VyOS on Hyper-V

Hyper-V is a Microsoft technology for virtualizing operating systems and hardware components. Hyper-V lets you create virtual hard drives, virtual switches and a number of other virtual devices all of which can be attached to virtual machines. This is a popular hypervisor that can be further enhanced with the networking capabilities brought by the open source VyOS.

Hyper-V Virtual Switch comes with programmatically managed and extensible capabilities that allow you to connect virtual machines to routers and other devices on virtual and physical networks.

VyOS is a virtual router that allows you to have a separate network for all of your Hyper-V virtual machines and route their traffic to the internet through your private networks. With a virtual router, you can configure an unlimited number of routed subnetworks for your Hyper-V virtual environment with as few as two virtual network adapters and extensive use of VLANs.

VyOS includes drivers and other modules required for ideal performance and dynamic hardware reconfiguration in Hyper-V environments. In addition, VyOS does not have per-instance and per-core licensing, meaning you can scale your installations without having to worry about additional investments.


Automation friendly
Automation Friendly

You can automate the deployment with your DevOps tools of choice, or you can deploy the image manually through the VyOS CLI. Afterwards, you can upgrade it to the latest version of VyOS and migrate the config to a freshly updated instance. You won’t need to reinstall and configure each appliance from scratch

Advanced Routing & Networking
Advanced Routing & Networking

VyOS offers standard network services such as DHCP server and relay, DNS forwarding, and web proxy. QoS and policy-based routing allow for the optimal handling of the traffic flows. Support of advanced firewall and NAT.

Reliable Connection
Reliable Connection

Establish a controlled access to your private and public networks as well as the internet in general. Hyper-V provides replication and backup functionality for virtual machines. Increase the availability and reliability of routing paths via automatic router redundancy on an IP subnetwork with VRRP.

Configurable Environment

Hyper-V allows configuring individual parts of a virtual machine like a physical computer, such as memory, processor, storage and networking in different ways in order to meet various needs. VyOS may be adapted to any network topology and required extent functionality.

What Our Customers Say

As an ISP, one of our most important use cases is to be able to run full BGP tables without any issues. We have been using VyOS for this for years now and it has worked absolutely flawlessly. I don’t think we’ve ever had an issue with this, in fact.

We also use VyOS to host a couple of hundred server-networks and VyOS handles this with ease, even with some of our networks having crazy amounts of access-rules on them and often having consistently high throughput and burst rates.

Whenever we do experience issues or we simply have theoretical questions, it never feels like the support team is far away. We usually receive very quick and concise answers to our inquiries. It’s a very nice feeling to know that everyone that’s working on the VyOS project seem to be experts at it, it does a lot for our confidence in running VyOS as much as we do.

Max Sörensen

I reached out to the Vyos team with an issue regarding my subscription and it was promptly resolved.

I have been using vyos for the past 6 maybe 7 years, came from pfsense and never looked back.

The most important features for me:

  • Ease of use
  • I can configure everything from the command line and have made small modifications as time has gone by. I keep a script with the full command set applicable to my firewall.
  • QoS
  • Setting up fq-codel is extremely intuitive and works flawlessly. I never had this kind of QoS with other solutions.
  • I do miss a web interface to display stats and such, but I can live without it for the time being.

I have nothing but good things to say about the VyOS Support Engineers. I think Dmitriy has owned our last 2 ticket, and the rest of the Support Team have all helped out. Taras, Yuriy, Jose, (and I hope I didn’t miss anyone) are quick to contribute and answer any questions I have. I believe it was Taras that even updated the VyOS/VMware doc to clarify a few things that I needed help understanding.

My boss just recently purchased a VyOS Subscription, or license, because we were experiencing a couple bizarre issues during our VyOS refresh of 30+ routers. We were struggling due to a single “show-stopper” issue, month after month, and not able to proceed with the rest of the refresh project. My boss, Daya Rajaratnam, decided we needed to get Commercial Support and open proper tickets and also to show our support of the VyOS Team.

Just hours after our Support PO went thru, I opened a ticket. I gave it a relatively low priority so I would know what to expect with future tickets. Its was great to see a response from an Engineer in just a couple hours. Fast forward a few days and the root cause was identified, I had a simple workaround in place and working in production(and had learned a lot from other Support Engineers that had contributed). What a HUGE load off my back to have that issue resolved with a reliable fix. 5 Stars for service, knowledge, and going above and beyond. (Hell, can I give them 10 stars?).

4 days later I opened a second ticket about an unrelated VTI issue that had also been plaguing us for many months. The experience was equally impressive and I again had a simple and reliable workaround.

Working with this group was a real pleasure.

I use Vyos from the beginning and his predecessor Vyatta. I like platform because has own style of architecture and similar cli like cisco and juniper.

I use platform to make migration from site to site or hybrid migration with Cloud.

I’d like that platform has all ipv6 attribute and use it very much.

Pavlin Dulev

VyOS is the backbone of our company network since the early Vyatta 6.x days. It scales to meet your needs – from 256MB Alix-Board Low-Power Box for small branch offices to multi-processor rackmounted/virtualized network appliance – and is extremely easy to integrate with other systems like monitoring and configuration management. The excellent support from Sentrium turns it into a truely complete product that meets all our requirements.

I’m happy to recommend VyOS/Sentrium. We first began using VyOS several years ago; we maintain a VPN from cellular vendor network to our infrastructure. Since moving our infrastructure permanently to AWS, we decided to sign up for Sentrium’s professional product and service.

I recently ran into a peculiar issue with the IPSEC VPN after a version upgrade – Sentrium staff worked with me to resolve it, and were very prompt in providing information and resolution. We are running two instances, a primary and a backup, and both are working splendidly, with seamless failover.

Paul Theodoropoulos

Thank you for the prompt support. It is great to know that not only the product is a perfect fit for our needs, but also knowing that there is a professional support team we can rely on.

We use VYOS to connect distributed POPs to our data centers and provide secure Internet connectivity to the POPs.

Dan Shechter

I think you have a great product. Actually I like promoting your product to other customers and using it for demo purposes.

You are one of a kind today to support almost all network protocols.
