As explained in KB 2107518, on February 16th 2024, VMware announces the End Of General Availability of the Free vSphere Hypervisor (ESXi 7.x and 8.x).

Reading Time: 3 minutesMolti utilizzano come laboratorio ambienti nestested, spesso basati su VMware Workstation/Player/Fusion dato che queste soluzioni di virtualizzazione sono perfettamente in grado di virtualizzare anche hypervisor di tipo 1 (baremetal) come ESXi, ma anche Hyper-V, Xen e KVM. Se però avete già provato ad installare VMware ESXi 7.0 all’interno di una VM su VMware Workstation vi sarete accorti che non è possibile (lo stesso problema c’è con Fusion e Player).
