Following sustained user feedback and the recent in-house development of a provisioning module for our billing platform, WiseCP, we have taken the difficult decision to deprecate SolusVM 2 as our primary VPS management panel.

And, as of 23 December 2025, C-Servers will begin to market VirtFusion-based VPS services on our main offerings, under the MultiVPS and JumboDisk product tiers - starting with our new server in Falkenstein, Germany.

The VirtFusion platform will also be adopted progressively across product launches and new service lines in additional locations, as well as existing VPS services, with customer migrations planned to begin in 2026, ensuring a controlled and smooth transition to our existing customers - as much as possible.

Why Transition from an Established Platform?

This decision was not taken lightly.

When SolusVM was originally selected, it followed extensive internal testing and was, at the time, aligned with our requirements for usability and customer experience. However, as our infrastructure and customer base have grown, several structural and operational limitations became progressively clear.

The primary driver behind this transition is network and NAT handling. SolusVM’s long-standing lack of native NAT functionality has led us to seek external implementations, which introduced complexity and operational friction. Over the past 12 months, we observed repeated customer difficulties related to NAT usage, resulting in avoidable support overhead and, of course, the natural inconvenience it brought.

In addition, several other usability difficulties influenced our decision, including:

» Manual intervention requirements when virtual machines fail to restart automatically after host reboots, impacting overall uptime,

» Specific, occasional Open vSwitch-configured network discovery behaviors causing (very punctually) added latency, which only started to occur after a relevant number of VPS users were on dedicated servers;

» Backup tooling limitations, particularly performance and throughput.

Advantages of VirtFusion

With VirtFusion, we are introducing a more modern, resilient, and scalable architecture. We are explicitly abandoning our previous NAT system through socat and NAT64/DNS64, and we are focusing on a DNS-direct, NAT-direct solution.

Whenever possible, we'll use MacVTap; but on NAT solutions, we're now using libvirt bridging paired with Cloudflare DNS servers.

Other improvements include:
» Expanded NAT port allocations, increasing from 10+5 to 20+3 ports,
» Full support for standard IPv4-to-IPv4 service hosting, compatibility with all common web hosting control panels, and customer-managed NAT port ranges.

These changes significantly enhance flexibility, performance, and overall value for VPS customers—particularly for networking-intensive workloads.

Beyond networking, customers will also experience relevant improvements in usability, performance consistency, and operational/uptime reliability, delivered through a platform that is both widely adopted and well-established in the industry.

Importantly, this transition does not materially affect pricing, which solely increases on the range of 0,10 USD per month for newer customers. Of course, upon migration, existing customers will retain their current pricing with C-Servers.

So, when will it be available?

The first VirtFusion-based MultiVPS plans will be available for immediate deployment starting at 11h00 GMT +0, at our website.

A new chapter awaits - and with you, more than ever before, we are making sure you C-Servers.
Merry Christmas!

Many providers use SolusVM 1. I have seen and used Racknerd's control panel and used their ticket system to request an .iso mount. My experience with KVM and .iso mounts is limited, and I assume that Racknerd's implementation is essentially "standard". My feeling is that all providers with SolusVM 1 have the same look and feel, or only minor differences.

-> So, can you recommend providers who support KVM, custom .iso mounts, and console access? The console would interface with the booted .iso on the KVM VPS with an unformatted drive. In addition, they must also have a user interface other than SolusVM 1, either a competitor or a custom control panel.

I want to be sure that instructions I may write can be easily applied in a generic way to most providers with those features. Does that answer the "why"?

Inflation
Devaluation of Currency
Just because the owners/devs want to do it
The owners/devs want their product to be "enterprise only"
And of course there can be many other reasons as well

But how much price increase do you think is fair & would not be toll on your pocket if you also get assurance that price increase for a particular software will never be more than a fixed percentage every year?

So it looks like they're trying to sell it now that they've used cPanel as a proof-of-concept to spike pricing.

If this goes through we'll see another cPanel price hike within 12 months. I'll bet dinner on that.

• Solus.io finally launches at $4/m/core with Solus VM1 set to sunset 12mo to 18mo after initial
• WHMCS sunsets lifetime licenses with the launch of v8.0. To add to the displeasure they remove the "unlimited customers" option and requires everyone pay $0.30/month/active or similar.
• More mergers/buyouts as datacenters continue to roll out products competing with their own users.
• Plesk removes their unlimited domain option.
• Directadmin prunes back the amount of OS' they support to allow them to make it easier to maintain the product.

#2 I stole from @qps.
