Σκοπός του συγκεκριμένου άρθρου, το οποίο θεώρησα σωστό να μην προχωρήσω σε μετάφρασή του είναι να πάρουμε μια ενδελεχή εικόνα των τεχνολογιών τις οποίες η Microsoft πρόκειται να διαθέσει σε πολύ σύντομο χρονικό διάστημα στην παγκόσμια αγορά πληροφορικής οι οποίες τολμώ να πω ότι θα προκαλέσουν επανάσταση. Και τούτο διότι πολύ απλά, η Microsoft καινοτομεί ξεφεύγοντας από τα στενά προϊοντικά της πλαίσια δίνοντας εκείνα τα εργαλεία τα οποία μας επιτρέπουν να διαχειριστούμε εγκαταστάσεις private και public cloud οι οποίες χρησιμοποιούν συνδυσμό τεχνολογιών virtualization όπως Microsoft Hyper-V, VMWare VSphere, Citrix XenServer κ.τ.λ..

Μια τέτοια περίπτωση είναι και η παρακάτω όπου με τον  

System Center Virtual Machine Manager 2012 (VMM 2012) μπορούμε να διαχειριστούμε περιβάλλοντα Citrix XenServer.

 

In System Center Virtual Machine Manager 2008 R2

(VMM 2008 R2), Microsoft provides a single management console that

supports multiple virtualization platforms including Hyper-V and VMware

ESX/ESXi. With System Center Virtual Machine Manager 2012 (VMM 2012),

Citrix XenServer is also supported. VMM 2012 allows the use of standard

processes and procedures to perform daily management operations across

the supported virtualization platforms, including:

Host Features

Host discovery and management (clusters and pools)

Host power optimization

Host maintenance mode

Virtual Machine Features

Creation, deployment, and management of virtual machines

Creation, deployment, and management of VMM services

Placement of virtual machines based on host ratings

Load balancing

Storage of resources in VMM library

Conversion of virtual machines to Hyper-V

 

VMM 2012 also enables using XenServer host resources, along with

Hyper-V and VMware hosts, to create heterogeneous private clouds managed

using a single graphical user interface (GUI) and command-line

interface (CLI).

Citrix XenServer Host Requirements

In order to be managed through VMM 2012, a Citrix XenServer must meet the following requirements:

XenServer 5.6 Feature Pack 1

XenServer SCVMM Integration Suite supplemental pack

The SCVMM Integration Suite supplemental pack

is installed during the XenServer installation using a SCVMM Beta

Integration CD, or post-installation through the CLI using a SCVMM Beta

Integration ISO. VMM 2012 does not require an agent deployment to

XenServer hosts.

XenServer hosts and XenServer pools can be added and managed using

VMM 2012. However, a XenServer host must be installed before adding it

to VMM 2012. Also, XenServer pools must be created and configured in

Citrix XenCenter.

Configuring VMM 2012 to Manage Citrix XenServer

Before you can

add a XenServer host to VMM 2012, you should create a Run As account to

define account credentials that VMM 2012 can use to access a XenServer

host. Although it is generally recommended that you perform this

procedure before adding the XenServer host, you can also create a Run As

account during the process to add a XenServer host.

Adding a Run As Account in VMM 2012

Launch the VMM Console and then select the Settings workspace.

In the Settings pane, select Run As Accounts (Figure 1).

Figure 1: VMM Console – Settings Workspace

In the Home bar, click Create Run As Account to launch the Create Run As Account wizard.

In the Create Run As Account wizard, on the General page, enter

a name for the new Run As account, then select the Host Computer option

from the Category pull-down menu, then enter the account credentials

(host or Active Directory account depending how the XenServer host is

configured) in the username and password fields, and then select Next.

(Figure 2).

On the Run As Profiles page, click Next (Figure 3).

On the Summary page, click Finish (Figure 4).

In the Jobs Window, ensure that the Run As account creation is successful, and then close the window (Figure 5).

Adding a XenServer Host in VMM 2012

After creating a Run As account, you can add a XenServer host to VMM 2012 from within the Fabric workspace in the VMM Console.

In the VMM 2012 Console, select the Fabric workspace (Figure 6).

 

image0061315857155586.jpg

Figure 6: VMM 2012 Console – Fabric Workspace

In the Home bar, click Add Resources, and select Citrix XenServer

Hosts and Clusters to launch the Add Resource wizard (Figure 7).

 

image0071315857177007.png

Figure 7: VMM 2012 – Add Resources

In the Add Resource wizard, on the Server Settings page, enter the

name of the XenServer hosts, the Run As account to connect to the host,

the host group location, and then click Add (Figure 8).

After adding the XenServer host, click Next.

On the Summary page, click Finish (Figure 9).

In the Jobs window, verify that the host is successfully added (Figure 10).

Figure 10: Jobs Window – Add XenServer Host

In this example, because the XenServer host belongs to a pool, VMM

2012 created a host cluster named XSPool in the host group, and based it

on the name of the pool in XenCenter.

Configuring Networking for a XenServer Host in VMM 2012

Before using VMM 2012 to create a virtual machine on a XenServer host

that can connect to a virtual network, you must configure the network

properties on the host. Using VMM 2012, you can associate XenServer host

physical network adapters to logical networks.

In the VMM 2012 Console, select the Fabric workspace (Figure 11).

Under Logical Network Connectivity, select the logical network that

should be associated with the network adapter, and then click OK in the

Warning box (Figure 14).

Creating and deploying a Virtual Machine to XenServer using VMM 2012

Creating and deploying a new virtual machine to a XenServer host using VMM 2012 is performed in the VMs and Services workspace.

In the VMM 2012 Console, select the VMs and Services workspace (Figure 17).

In the Home bar, click Create Virtual Machine (Figure 18) and then

select Create Virtual Machine from the menu to launch the New Virtual

Machine wizard.

On the Configure Hardware page, select the Compatibility option in

the left pane, select the Xen capability profile in the right pane

(Figure 21), adjust the resource configuration as required, and then

click Next. The Xen capability profile is a pre-configured profile that

defines resource minimum and maximum values that can be configured.

Customized capability profiles are created in the Library workspace.

Additional VMM 2012 Management Features for Citrix XenServer

VMM

2012 supports the ability to manage many additional facets of XenServer

operations. The following table contains a brief overview of other

major management features, but is not all inclusive. For more

information, review the Citrix XenServer management information on the Microsoft Technet site.  


Command Line Management


The VMM command shell supports XenServer hosts management


VMM Service


A VMM service – a set of virtual machines defined using a service
template that captures configuration, networking, load balancing, and
deployment settings for a single release of a service
– can be deployed to XenServer hosts


Live Migration


VMM 2012 supports XenMotion between XenServer hosts in a managed pool


Maintenance Mode


VMM 2012 supports placing a managed XenServer host in and out of maintenance mode


Library


VMM 2012 support storing XenServer virtual machines, disks, and VMM templates in the VMM library


VMM Templates


VMM templates supports XenServer hosts, with these restrictions:


·         Supports generalization and customization for Windows-based virtual machines only


·         Supports manual installation of XenServer Tools


·         Supports only original disk images without modifications


Conversion


VMM 2012 supports conversion of XenServer Windows-based virtual
machines to Hyper-V virtual machines using the P2V conversion process,
without removing XenServer Tools

Conclusion

While System Center VMM 2008 R2 provides the ability to manage

virtualization environments that include both Microsoft and VMware

virtualization components, Citrix XenServer is supported with VMM 2012.

Because of Windows PowerShell integration with VMM 2012, administrators

also have the choice to manage XenServer hosts either through the VMM

2012 console, or using the VMM command line. With VMM 2012, Microsoft

provides a solid, single pane interface that allows organizations to

deploy small scale or private clouds that support the top virtualization

platforms on the market.
