Overall Satisfaction with Proxmox VE
I required a virtualization environment that was free, easy to set up, was able to cluster, and worked on existing hardware. After trying several other solutions, I decided on Proxmox VE. It is currently being used in a Lab environment to build test servers for training and application development before going into production.
- 100% free. Unlike other products, Proxmox is completely free.
- Supports both UEFI and BIOS virtualization.
- Supports Windows, Linux, and containers host VMs.
- Several options are available for storage. CephFS, the clustered built-in network storage, needs to be installed via the console or ssh. Other options like iSCSI do not support host migration.
- Proxmox has allowed us to provide completely free training and an application development environment by reusing desktop hardware.
I have tried VMWare ESXi, as that was free, but then quickly found out that for cluster I needed the paid version.
Hyper-V server was also tried but did not have an easy high available cluster install without creating a separate domain.
XenServer was a great free alternative, but recently Citrix has limited what the free version can do. The opensource community then branched off and created XCP-NG project. I tried XCP-NG but it does not yet have UEFI support.
