When Broadcom acquired VMware for $61 billion in 2023, the enterprise virtualization world held its breath. Now, two and a half years later, that breath has turned into a scream.
Tesco, one of the UK’s largest retailers, is migrating 40,000 server workloads off VMware and suing Broadcom for over £100 million in the UK’s High Court. The retailer alleges Broadcom engaged in “abusive conduct” after hiking VMware prices by approximately 175% and forcing customers onto subscription bundles they never asked for.
But Tesco isn’t alone. This is the tip of an iceberg that’s been growing since Broadcom dismantled VMware’s licensing model in late 2023 — and every IT manager running VMware infrastructure should be paying attention.
What Broadcom Actually Changed
When Broadcom completed the VMware acquisition in November 2023, it didn’t just buy a virtualization company. It rewrote the rules of the game.
Perpetual licenses? Gone. The à la carte model where you bought vSphere, added vCenter, and tacked on vSAN separately? Replaced with two subscription bundles: VMware vSphere Foundation (VVF) and VMware Cloud Foundation (VCF). And the pricing shifted from per-CPU socket licensing to per-core licensing.
That last change is where the real pain lives. Under the old model, a server with two 16-core CPUs needed two CPU licenses. Under the new model, every physical core gets licensed — that same server now requires 64 core licenses. Multiply that across a data center running hundreds of hosts, and the math gets ugly fast.
But the pricing story gets worse. Broadcom imposed a 16-core minimum per CPU, regardless of actual core count. An eight-core chip still gets billed as 16 cores. And for some SKUs, there’s a 72-core floor per purchase — meaning small environments and edge deployments pay for capacity they literally don’t have.
The Price Hikes Nobody Expected
The numbers coming out of court filings and regulatory complaints paint a picture of systematic price escalation:
- Tesco — 175% increase, resulting in the £100M lawsuit and 40,000-workload migration
- AT&T — 1,050% increase, documented in a federal court filing
- A UK university — from £40,000/year to £500,000/year (a 1,250% jump)
- Computershare — 900% to 1,400% increase range
These aren’t outliers. A survey of enterprise buyers found that 73% expect prices to more than double, while 12% anticipate increases between 301% and 500%. The reported range across the industry sits at 300% to 1,500%.
Why Tesco’s Lawsuit Matters More Than You Think
Tesco purchased VMware perpetual licenses in 2021 with support and upgrade rights running through 2026 — plus an option to extend. That was a standard enterprise software purchase. You buy the license, you get the right to use it, you pay for support and patches.
After Broadcom acquired VMware, it stopped selling support for perpetual licenses. If you wanted patches, security updates, or the ability to upgrade, you had to subscribe to one of the new bundles (much like how Microsoft’s frequent Patch Tuesday cycles keep enterprises on a perpetual upgrade treadmill). Essentially, you’re paying again for software you already own.
Tesco is also suing Computacenter, the reseller that originally sold them the licenses. The legal argument cuts deep: if a vendor can alter support terms for perpetual licenses after an acquisition, what does “perpetual” actually mean?
The case tests whether a supplier can revoke support obligations that were explicitly promised. Previous cases like HP v Oracle (Itanium) set precedent where courts compelled vendors to maintain support. But SAP v Diageo favored the vendor’s license interpretation. The Tesco case could go either way — and either outcome will reshape how enterprise software contracts are written.
This Is Bigger Than One Lawsuit
Tesco’s situation is the most visible, but the exodus is already underway across the industry.
Gartner’s 2026 Strategic Roadmap found that only 7% of organizations remain fully committed to VMware. The analyst firm projects that by 2026, 50% of enterprises will initiate proofs-of-concept for alternative platforms. Forrester had already forecast that 20% of enterprise VMware customers would begin migrating away.
The European cloud infrastructure trade association CISPE has complained to the European Commission about what it calls “massive and unjustifiable hikes in prices, the re-bundling of products, altered basis of billing and the imposition of unfair software licensing terms that restrict choice and lock-in customers and partners.”
And then there’s the Dutch court ruling where a judge ordered Broadcom to continue providing support while the Dutch Ministry of Infrastructure migrates away — with a potential penalty of up to $29 million for non-compliance. The court found that Broadcom “acts in breach of its duty of care” by failing to provide adequate exit support for systems managing vital national infrastructure.
Where Companies Are Actually Going
The migration destinations have crystallized by mid-2026. Organizations aren’t rushing to cloud — most are moving to alternative on-premises hypervisors:
- Proxmox VE — Open source, no licensing fees. Adoption is surging among small-to-mid fleets. Support subscriptions start under $1,000 annually for small clusters.
- Nutanix AHV — Commercial hyperconverged platform. Migration tools like Nutanix Move are mature. Higher-end enterprise option.
- Microsoft Hyper-V / Azure Stack HCI — Included with Windows Server. Strong choice for Windows-dominant environments.
- XCP-ng — Community-supported XenServer derivative. Balances open-source cost with enterprise features.
The dominant strategy is what practitioners call “dual-hypervisor” — keeping critical, deeply VMware-integrated workloads on VMware while migrating everything else. It’s pragmatic, but it means organizations are effectively running parallel infrastructure stacks with all the operational complexity that entails.
The Real Cost of Migration
Moving off VMware isn’t free. Realistic migration timelines for mid-size estates run 12 to 18 months. Organizations need to plan for parallel-run costs — paying for both VMware and the new platform during transition. There’s training to budget for ($5,000 to $20,000 for team skill development). And there’s the operational risk of running a new platform in production.
But the financial calculus is clear: staying on VMware at 300% to 1,500% price increases doesn’t make sense for most organizations. The question isn’t whether to migrate — it’s how fast you can do it without breaking production.
The Lesson for Every IT Manager
If your infrastructure runs on VMware, here’s what you need to do right now:
- Know your renewal date. If it’s more than 12 months out, you have runway. If it’s within 6 months, you need to start evaluating alternatives now.
- Get a competing quote. Even if you don’t plan to migrate immediately, having a documented alternative from Nutanix, Proxmox, or Microsoft gives you a serious edge in renewal negotiations. The single largest cost variable is your credible willingness to walk.
- Inventory your workloads. Not everything needs to stay on VMware. Standard Linux and Windows servers are prime migration candidates. Deep VMware-integrated workloads (NSX, specific backup hooks) are the ones that need to stay.
- Read your contract. What does “perpetual” actually mean in your agreement? Does it include support obligations? The Tesco case will set precedent here.
I’ve written about Linux server monitoring and infrastructure hardening before — the infrastructure layer is where most organizations have the least visibility but the highest financial exposure. This Broadcom situation proves that point painfully well.
The virtualization market hasn’t been this fractured in 30 years. VMware was the default — the safe choice. Broadcom turned that safety into a liability, and the enterprises that saw it coming are already ahead.
For the rest, the clock is ticking.
