Some older legacy adapters have been replaced over time, and it is essential to upgrade them in your VM. Also, for high-performing VMs, it is strongly recommended to use paravirtualized devices instead of emulated devices. For example, VMXNET Generation 3 (VMXNET3) is the latest paravirtualized adapter with multi-queue support, IPv6 offloads, and MSI/MSI-X delivery interruption providing the best possible network performance for your VMs.
