You can create multiple clones from a template and make minor modifications to each clone. This is useful in seeing the effects of these changes on the system. Both clones and templates are virtual machine instances. The difference between them is in how they are used. For the created clone to work properly, information and configurations unique to the virtual machine that is being cloned usually has to be removed before cloning.
The information that needs to be removed differs, based on how the clones will be used. The information and configurations to be removed may be on any of the following levels:. Platform level information and configurations include anything assigned to the virtual machine by the virtualization solution. Guest operating system level information and configurations include anything configured within the virtual machine.
Examples include SSH keys. Application level information and configurations include anything configured by an application installed on the virtual machine. Examples include activation codes and registration information. This chapter does not include information about removing the application level, because the information and approach is specific to each application.
Followed all these steps. Via html on the browser I can launch the workstation however from the client it spins and eventually disconnect. On the admin console I get a warning that the pending session has expired. Thanks for your help. Hi Carl, I need to know on selection cluster some reason i am choosing an cluster and users are working later my management provided 3 machine which i need to create other cluster. Later can i change the cluster setting to the Desktop pool , will it affect any?
When Instant Clones deletes the machine and re-creates it, then the new machine should go on the new cluster. It Means it will all the machine in the pool and recreate it in new Cluster is it? Also one more think we cant able to recompose one machine particularly in Instant clone?
In vCenter, if you clone the VM manually and use a customization specification, does sysprep complete without issue? I saw the instructions, but kind of worried to upgrade current 7. Navigation This post applies to all VMware Horizon versions 8.
Composer does the same. If you have six hosts and three datastores containing instant clones, then Horizon creates 18 parent virtual machines. Composer does not need parent virtual machines. See the Smart Provisioning YouTube video for an overview. Persistent disks are not supported with Instant Clones. See VMware Horizon 7 sizing limits and recommendations for maximum cluster size and maximum number of virtual machines per cluster.
Ensure vSwitch has sufficient ports for the new virtual desktops. Instant clones require static port binding with the elastic port allocation. Do not change the port binding to ephemeral.
Lower the DHCP lease time too. DHCP should be highly available e. Adjust accordingly. The master image should be in the same vSphere cluster where the instant clone virtual desktops will be created. If you upgrade vCenter to 6. Afterwards, take a new snapshot of the master image and perform a push operation. Disk space One or more LUNs datastores for storage of the virtual desktops. See VMware Horizon 7 sizing limits and recommendations for maximum virtual machines per datastore.
By default, Replicas are copied to each LUN that contains virtual desktops. If the master virtual desktop has 4 GB of RAM configured and if none of its memory is reserved then each linked clone will have a 4 GB. To reduce the size of the. Whatever memory is reserved will be subtracted from the. Instant Clone Delta disks — Delta disks start small whenever the virtual desktop boots and grow until the user logs off of the virtual desktop and it reboots.
More video memory means more client monitors. The maximum number of displays and maximum resolution of client monitors depends on the ESXi version, the Horizon version, and the Windows version with newest versions providing the greatest number of client monitors. Join domain — Join the master VM to the domain.
Run gpupdate on the master after moving the VM to the correct OU. New Instant Clones do not immediately refresh group policy so the group policy settings must already be applied to the master VM. Snapshot — Shut down the master image and take a new snapshot. On the left, under Inventory , click Desktops. On the right, if you select an existing pool, you can click Duplicate to copy the settings to a new pool. On the right, click Add. In the Type page, select Automated desktop pool.
Notice that Composer is no longer an option. In the User Assignment page, select Floating , and click Next. In the Storage Optimization page, if you want to use storage tiering, check the box for Select separate datastores for replica and OS disk. Click Next. In the Desktop Pool Identification page, do the following: Give the pool a unique ID, which is not shown to the users. Enter a Display name , which is shown to the users.
Otherwise, if you intend to delegate administration of this pool, then select an Access group that the delegated administrators have been assigned to. Make sure the naming pattern does not conflict with any existing machines. Remember, the maximum computer name length is 15 characters. In Desktop Pool Sizing , enter the maximum number of desktops to create. Select Provision all machines up-front to create all of the machines now.
Or select Provision machines on demand , which tells Horizon to create the machines up to the maximum as users connect. As users connect, Horizon creates more machines to try to keep this number of spare machines running and waiting for a new connection. In the vCenter Settings page, most of these are self-explanatory. Click Browse next to each option, and make your selection. Scroll down for more settings.
Datastores — select one or more datastores on which the virtual desktops will be placed. When selecting Networks , you can use the Network from the parent image, or uncheck the box and select a different network.
Click Next when done. Change the selection to Select a category folder from the folder list. You can type in a new category, or select an existing one. Then click Submit. In the Desktop Pool Settings page, Horizon Enterprise Edition lets you select a Session Type , which means you can optionally publish applications from virtual desktops.
Change the selection for Logoff after disconnect to After , and specify a disconnect timer. You can also use Group Policy to configure this. The GPO overrides the pool setting. You can allow users to restart their machines. Leaving it set to Always is strongly recommended. The other options cause the delta disk to grow, and will cause data loss surprise for the users when you later push a new image.
Instant Clones floating assignment pools always refresh on logoff. Reclaim VM disk space is also an option for Dedicated assignment pools.
See Session Collaboration for details. You can type paste into the AD container field. Consider checking the box next to Allow reuse of pre-existing computer accounts. In the Ready to Complete page, you may entitle users now, or leave it unchecked and do it later.
Click Submit. If you opted to add entitlements now: In the Add Entitlements window, click Add. Find a group that will have permission to log into these desktops, and click OK.
Then click OK. You might have to click the refresh icon on the top right to see the new pool. Click the link for the pool name. On the Summary page, if you scroll down, the vCenter Server section has a State field where you can see the status of the pool creation process. It takes several minutes to publish the master image snapshot. After the snapshot is copied to the Replica, vSphere creates a digest file for View Storage Accelerator, which takes a few more minutes.
To refresh it, scroll up and click the refresh icon. In high-density pools, Instant Clones are forked from the cp-parent machine. In low-density pools, Instant Clones are cloned from the cp-replica. For higher-density pools, there is a cp-parent at the bottom of the hierarchy. For Smart Provisioning of lower-density pools, there is no cp-parent. Entitle Virtual Desktops To make a pool accessible by a user, it must be entitled. Click the link for a pool name.
