Nutanix SCVMM Fast Clones Plug-in

Hi Everyone…I love to show off the cool Microsoft integrations that Nutanix has and most recently Nutanix released System Center Virtual Machine Manager (SCVMM) 2012 R2 Fast Clones plug-in.

With NOS 4.1.3, Nutanix has released a Fast Clone plugin for SCVMM.  The plug-in has the ability to provide space efficient, low impact clones from SCVMM and quickly. The plugin is a wrapper around Nutanix powershell commands for Fast Cones. The plugin does need proper access rights to the Hyper-V hosts and SCVMM and already should be setup for most environments that have Nutanix with Hyper-V deployed.  You will need to install the plugin on the SCVMM host along with the Nutanix powershell command-lets.

Once you have the SCVMM Fast Clones plug-in installed, you can start creating Fast Clones right away. Installation is quick and easy and creating clones is just as easy as shown below.

To create VM clones using the Nutanix Fast Clones wizard, follow the below steps:

  1. Start the SCVMM
  2. Navigate to the Nutanix hosts.
  3. Select a host and then select the VM to be cloned.
  4. To invoke the wizard, do one of the following: Click the “Nutanix Fast Clone” button on the top menu-bar. Right-click the target VM and select “Nutanix Fast Clone” from the pop-up context menu:
    fastclones2 Fast Clones
  5. In the Introduction screen, read the instructions and then click the “Next” button.  NOTE: On start of the wizard, it makes a connection to the VMM to be able to communicate with it to run SCVMM PowerShell cmdlets to gather information about the selected VM.
    fastclones1 Fast Clones
  6. The “Identity” screen is displayed. The “Source VM Name” and “Source VM Host Name” is prepopulated, enter the following information and then click the “Next” button:
    1. Clone Type: Click the “Clone One Virtual Machine” radio button and enter a name for the clone when creating a single clone or click the “Clone Multiple Virtual Machines” radio button and enter the following information:
      1. VM Prefix Name: This is the root part of the new VM name.
      2. Beginning Suffix: a number to start the numbering of the new VMs
      3. Number of Clones: a number between 1 and 100.
        fastclones3 Fast Clones
  7. In the Authentication screen, enter the Prism and VMM Service Account user names and passwords in the appropriate fields, and then click the “Next” button.
    fastclones4 Fast Clones
  8. In the “Select Path” screen, select the destination path and then click the “Next” button. Leave the default path “as is” or change it to a new path as needed by clicking the “Change the default path” box. Click the Browse button to select a destination path for the clone VMs. This is the path where virtual machine configuration files will be stored. The path must be on the same Nutanix SMB share as the VM configuration file.
    fastclones5 Fast Clones
  9. In the “Add Properties” screen, click the appropriate radio button to either power on or not power on the VMs after cloning and then click the “Next” button.
    fastclones6 Fast Clones
  10. In the Summary screen below, review (confirm) the settings are correct.
    fastclones7 Fast Clones
    Clicking the “View Script” button displays the script to be executed:
    fastclones9 Fast Clones
    Clicking the “Enable Verbose Messages” displays detailed log messages as the VMs are being created.
  11. When the settings are correct, click the “Create” button to create the cloned VM(s). An hour glass is displayed and progress messages are displayed.
  12. After the clones are created, click the Finish button to close the wizard and you just created VM’s at lighting speed.fastclones10 Fast Clones

If you want to check out Fast Clones for your environment, you can download Fast Clones from the Nutanix Portal at https://portal.nutanix.com.

Below is a demo video shows traditional cloning vs Fast Clones that my buddy @mcghem created.  It shows the awesome benefit of Fast Clones.

Nutanix SCOM Management Pack – Monitor Your Nutanix Infrastructure

As a Microsoft Evangelist at Nutanix, I am always asked….”How would you monitor your Nutanix Infrastructure and can I use System Center suite. And my answer always is, “YES, with SCOM”….What is SCOM you ask?
SysCnt-OprtnsMgr_h_rgb_2 Nutanix SCOM Management Pack System Center Operations Manager (SCOM) is designed to be a monitoring tool for the datacenter. Think of a datacenter with multiple vendors representing multiple software and hardware products. Consequently, SCOM was developed to be extensible using the concept of management packs. Vendors typically develop one or more management packs for every product they want plugged into SCOM.

To facilitate these management packs, SCOM supports standard discovery and data collection mechanisms like SNMP, but also affords vendors the flexibility of native API driven data collection.  Nutanix provides management packs that support using the Microsoft System Center Operations Manager (SCOM) to monitor a Nutanix cluster.

Nutanix SCOM Management Pack

The management packs collect information about software (cluster) elements through SNMP and hardware elements through ipmiutil (Intelligent Platform Management Interface Utility) and REST API calls and then package that information for SCOM to digest. Note: The Hardware Elements Management Pack leverages the ipmiutil program to gather information from Nutanix block for Fans, Power Supply and Temperature.
SCOM01 Nutanix SCOM Management Pack

Nutanix provides two management packs:

  • Cluster Management Pack – This management pack collects information about software elements of a cluster including Controller VMs, storage pools, and containers.
  • Hardware Management Pack – This management pack collects information about hardware elements of a cluster including fans, power supplies, disks, and nodes.

Installing and configuring the management packs involves the following simple steps:

  1. Install and configure SCOM on the Windows server system (if not installed) (will blog a post soon on this topic)
  2. Uninstall existing Nutanix management packs (if present)
  3. Open the IPMI-related ports (if not open). IPMI access is required for the hardware management pack
  4. Install the Nutanix management packs
  5. Configure the management packs using the SCOM discovery and template wizards

Also, I check out this great video produced by pal @mcghem . He shows a great demo of the SCOM management pack…Kudo’s Mike….also, check out his blog.
