Sizing your Virtual Machine
Your Vx license limits the amount of supported CPU cores you can use for your virtual Barracuda NG Vx. Storage and RAM can be sized to fit your needs and are not limited by the license of the Barracuda NG Vx.
|Vx Virtual System||Number of Licensed Cores||Minimum Storage [GB]||Minimum Memory [GB]|
NG Firewall VF25, VF50, VF100, VF250, VF500, VF1000
|NG Firewall VF2000||4||80||2|
|NG Firewall VF4000||8||80||2|
|NG Firewall VF8000||16||80||2|
|NG Control Center VC400||No core limitation||125||2|
|NG Control Center VC610, VC820||No core limitation||250||2|
- Supported Versions – VMware ESX(i) version 3.5 or above
- Image Format – *.ova
- Max Number of virtual network adapters – 10
To deploy the Barracuda NG Vx on your VMware hypervisor, download the NG Firewall or NG Control Center image from the Barracuda Networks Download Portal. If you want to deploy using the standard configuration, use the OVA image. If you want a custom configuration, download the generic Barracuda NG Vx ISO image and Barracuda NG Install to carry out the deployment.
To deploy a Barracuda NG Vx on a VMware ESXi server, see How to Deploy a Barracuda NG Vx OVA Image on VMware Hypervisors or How to Deploy a Barracuda NG Vx using Barracuda NG Install on a VMware Hypervisor.
- Supported Versions – XenServer and Citirix XenServer 6.0 or above
- Image Format – *.hvm.xva (fully virtualized) or *.pv.xva (paravirtualized)
- Max Number of virtual network adapters – 8
Xen images come in a fully virtualized or paravirtualized version. If your XenServer supports paravirtualization, it is recommended to use the paravirtualized image for best networking performance. Download images to match your XenServer from the Barracuda Networks Download Portal.
To deploy a Barracuda NG Vx on a XenServer, see How to Deploy the Barracuda NG Vx on a Citrix XenServer.
- Supported Versions – KVM 5.4.2 and above
- Image Format – *.kvm.zip
- Max Number of Virtual Network Adapters – up to 28 (depending on the configuration and number of devices in the VM configuration)
KVM uses a different approach for attaching devices to the virtual machine. It uses an emulated PCI controller with 32 slots. 5 slots are permanently occupied by necessary system components and disk controller. The remaining 27 slots can be freely assigned to other devices, including networks adapters. The KVM image for the Barracuda NG Vx uses the virtio paravirtualized network adapters for best performance.

- Virtual Disk Format – *.vhd
- Max Number of Virtual Network Adapters – up to 8 network adapters + up to 4 additional "legacy network adapters"
Barracuda Networks offers a Virtual Disk you can use to install the Hyper-V version of the Barracuda NG Firewall. Download the virtual disk from the Virtual Appliance Download Page.

When choosing which hypervisor to use, Barracuda Networks recommends using VMware ESXi hypervisors for network-intensive tasks, and KVM hypervisors for units with high disk load.
