1.2.1 Pregunta general

Right click on the Desktop Pool in which you want to add Managed Desktops and click Add Desktops option. A window will be opened show the following options:

48 Choose Import exisitng computers from hosts.

IMPORT EXISTING COMPUTERS FROM HOSTS

If you already have desktop instances running on your virtualization host then you can import them into the VDI management console.

A wizard will open containing the list of Virtualization Hosts on the left side of the wizard and the Desktops on that Virtualization Host will be displayed in the top right list of the window after clicking on that Virtualization Host.

You can now select the Unmanaged Desktops and click Add Selected Desktops. This will move the selected desktops to the bottom right list.

49 After you are done click the Finish button.

You can now see the Managed Desktops added to the Desktop Pool. However, these desktops cannot be assigned to users until the Propalms VDI Desktop Agent is installed on them. Until this happens, the imported desktops remain in Partially Imported (highlighted in red) state. Once, the agent is installed and carries out the configuration process, the state of these desktops changes to Fully Imported and can be assigned to users.

INSTALL VDI DESKTOP AGENT

For performance and communication reasons vendor specific client tools should already be installed on the virtual desktops. The Propalms VDI Desktop Agent is a set of Propalms tools installed inside each virtual machine to provide information about the active user on the virtual machine. It also enables administrators to send control messages to the virtual desktops.

To add the VDI agent to each desktop you will need access either directly to the console or through remote desktop if it is already enabled.

NB: The VDI Desktop Agent ensures that remote desktop is enabled whenever it starts.

There is a feature in the VDI management console allowing an administrator to right click a desktop and console into the virtual desktop.

Download and save the VDI Desktop Agent fromhttp://<ConnectionBrokerNameORIPAddress>/ConnectionBroker

Open a command prompt and navigate to the directory where the agent setup file exists.

Once you are in the same folder (from the command prompt) as the agent setup, run the following command: VDIDesktopAgentSetup-2.1.exe /S /BrokerHost="< ConnectionBrokerNameORIPAddress >"

This will install the agent on the desktop and set the environment for the VDI Connection Broker host.

You can now connect to the virtual desktop by logging in as a valid user through either the VDI Desktop Client or VDI Web Client.

CLONE MANAGED DESKTOPS DYNAMICALLY

A Golden Image, in terms of Propalms VDI, is a base desktop which can be cloned and new desktops can be created from it. The difference between template and golden image is that in a template, only the configuration is the same. However, in golden image the configuration as well as the data is cloned.

CREATE BASE OS IMAGE FOR GOLDEN IMAGE

In order to create a golden image, the first task is to create a Virtual Machine (Windows 7). This task is generally carried out from outside of the Propalms VDI product using the hypervisor client. You can either install Windows from CD/DVD, ISO image or alternatively use P2V conversion tools.

NB: Please refer to the VMware documentation for creating a new VM image. We recommend a clean desktop image is used.

1. Enable local administrator account on the Windows 7 VM. This account is disabled by default. 2. Install VMware Tools.

3. Add the Windows 7 VM to your domain.

4. Enable Remote Desktop connections and select domain users or groups who you want to access the desktops.

52 5. Enable Windows Firewall to allow Remote Desktop connections.

6. Install Propalms VDI Desktop Agent.

Download and save the VDI Desktop Agent installer from

http://<ConnectionBrokerNameORIPAddress>/ConnectionBroker

Open a cmd prompt in elevated mode using Run as Administrator option.

Enter the following command from the directory where you saved the agent installer VDIDesktopAgentSetup-2.1.exe /S /BrokerHost="< ConnectionBrokerNameORIPAddress >"

53 This will install the agent on the desktop and set the environment for the VDI Connection Broker host.

7. For production environments, the Windows 7 desktop image needs to be licensed and activated using a Microsoft Volume Activation key.

8. Finally, install any applications that you wish to include with the Golden Image. These will be available for all clones of this image.

IMPORTING AND CONVERTING VM TO GOLDEN IMAGE

Select the Desktop Center and on the right side of the screen choose Golden Images. On the Actions menu choose Import Golden Image.

54 Select the image that you have configured to be your Golden Image and choose Add Selected Desktops then click Finish.

You can now see the Managed Desktops added to the specified desktop center as a golden image.

Alternatively you can right click any desktop in the pool and select Convert to Golden Image.

55 The desktop image will be removed from the Managed Desktop page and visible under the Golden Images tab.

CREATE GOLDEN IMAGE

You can create a VM template in which to install the golden image by choosing the Create Golden Image option. A wizard will open asking to enter the Task Name and select the type of Operating System Template you want to use for the new golden image and click Next to proceed.

Enter the MD Name you want for the image as well as the host in Target Virtualization Host field to specify the host where the image would be created. You can also specify to use a template to create the image in this step by checking use template checkbox. Click Next to continue.

56 You can specify the configuration of the image by specifying the Ram and umber of CPUs to be allocated to it. Click Next to continue.

You can specify the domain configuration in this step. The image can join a workgroup or a domain. You need to specify the domain credentials for the latter. Also, you can choose the time zone. Click Next to continue.

57 You can attach various devices to the image in this step. For each device, you will be required to specify the basic configuration settings. Click Next to continue.

Enter the password for the Administrator account for the newly created image and click Next to continue.

NB: This create option simply create and empty Virtual Machine in VMware which needs an operating system installed into it for it to function as a working Golden Image. You can run the Golden Image and connect to it using VMware tools in order to install the OS.

GOLDEN IMAGE OPERATIONS

By default, the Golden Image will be in offline mode. Select the Golden Image you want to operate on and right- click on it.

The golden image can be brought into running mode by clicking Run Golden Image.

Different operations like Pause/Suspend, Resume, Stop and Force Off as well as Console can also be performed on the image.

The configuration of a golden image can be edited. New hardware can be added and the existing one can be removed in a fashion similar to that of managed desktops.

59 Removing the image will remove the golden image from the Propalms VDI Management as well as the Virtualization Host.

SAVING MANAGED DESKTOP CONFIGURATION AS TEMPLATE

A Configuration Template, in terms of Propalms VDI, is a configuration set which can be directly applied to a managed desktop during creation. Configurations include values for RAM allocation, CPU count, Devices attached and their specifications, etc. When the desktop is created you can simply select a template and apply that configuration set to the desktop being created instead of specifying these values individually for each of them. To store the configuration of a given desktop as a template, right-click on a desktop and click Save As Template.

The template will appear under the Configuration Templates section of the console. Here you can Delete, Edit or view Properties of the template.

DEPLOYING MANAGED DESKTOPS FROM GOLDEN IMAGE

Right click on the Desktop Pool in which you want to add Managed Desktops and click Add Desktops option. Choose the option to Clone Managed Desktops Dynamically.

Enter a task name on the next screen.

61 Enter the domain related information of the desktops being created. If a domain is specified, then the domain credentials also need to be entered. Also, select the time zone and click Next.

A list of golden images is displayed. Select an image and click Next.

The next screen asks about naming the disks, providing 2 options. On selecting Automatically name the Disks for the Desktops in the same pool, the new desktop’s disk is created in the same storage pool as the golden image itself. On selecting Automatically name the Disks for the Desktops in the different pool the desired storage pool is to be selected. In this case, the new desktop’s disk is created in the selected storage pool.

62 Enter the password for the Administrator account on the desktop and click Next.

These desktops can be created immediately by selecting Create desktops now or on demand by selecting Create desktops on user logon. Alternatively desktops can be scheduled for creation using the Schedule the creation of desktops option.

63 You can now see the Desktops added to the pool. You will have to start the desktops to initiate the Sysprep process in readiness for users logging in.
