup. Important: For optimal performance, it is recommended to use SR-IOV or MacVTap ports to access LAN and WAN networks, see FreeSBC-SW:Cloud:OpenStack_Optimizations for details.
        
   5. Network Ports tab
      • Ports : For optimal performances, SR-IOV and MacVTap ports should be used to access LAN and WAN networks. If you do choose to use Network Ports to attach to LAN and WAN networks, do not attach to them in Networks Tabs. See FreeSBC-SW:Cloud:OpenStack_Optimizations for details.
        
   6. Security Groups tab
      • Security Groups: Activate the security groups that you want to assign to the instance. Security groups are a kind of cloud firewall that define which incoming network traffic is forwarded to instances. If you have not created any security groups, you can assign only the default security group to the instance. Warning: Make sure the selected security group allows ingress traffic.
        
   7. Key Pair tab
      • Key Pair : SSH access to the SBC with a password is disabled by default on the SBC. You will need to provide your SSH public key here in order to get SSH access into the SBC.
        
7. Click Launch Instance.
   The SBC instance will start in a compute node in your cloud.
   When the instance state is changed to Active, you will be able to connect to the SBC using SSH or a web browser as described in the next section..

Accessing the SBC Console

SBC SSH Access

There is no root password by default, you will need to SSH onto the SBC using SSH private key matching the public provided in the Key Pair tab when Launching the SBC instance. Login using tbcloud as username.

For example, if your SBC management IP is 192.168.178.30:

 > ssh tbcloud@192.168.178.30
   ECDSA key fingerprint is 5d:94:a1:93:0f:a4:7a:5d:41:cc:29:49:79:5a:58:f3.
   Are you sure you want to continue connecting (yes/no)? yes
   Warning: Permanently added '192.168.178.30' (ECDSA) to the list of known hosts.
   
   CentOS-7-x86_64-Minimal-1511/112/190195:197392, Fri  7 Apr 17:41:46 EDT 2017
   [tbcloud@freesbc ~]$

Accessing the SBC Web Portal

1. Open a web browser to the management IP of the SBC, on port 12358. Example if your server address is 192.168.178.30, the URL would be:
   http://192.168.178.30:12358
2. You should get to the SBC Configuration Wizard
   

From here, you can go to Web Portal Initial Configuration Guide to continue the installation, and/or optimize your server to get the maximum out of your server.
