VyOS on KVM

KVM is a full virtualization solution (able to run unmodified guest OS images) for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of an open-source loadable module for the Linux kernel that provides the core virtualization infrastructure and allows the creation of emulated/virtualized hardware, which can be used to boot virtual machines. KVM is the most popular hypervisor for service providers running the OnApp cloud management platform.

Modern hypervisors typically support hybrid virtualization: hardware-assisted when possible and failover to software-only for older chipsets.
KVM is categorized as a type-2 hypervisor, meaning that it runs within a host operating system and supports only Linux as its host OS.

Its paravirtualization functionality allows the Hypervisor to provide a guest virtual machine access to certain physical hardware including disks, NICs, and Video Adapters. Such flexibility helps you to create the ideal virtual solution for you and your client’s requirements.

Virtualization powers the running of multiple virtual machines, each potentially with a different OS, on a single physical machine. With KVM, you can use the multiple virtual machines running unmodified Linux images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.

The advantages of VMs over physical machines

Improved I.T. responsiveness and productivity. Provisioning virtual machines can be automated and made available in minutes.

More efficient use of computer resources. The consolidation of virtual machines onto fewer physical machines results in less physical resources and therefore better efficiency.

Cost-saving. The saving comes in the form of reduced energy bills as a result of lower cooling and power requirements.

VyOS on KVM

Features and use cases

VyOS is also an open-source network operating system based on Debian GNU/Linux that provides software-based network routing, firewall, and VPN functionality. In its latter version 1.2., VyOS changed routing engine to FRRouting, which makes it an ideal and cost-effective solution for large enterprises, SMB’s, network service providers, system integrators, private cloud providers, advanced users, and for home labs.

VyOS supports the Kernel-Based Virtual Machine (KVM) hypervisor on Linux OS by providing a prebuilt Linux KVM image that runs on the KVM. This image has a number of Linux KVM-specific modifications and optimizations.

As a virtual router, VyOS allows you to have a separate network for all of your KVM virtual machines and route its traffic through the normal private network to the internet. With a virtual router, you are able to configure an unlimited number of routed sub-networks for your KVM virtual environment with as little as two virtual network adapters and extensive use of VLANs.

VyOS includes drivers and other modules required for best performance and dynamic hardware reconfiguration in KVM environments. Also, VyOS doesn’t need per-instance and per-core licensing meaning you can scale your installations without worrying about additional investments.

Being focused on routing, VyOS offers its users access to enterprise-grade functionality such as powerful traffic filtration, flows analysis, HA topologies, IPsec, OpenVPN, and NAT.

To ensure your business continuity we offer enterprise support and services provided by a team of certified network engineers. The availability of documentation with detailed explanations covering all software features is available online 24/7.
