How to Create a Private Cloud from Host Groups

Updated: November 1, 2013

Applies To: System Center 2012 - Virtual Machine Manager, System Center 2012 R2 Virtual Machine Manager, System Center 2012 SP1 - Virtual Machine Manager

You can use this procedure to create a private cloud from resources in one or more host groups in System Center 2012 – Virtual Machine Manager (VMM). You can create a private cloud from host groups that contain a single type of host, or from host groups that contain a mix of Hyper-V, VMware ESX, and Citrix XenServer hosts.

noteNote
You can also create a private cloud from a VMware resource pool. For more information, see How to Create a Private Cloud from a VMware Resource Pool.

Account requirements   You must perform this procedure as a member of the Administrator user role or as a member of the Delegated Administrator user role where the administrative scope includes the host groups that you want to use for the private cloud.

Prerequisites

Before you create a private cloud, make sure that the following prerequisites are met:

  • Configure the fabric and add hosts to VMM management by using the procedures in the following sections:

  • If you want to provide self-service users the ability to store virtual machines to the VMM library, create a library share, or create a folder in a library share that will serve as the storage location. Realize that self-service users must have the Store and re-deploy permission to store their virtual machines.

    ImportantImportant
    The library share location that you designate for stored virtual machines must be different from the shares that you designate as read-only resource locations for the private cloud. Also, the path or part of the path must be unique when compared to the user role data path that is specified for a self-service user role. For example, if the user role data path for a self-service user role is \\VMMServer01\Finance, you cannot create a stored virtual machine path of \\VMMServer01\Finance\StoredVMs. However, if the user role data path is \\VMMServer01\Finance\FinanceUserRoleData, you could specify \\VMMServer01\Finance\StoredVMs as the stored virtual machine path, as the full path is unique. You could also create entirely separate library shares.

    Realize that you configure the stored virtual machine path and read-only library shares when you run the Create Cloud Wizard. The self-service user role data path is specified when you create a self-service user role or modify the properties of a self-service user role.

    For example, outside VMM, create the \\VMMServer01\Finance\StoredVMs path, and then add the VMMServer01\Finance library share to the VMM library.

  • If you want to assign read-only shares to the private cloud, where administrators can store read-only resources such as .iso files that they want to make available to self-service users, make sure that one or more library shares exists that you can assign as the read-only library shares. Realize that self-service users must have the Author permission to access the resources.

    ImportantImportant
    The library shares that you designate as read-only resource locations for the private cloud must be unique when compared to the library share or shares that are used for stored virtual machines and for the user role data path that is specified for a self-service user role.

    For example, you can use the SEALibrary and the NYLibrary library shares.

    noteNote
    For more information about self-service user permissions, see How to Create a Self-Service User Role in VMM.

To create a private cloud from host groups

  1. Open the VMs and Services workspace.

  2. On the Home tab, in the Create group, click Create Cloud.

    The Create Cloud Wizard opens.

  3. On the General page, enter a name and optional description for the private cloud, and then click Next.

    For example, enter the name Finance, and the description Private cloud for virtual machines and services in the finance department.

  4. On the Resources page, do the following:

    1. Click Host groups.

    2. Select the check box next to each host group that you want to add, and then click Next.

      For example, select the check boxes next to Seattle\Tier0_SEA, Seattle\Tier1_SEA, New York\Tier0_NY and New York\Tier1_NY, and then click Next.

  5. On the Logical Networks page, select the check box next to each logical network that you want to make available to the private cloud, and then click Next. Only logical networks that are associated with physical network adapters on hosts in the selected host groups appear in the list.

    For example, select the check box next to BACKEND, and then click Next.

  6. On the Load Balancers page, select the check box next to each load balancer that you want to make available to the private cloud, and then click Next. Only load balancers that are associated with the selected host groups appear in the list.

    For example, select the check box next to LoadBalancer01.contoso.com, and then click Next.

    TipTip
    In the Create Cloud Wizard, if you do not have a fabric resource configured, you can click Next to move to the next page. Realize that you can add or remove private cloud resources and modify other private cloud settings after you complete the wizard. To do this, right-click the private cloud, and then click Properties.

  7. On the VIP Profiles page, select the check box next to each VIP template that you want to make available to the private cloud, and then click Next.

    For example, select the check box next to Web tier (HTTPS traffic), and then click Next.

  8. On the Storage page, select the check box next to each storage classification that you want to make available to the private cloud, and then click Next. Only storage classifications for storage pools that are assigned to the selected host groups appear in the list.

    For example, select the check boxes next to GOLD and SILVER, and then click Next.

    noteNote
    If you do not have storage that is managed by VMM, click Next.

  9. On the Library page, do the following:

    1. Next to the Stored VM path box, click Browse. In the Select Destination Folder dialog box, expand the library server, click the library share or the folder in a library share that you want to use as the location for self-service users to store virtual machines, and then click OK.

      For example, if you created the folder that is described in the Prerequisites section of this topic, click the StoredVMs folder in the VMMServer01\Finance library share.

    2. In the Read-only library shares area, click Add, select the check box next to one or more library shares where administrators can provide read-only resources to cloud users, click OK, and then click Next.

      For example, select the check box next to the SEALibrary library share and the NYLibrary library share.

  10. On the Capacity page, set capacity limits for the private cloud, and then click Next. You can either accept the default values, or clear the Use Maximum check boxes and set quotas for the following resources:

     

    Quota Type Description

    Virtual CPUs

    Sets a limit on processing capacity within the private cloud that is equivalent to the capacity that can be provided by a specified number of CPUs. Applied against running virtual machines. Setting a CPU quota does not guarantee contiguous capacity; it only guarantees total CPU capacity available among hosts in the private cloud.

    Memory

    Sets a quota on memory (in gigabytes) that is available for virtual machines that are deployed on the private cloud. Applied against running virtual machines only. Setting a memory quota does not guarantee contiguous capacity. For example, the private cloud might have available 2 GB of memory on one host and 2 GB of memory on another.

    Storage

    Sets a quota on storage capacity (in gigabytes) that is available to virtual machines that are deployed on the private cloud. For dynamic virtual hard disks, quota calculations are based on maximum size.

    Custom quota (points)

    Sets a quota on virtual machines that are deployed on the private cloud based on total quota points that are assigned to the virtual machines through their virtual machine templates. Quota points are an arbitrary value that can be assigned to a virtual machine template based on the anticipated size of the virtual machines. Custom quotas are provided for backward compatibility with self-service user roles that were created in VMM 2008 R2.

    Virtual machines

    Limits the total number of virtual machines that can be deployed on the private cloud.

  11. On the Capability Profiles page, select the check box next to each virtual machine capability profile that you want to add, and then click Next. Select the capability profiles that match the type of hypervisor platforms that are running in the selected host groups. The built-in capability profiles represent the minimum and maximum values that can be configured for a virtual machine for each supported hypervisor platform.

    For example, select the check box next to Hyper-V, click OK, and then click Next.

    TipTip
    In the Library workspace, you can also create custom capability profiles to limit the resources that are used by virtual machines that are created in the private cloud. To view the settings that are associated with a built-in capability profile or to create a custom capability profile, open the Library workspace, expand Profiles, and then click Capability Profiles. You can view the properties of a capability profile, or on the Home tab, in the Create group, click Create, and then click Capability Profile to create a new one.

  12. On the Summary page, confirm the settings, and then click Finish.

    The Jobs dialog box appears. Make sure that the job has a status of Completed, and then close the dialog box.

  13. To verify that the private cloud was created, in the VMs and Services workspace, expand Clouds.

    The private cloud that you created should appear.

    TipTip
    To view information about used and available resources in the private cloud, in the VMs and Services workspace, expand Clouds, and then click the private cloud. On the Home tab, in the Show group, click Overview. In the Show group, you can also click VMs or Services to view information about virtual machines and services that are deployed to the private cloud.

  14. To verify that the private cloud library was created, open the Library workspace, and then expand Cloud Libraries. A private cloud library is listed that matches the private cloud name. If you expand the private cloud library, depending on what you configured, the read-only library shares are listed together with a Stored Virtual Machines and Services node.

After you create a private cloud, you can assign the private cloud to one or more user roles. To assign the private cloud to an existing user role, or to assign the private cloud and create a user role at the same time, in the VMs and Services workspace, click the private cloud that you want to assign. Then, on the Home tab, in the Cloud group, click Assign Cloud to open the Assign Cloud dialog box. If you select an existing user role, you can modify the properties of the user role. If you select Create a user role and assign this cloud, the Create User Role Wizard opens.
