Under certain conditions vmdir that ships with VMware vCenter Server, as part of an embedded or external Platform Services Controller (PSC), does not correctly implement access controls.

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).

The real limit depends by several aspects, included the hpyervisor, the CPU speed, the available RAM and (for external comunication) also by the physical NIC speed. For this reason, the Intel e1000 and e1000e vNIC can reach a real bandwidth bigger than the canonical 1 Gpbs link speed. But what about the vmxnet3 vNIC that can advertise also the 10 Gpbs link speed. What is […]
