VyOS on KVM
KVM is a full virtualization solution.
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. This flexibility helps you 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
Responsiveness and Productivity
Improved I.T. responsiveness and productivity. Provisioning virtual machines can be automated and made available in minutes.
Efficient Use of Computer Resources
The consolidation of virtual machines onto fewer physical machines results in less physical resources and therefore better efficiency.
The saving comes in the form of reduced energy bills as a result of lower cooling and power requirements.
Features and use cases
VyOS is an open-source network operating system based on Debian GNU/Linux that provides software-based network routing, firewall, and VPN functionality. In version 1.2., VyOS switched its routing engine to FRRouting, which makes it an ideal and cost-effective solution for large enterprises, SMBs, network service providers, system integrators, private cloud providers, advanced users and home labs.
As a virtual router, VyOS allows you to have a separate network for all of your KVM virtual machines and route its traffic through your 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.
To ensure your the continuity of your business, we offer enterprise support and services provided by a team of certified network engineers. Documentation with detailed explanations covering all software features is available online 24 / 7.
VyOS includes drivers and other modules required for the best performance and dynamic hardware reconfiguration in KVM environments. In addition, VyOS doesn’t need per-instance and per-core licensing, meaning you can scale your installations without worrying about additional charges.
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.
VyOS supports the Kernel-Based Virtual Machine (KVM) hypervisor on Linux by providing a prebuilt Linux KVM image with a number of Linux KVM-specific modifications and optimizations.
KVM and VyOS help to deliver a perfect virtualization solution.
Here are the main benefits of the solution:
Fully Open-Source Highly Customizable Operating System.
Advanced Routing and Networking services: DHCP server and relay, DNS forwarding, and Web Proxy.
QoS and policy-based routing allow ensuring optimal handling of the traffic flows. Support of advanced firewall and NAT.
Reliable Connection by establishing controlled access to your private and public networks.
Increased availability and reliability of routing paths via automatic routers redundancy on an IP subnetwork by applying the VRRP.
Configurable Environment by flexible adaptation to any network topology and required extent functionality.
