VyOS on XCP-ng

XCP-ng is a high-performance enterprise-level virtualization platform with a vibrant ecosystem, recognized by industry-leading solutions and designed for server, desktop, and application virtualization. Based on Citrix XenServer Hypervisor, XCP-ng is a fully open-source virtualization platform meaning it’s easily usable from the source and provisioned by continuous improvement of the update process to make it more turnkey, allowing you to build a manageable infrastructure with scalable virtual resources.

Being compatible with most x86 servers on the market, XCP-ng has determined its primary goal – to deliver an easy way for the deployment of a VM-based infrastructure using Xen as a hypervisor and the powerful Xen API Project (XAPI) to provide a turnkey, working out-of-the-box solution for enterprise and data center platforms requiring virtualization.

With XCP-ng’s main product, called Xen Orchestra, a web-based GUI and designed to be the only tool on top of XenServer, you can manage pools, administer VMs, back up your entire infrastructure, and most importantly – get a turnkey complete solution for any version of XenServer.

Having joined the Xen Project under the Linux Foundation, XCP-ng acts as a bridge connecting the user community and developers for the purpose of gathering anyone willing to become a contributor to its ecosystem and manifests the result of massive cooperation and collaboration between individuals and companies to deliver a product without limits – no restricted features, no requirements to purchase licenses.

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.

Simon Östling

You guys are great on support. Thank You.

Anthony Grevich

We are very excited about VyOS and use it as part of our products. VyOS convinces as a complete product with REST API and Wireguard support. The support is very fast and extremely competent.
