virt-manager
The virt-manager application provides a desktop user interface for managing virtual machines through libvirt, primarily targeting KVM VMs but also managing Xen and LXC. As a free and open-source clearVM alternative for Linux, BSD, and various Linux distributions like Gentoo, Fedora, and Debian, it's perfect for users who prefer a graphical interface. Its features include SSH and VNC Viewer support, along with live migration capabilities.
Xen
Xen.org is home to the Xen hypervisor, a powerful open-source industry standard for virtualization. As a native (bare-metal) hypervisor, it offers robust virtualization services on Linux, making it a strong clearVM alternative for high-performance and secure environments. Xen is renowned for its efficiency and ability to host multiple guest operating systems with minimal overhead.
Portable Virtualbox
Portable VirtualBox is a free and open-source tool that allows users to run any operating system from a USB stick without separate installation. This Windows-based clearVM alternative is highly convenient for those needing a portable virtualization solution, offering the full functionality of VirtualBox in a self-contained package. Its portability feature makes it unique among the alternatives.
VMware vSphere Hypervisor
VMware vSphere Hypervisor (based on ESXi) is a free bare-metal hypervisor that virtualizes servers, enabling consolidation of applications on less hardware. Available for Windows, Linux, and supporting NVIDIA vGPU and AMD MxGPU, it's a commercial yet free clearVM alternative that offers enterprise-grade virtualization capabilities, making it a reliable choice for robust server infrastructures.
Microsoft Hyper-V Server
Microsoft Hyper-V Server is a stand-alone, commercial product that provides a reliable and optimized virtualization solution for improving server efficiency. Available for Windows and Linux, it serves as a strong clearVM alternative, especially for organizations integrated into the Microsoft ecosystem. Its native hypervisor capabilities ensure robust performance for virtualized workloads.
Citrix Hypervisor
Citrix Hypervisor (formerly XenServer) is a leading virtualization management platform optimized for application, desktop, and server virtualization infrastructures. As a freemium and open-source clearVM alternative available for Windows, Linux, and supporting various GPU technologies, it offers a comprehensive suite of features for enterprise-level virtualization needs, including robust hypervisor capabilities.
With a diverse range of clearVM alternatives available, from free and open-source options like VirtualBox and KVM to enterprise-grade solutions such as Proxmox and VMware vSphere Hypervisor, you have plenty of choices to meet your specific virtualization requirements. Carefully consider your budget, technical expertise, and the scale of your virtualization project to select the best fit for your infrastructure.
