Broadcom’s acquisition of VMware has prompted many Managed Service Providers (MSPs) and Cloud Service Providers (CSPs) to reconsider their virtualization infrastructure, especially for virtual machine management and vSAN storage. This shift has led to a growing interest in open-source alternatives that offer more control and cost-efficiency.
Exploring Open-Source Virtualization Platforms
For many service providers, Linux KVM (Kernel-based Virtual Machine) is the leading platform in server virtualization due to its reliability, performance, and strong open-source community support. Several open-source cloud management platforms (CMPs) support KVM and provide tools for virtualization, cloud task management, and automation. Key CMPs include:
- Apache CloudStack: Favored by midsize CSPs for its robust multi-tenancy and network management. However, its prescriptive architecture might not suit all organizations.
- OpenStack: Powers large cloud providers and telcos with nearly infinite flexibility and scalability, though it requires a skilled team to manage its complexity.
- Proxmox Virtual Environment (PVE): A straightforward hypervisor manager popular with software development teams for its ease of setup, though it lacks centralized management and multi-tenancy features.
- OpenNebula: Balances flexibility and complexity, making it a strong choice for mid-sized CSPs and enterprises building private clouds.

Choosing Your Hypervisor - VMware or KVM?
Coming from the open-source world, the tools above are all based around KVM. Some (OpenStack, CloudStack) have added features to allow them to oversee VMware clusters as well, but they are at their hearts KVM-first. New features support KVM first. Testing and performance tuning are focused on KVM. If your goal is to free yourself from the costs and uncertainty of the VMware ecosystem, building a stack around KVM and one of these open-source management stacks is the right answer.
The Complete View on Migrating from VMware to KVM
Transitioning from VMware to a KVM-based infrastructure is a complex process that involves more than just swapping hypervisors. VMware’s ecosystem encompasses a broad range of tools for virtual machine management, network management, backup, disaster recovery, availability, and storage. Therefore, a successful migration requires careful planning and execution.
The migration process typically involves several key steps:
- Map Existing Services to New Infrastructure: Understand how your current services will integrate into the KVM-based environment.
- Migrate Tenants, Groups, and Access Controls: Ensure that all user permissions and access controls are transferred securely.
- Migrate Network Services and Security Rules: Reconfigure and transfer network services and associated security rules.
- Deploy Backup and Disaster Recovery Solutions: Implement new systems to protect your data during and after the migration.
- Migrate VM Metadata: Transfer virtual machine configurations, ownership details, network parameters, and access controls.
- Migrate VM Data and Templates: Move the virtual machine data, which is often the most time-consuming part of the process.
Transferring the virtual disks, which involves moving large amounts of data, is one of the most critical and challenging aspects of this migration. This process inherently involves downtime, as even the fastest networks require time to transfer significant data volumes. Ensuring that your storage solution is compatible with the new infrastructure is crucial, and selecting a storage partner experienced in KVM and CMP environments is essential.
StorPool’s Role in VMware to KVM Migration
StorPool is designed to support cloud providers, especially those using open-source CMPs and KVM virtual machines. Many of our customers have successfully transitioned from VMware to KVM. They’ve found that KVM-based cloud management platforms offer a better fit than repurposed enterprise technologies like VMware or RedHat OpenShift.
KVM is not the only alternative to VMware. If you are interested in exploring other virtualization options for your cloud, we recommend reading “Choosing the Right Hypervisor for Your Cloud” from our friends at ShapeBlue.
StorPool’s development team has prioritized Linux KVM as the preferred virtualization method for development and production. We have built significant expertise around KVM performance and reliability. We often advise our customers on their KVM infrastructure and have supported numerous clients in migrating from VMware to KVM.
