.SYNOPSIS
|
|
Applies a pre-assigned static IP from VMware guestinfo at boot.
|
|
|
|
.DESCRIPTION
|
|
Called by the CI-StaticIp Task Scheduler task at system startup (SYSTEM
|
|
account). Reads guestinfo.ip-assignment written by the host orchestrator
|
|
before vmrun start. If present, disables DHCP and applies the static IP
|
|
before WinRM has a chance to start on a DHCP address, eliminating the
|
|
20-180 s VMware-Tools IP-detect polling loop.
|
|
|
|
If guestinfo.ip-assignment is absent (template used standalone or
|
|
ip_pool not configured), exits 0 immediately — DHCP runs normally.
|
|
|
|
Install into the template VM:
|
|
1. Copy this script to C:\CI\ci-static-ip.ps1
|
|
2. Create a Task Scheduler task:
|
|
Name: CI-StaticIp
|
|
Trigger: At System Startup
|
|
Action: powershell.exe -NoProfile -NonInteractive
|
|
-ExecutionPolicy Bypass -File C:\CI\ci-static-ip.ps1
|
|
Run As: SYSTEM
|
|
Run with highest privileges: Yes
|
|
3. Take the BaseClean snapshot from powered-OFF state.
|
|
|
|
The VMCI channel (vmware-rpctool) does not require TCP/IP — it works
|
|
via the VMware virtual hardware interface, so guestinfo is readable
|
|
before the NIC is configured.
