Virtual Machines - Reimage

Service:

Compute

API Version:

2024-11-01

Reimages (upgrade the operating system) a virtual machine which don't have a ephemeral OS disk, for virtual machines who have a ephemeral OS disk the virtual machine is reset to initial state. NOTE: The retaining of old OS disk depends on the value of deleteOption of OS disk. If deleteOption is detach, the old OS disk will be preserved after reimage. If deleteOption is delete, the old OS disk will be deleted after reimage. The deleteOption of the OS disk should be updated accordingly before performing the reimage.

POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachines/{vmName}/reimage?api-version=2024-11-01

URI Parameters

Name	In	Required	Type	Description
resourceGroupName	path	True	string minLength: 1 maxLength: 90	The name of the resource group. The name is case insensitive.
subscriptionId	path	True	string minLength: 1	The ID of the target subscription.
vmName	path	True	string	The name of the virtual machine.
api-version	query	True	string minLength: 1	The API version to use for this operation.

Request Body
