VMware PowerCLI 13.0.0.20829139 – how to install with Python 3.7.9 on Windows required for ImageBuilder

VMware vSphere Hypervisor (ESXi 8.x) – does not natively support USB NIC and upon a reboot the USB NICs are not picked up until much later in the boot process which prevents them from being associated with VSS/VDS and their respective portgroups. To ensure things are connected properly after a reboot you will need to add something like the following in /etc/rc.local.d/local.sh which re-links the USB NIC along with the individual portgroups as shown in the example below

[root@ra-vmware8-01:~] vi /etc/rc.local.d/local.sh
esxcfg-vswitch -L vusb0 vSwitch0
esxcfg-vswitch -M vusb0 -p „Management Network“ vSwitch0
esxcfg-vswitch -M vusb0 -p „VM Network“ vSwitch0
esxcli network vswitch standard uplink add -u vusb0 -v vSwitch0
