Optimal SMB Parity

Hypervisor Platform	Licensing Model	Min Core / Socket Rules	Annual Est.	3-Year TCO	Trust / Vendor Lock-in

* Note: VMware core pricing modeled at standard list baseline ($120/core/yr with 16-core/socket minimum floor). Proxmox VE based on official Enterprise/Standard repository subscriptions (~$215/socket/yr). XCP-ng based on Vates enterprise support. Nutanix AHV includes base starter subscription. Microsoft Hyper-V modeled on Windows Server Datacenter 16-core pack per host.

Pathway A: Proxmox VE Migration

Recommended for SMBs seeking zero vendor licensing lock-in and direct KVM performance.

Export VM: Export VM from ESXi as OVF/OVA or use Proxmox Native ESXi Importer via vCenter API.
Storage Transformation: Utilize qm importovf or direct live storage streaming via virt-v2v -o local.
Driver Prep: Install VirtIO guest drivers (Red Hat VirtIO package) on Windows guests prior to migration to prevent BSOD.
Network Binding: Map vSphere distributed port groups to Proxmox Linux bridges (vmbr0, vmbr1) with VLAN tags.

Pathway B: XCP-ng & Xen Orchestra

Ideal for teams accustomed to VMware vCenter topology and turnkey web orchestrators.

Connect Xen Orchestra: Point XO directly to VMware vCenter host endpoint with administrative credentials.
V2V Warm Migration: Trigger Xen Orchestra live VM import; transfers disks while VM remains online with delta sync.
Install Xen Tools: Inject Xen Guest Agent for memory ballooning and clean shutdown signals.
Cutover: Perform 2-minute delta cutover with minimal guest application downtime.

Hardware Compatibility & Driver Checklist

Unlike VMware's restrictive and continuously deprecated ESXi Hardware Compatibility List (HCL), Linux-based hypervisors (Proxmox/Debian, XCP-ng) support standard server-grade Intel Xeon, AMD EPYC, SAS/SATA HBAs, and standard 10GbE/25GbE NICs.

Storage HBAs & RAID

LSI / Broadcom MegaRAID in IT mode (JBOD) recommended for Ceph & ZFS storage pools.

Network NICs

Intel X520/X710, Mellanox ConnectX-4/5 natively supported out of the box with zero custom VIBs.

Storage Protocols

Direct iSCSI initiator and NFS v3/v4.1 supported across all alternative hypervisors.
