Initial ESXi Setup Script

Automates the initial setup of an ESXi host after first installation and IP addressing.

First connects to ESXi host

NETWORKING:

Adds second vmnic to vSwitch0

Creates a second vSwitch (vSwitch1) with port group LAN and assigns 4 vmnics to it

Moves all VirtualMachines if exist to LAN portgroup and removes default VM Network portgroup

Renames Management Network portgroup to MGMT

Creates third vSwitch (vSwitch2) with an ISOLATED portgroup and no vmnics assigned

TIME CONFIGURATION:

Adds the following NTP time servers to the host:

0.vmware.pool.ntp.org

1.vmware.pool.ntp.org

2.vmware.pool.ntp.org

STORAGE:

Renames the default datastore 'datastore' to 'ESX1_local'
