FreeSBC:Cloud:Proxmox Installation

This step-by-step guide helps to install and run FreeSBC KVM image to Proxmox platform. The installation requires root-level access to Proxmox host and can not be completed with web-interface only.

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

Sessions	CPU	RAM	Disk Space	Ethernet ports
Up to 5,000	2	4 Gb	40 Gb	1 Gbps
5,000-20,000	4	8 Gb	60 Gb	4 X 1 Gbps or 1 X 10 Gbps
20,000-50,000	4**	16 Gb	80 Gb	1 X 10 Gbps
Above 50,000	6**	24+ Gb	100 Gb	Multiple 10 Gbps

** 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: RequirementsMatrix

For better performance

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

Getting the Image

Please go to our FreeSBC Download site to get a copy of the latest FreeSBC Image. In the Download Section, while filling the form, choose correct platform "KVM". As a result, you should get file fresbc_kvm.qcow2. Please, mention "Product Key" and keep containing email in a safe place.

Upload Image File to Proxmox cloud

You need an SFTP client to upload FreeSBC image to Proxmox. For example, using WinSCP SFTP Client . All the next step assumed that image file fresbc_kvm.qcow2 resides in the /root directory

Create VM for FreeSBC

Define the amount of CPUs and RAM according to requirements. Follow the VM creation process by dialog tabs as below

1. General: choose VM name and location as usual. This manual uses VM ID 1000 as a reference.
2. OS: check Do not use any media, keep default Linux OS with 4.X/3.X/2.6 Kernel.
   
3. Hard Disk: choose your favorite device type and keep all the rest to default.
   
4. CPU: choose core count. Important: CPU Type must be set to "host".
   
   • In the advanced area parameter "CPU units" may be increased to ensure that CPU resources will be allocated to FreeSBC with priority.
     
5. Memory: Set the memory size
   
6. Network: Set up the interface you will use for management according to your network configuration. Model VirtIO tested, any other may work too.
