Διαχείριση του Citrix XenServer με τον Microsoft System Center VMM 2012
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 modeVirtual 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 packThe 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 canadd 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, entera 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).
Figure 2: Create Run As Account Wizard – General Page
On the Run As Profiles page, click Next (Figure 3).
Figure 3: Create Run As Account Wizard – Run As Profiles Page
On the Summary page, click Finish (Figure 4).
Figure 4: Create Run As Account Wizard – Summary Page
In the Jobs Window, ensure that the Run As account creation is successful, and then close the window (Figure 5).
Figure 5: VMM 2012 Jobs Window – Run As Account
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).
Figure 6: VMM 2012 Console – Fabric Workspace
In the Home bar, click Add Resources, and select Citrix XenServerHosts and Clusters to launch the Add Resource wizard (Figure 7).
Figure 7: VMM 2012 – Add Resources
In the Add Resource wizard, on the Server Settings page, enter thename of the XenServer hosts, the Run As account to connect to the host,
the host group location, and then click Add (Figure 8).
Figure 8: VMM 2012 – Add Resource Wizard
After adding the XenServer host, click Next. On the Summary page, click Finish (Figure 9).
Figure 9: Add Resource Wizard – Summary Page
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, VMM2012 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).
Figure 11: VMM 2012 Console – Fabric Workspace with XenServer Host
In the Hosts Pane, right-click the XenServer host, and then select Properties (Figure 12).
Figure 12: VMM 2012 Console – Server Properties Selection
In the XenServer host properties, select Hardware, and then select the Network Adapter (Figure 13).
Figure 13: VMM 2012 Console – Network Adapter Properties
Under Logical Network Connectivity, select the logical network thatshould be associated with the network adapter, and then click OK in the
Warning box (Figure 14).
Figure 14: VMM 2012 Console – VLAN Warning
Click OK to close the XenServer host properties page. In the Hosts pane, right-click the XenServer host, and then select View Networking (Figure 15).
Figure 15: VMM 2012 Console – View Networking
In the Networking Diagram window, verify that the XenServer hostnetwork adapter is connected to the required virtual network (Figure
16).

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).
Figure 17: VMs and Services Workspace
In the Home bar, click Create Virtual Machine (Figure 18) and thenselect Create Virtual Machine from the menu to launch the New Virtual
Machine wizard.

In the New Virtual Machine wizard, on the Select Source page, selectCreate The New Virtual Machine With A Blank Virtual Hard Disk, and then
click Next (Figure 19).
Figure 19: New Virtual Machine Wizard – Select Source Page
On the Virtual Machine Identity page, enter a name for the virtual machine, and then select Next (Figure 20).
Figure 20: New Virtual Machine Wizard – Virtual Machine Identity Page
On the Configure Hardware page, select the Compatibility option inthe 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.

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.
