When troubleshooting XenServer issues, it is important to have an understanding of the XenServer Architecture. Although you can be using XenCenter to work with XenServer hosts, you can also use ssh to connect to Dom0 which is the VM with special privileges which must be running on Each XenServer host. There are a variety of ways to talk to XenServer (various consoles, cloud-management software, PowerShell etc.), in the background we are usually talking directly to the XAPI toolstack. On the Dom0 console, we can use xe commands in order to use the Xen API. We are normally using standard Linux command and tools to talk directly to the Xen hypervisor and directly to the hardware.When XAPI commands are issued, standard Linux configuration files are issued in Dom0 and also through XAPI, device drivers are also called to talk directly to the storage.Generally speaking, weather you are taking about a storage area network or local storage (i.e. the local disk on the XenServer itself), there are 2 types of storage – thin provisioned or thick provisioned.A good analogy of thin provisioned storage is a file divider – it may start with no files in it but as you add more and more files, it starts to expand – its exactly the same in the virtual world – The danger is that you can over-allocate your storageThick provisioning is more analogous to box files (as illustrated in the diagram to the far right). A box file will always take up a certain amount of space regardless of weather there is 1 file in there or 100 file – in the virtual world, its very similar creating a 40GB disk – there will always be 40 GB reserved for the contents even if you add files that are only taking up a fraction of the entire size of the disk. Depending on the type of storage you use, it will be thin or thick.If you want to create a point-in-time backup of a virtual machine, a snapshot should be created on the xe command line or within XenCenter.Our snapshot technology enables backup vendors to interface directly with XenServer allowing in-guest full and incremental backups of VMs.Snapshots are available on all storage platforms through LVHD implementation. Creating and deleting snapshots differs quite substantially depending on weather you are using thin or thick provisioned storage.Assume you created a virtual disk (along with your VM) of 40GB and use up 20GB of storage space for the operating system and various files (represented by ‘A’ in the above diagram)Further assume that thin provisioning is in use.Once we take a snapshot, the following happens.Disk A is deflated to 20GB and will become read-onlyA new disk for writing the data to will be created (initially close to 0 Bytes in size as its thinly provisioned). It only holds VHD header information – Lets call it 0 bytes for simplicity.A snapshot VHD will also be created which will also be close to 0 Bytes in size)The total size of the disk after taking the snapshot is c. 20+0+0 = c. 20GB Assume you created a virtual disk (along with your VM) of 40GB and use up 20GB of storage space for the operating system and various files (represented by ‘A’ in the above diagram)Now assume that thick provisioning is in use (i.e. you are using Fiber Channel, iSCSI or local LVHD (thick provisioning)Once we take a snapshot, the following happens; Disk A is deflated to 20GB and will become read-only A new disk for writing the data to will be created and inflated to 40GBA snapshot VHD will also be created which will be close to 0 Bytes in size , i.e. Just containing VHD header informationThe total size of the disk after taking the snapshot is c. 20+40+0 = c. 60GB If you delete snapshots (e.g. if you delete the VHDs labled ‘C’ and ‘E’ in the diagram to the top left), we should be able to coalesce all of the information from disks B and D back to A if writes have been made to both. Note that the longer the chain, the slower this process is going to be.The command vhd-util scan –m ‘V*’ –l <SR_VG> -p will show a parent VDI on the left and the child VDIs underneathThe vhd-util repair command can fix VHD header information as VHD files contain a second copy of the header information as a backup so there is a good possibility that corrupted header information can be fixed using the vhd-util repair command.The amount of disk space taken by snapshots depends on the size of the VDI and the amount of shared data. The key components of Xentools are;XEN – initiaizes and owns the hypercall interfaceXENFILT – uplugs emulated devicesXENBUS – Creates main PV interfaces (e.g. EVTCHN, XENSTORE etc.) and enumerates all PV classes (e.g. VIF, VBD etc.)XENVIF – Network class driver: enumerates VIFsXENNET – Network interface driver / NDIS 6.0 miniportXENVBD – Storage class driver (enumerates VBDs) / Storeport miniport (the scsi filter driver is no longer needed and the storeport miniport driver is much faster)XENIFACE – WMI API to XENSTORE For the XenServer 6.1 product the xentools package has changed significantly.To support Windows XP and Windows Server 2003, the legacy drivers and install package continues to be supported and maintained (i.e. inclusion of bug fixes).For Windows XP and Windows Server 2003, the installer app is now called xenlegacy. The familiar xensetup.exe meta-installer is still available. Due to the new WDK (Windows Driver Model) for Windows 8, the driver set had to be split between the newer drivers (Windows Vista and higher) and the older ones for Windows XP and Windows 2003.In order to make things simpler, a single install wizard is used.Issues Resolved In Hotfix XS61E009 and XS61E0101. Virtual Machines (VMs) with out of date XenServer Tools, may not be flagged as "out of date" in XenCenter. Hotfix XS61E009 resolves this issue and enables customers to be notified in XenCenter when new XenServer Tools are available.2. Booting a Citrix Provisioning Services (PVS) target device using a Boot Device Manager (BDM) image can take an extended time to complete. Hotfix XS61E009 resolves this issue.3. Customers using XenServer Platinum Edition to license Citrix Provisioning Services (PVS) may find that one PVS license per VM is checked out, rather than one PVS license per XenServer host. This may lead to a shortage of PVS licenses and an inability to provision VMs. Hotfix XS61E010 along with CTX135672 - Hotfix CPVS61016 (Version 6.1.16) - For Citrix Provisioning Services 6.1 - English resolves this issue.4. Attempts to shut down Microsoft Windows Vista and later VMs can cause intermittent blue screen errors, with a "STOP: 0x0000009f..." error message. Hotfix XS61E010 resolves this issue.5. Adding more than eight NICs to Microsoft Windows Vista and later VMs, using the xe CLI can lead to a blue screen error on reboot. Hotfix XS61E010 resolves this issue.6. Copying data to a Microsoft Windows 2003 VM can cause the VMs to hang and lead to a grey screen error. Hotfix XS61E010 resolves this issue.7. When Dynamic Memory Control (DMC) is enabled, attempts to migrate Microsoft Windows XP and later VMs using XenMotion can cause the VMs to hang and lead to blue screen error. Hotfix XS61E010 resolves this issue.8. When the Citrix Xen Guest Agent service is running, Cut and Paste will not work between a XenDesktop virtual desktop and the endpoint device. Hotfix XS61E010 resolves this issue.Each of the issues below have also been resolved In Hotfix XS61E009 and XS61E0101. When the Citrix Xen Guest Agent service is running, Cut and Paste will not work between a XenDesktop virtual desktop and the endpoint device. Hotfix XS61E010 resolves this issue.2. Microsoft Windows XP and later VMs may hang during the boot process and may have to be forced to reboot. Hotfix XS61E010 resolves this issue.3. Attempting to install or upgrade the XenServer Tools on Microsoft Windows Vista and later VMs, which do not have access to a paravirtualized or an emulated network device can cause the installation process to hang. Hotfix XS61E010 resolves this issue.4. Manually installing the Legacy XenServer Tools without changing the device_id to 0001 can result in a "STOP: 0x0000007B..."error when rebooting a Windows VM. After installing Hotfix XS61E010, customers will not be able to manually install the Legacy XenServer Hotfix XS61E010 Tools by running xenlegacy.exe. When customers start the XenServer Tools installation process, the installwizard.msi launches automatically.5. Microsoft Volume Shadow Copy Services (VSS) (required for third party backup solutions) was unavailable on Microsoft Windows Server 2008 in the original version of XenServer 6.1.0. After installing Hotfix XS61E010, XenServer 6.1.0 customers will be able to take quiesced snapshots on Microsoft Windows Server 2003 and Windows Server 2008 VMs. For Windows Server 2008 R2, see the guidance that appears earlier in this section.Some workarounds have been followed in relation to known issues (as discussed) – It is very important that the guidance provided in http://support.citrix.com/article/CTX135099is followed in these cases. This article gives a comprehensive overview on how to troubleshoot XenServer tools in general and particularly in relation to XenServer 6.1A really key advantage of the Windows update model is that deployment of bug fixes and new features can now be delivered automatically and independently of any XenServer release.

Presenters Media, 2013 (All rights reserved)When using XenDesktop 7.0 with a hosted shared desktop or app publishing scenario you will have to install a vda-agent onto the Windows Server to be able to publish apps or shared desktops.
During the install there is no check for existence of a RDS licensing server. In theory you can use the 120 day evaluation period to test with. But what when you’re done testing and want to make it permanent by adding RDS licensing?
Using Windows Server 2008 R2 or earlier is pretty straightforward. Because the Windows Server 2008 R2 RDS licensing in my case already existed, even with older Windows Terminal services licensing, there was no need for a evaluation period.
Windows Server 2012 RDS is another story, this gives some extra headaches. Because we’re using Citrix as a connection broker we don’t have a complete Microsoft Remote Desktop Services Deployment in place.
First we need to add a RD licensing server role because this is the first Windows Server 2012 RDSH in the environment. So far so good.
Second we need to activate the license server, this succeeded too.
Next we need to assign the license server to the RDSH server and make sure the right licensing mode is used (we use PerUser licensing).
This is where the problems arise. Microsoft assumes you use a complete Remote Desktop Services deployment including a RD broker. Therefor you cannot set the properties of a RDSH via the GUI (with Server Manager) or through command line (with PowerShell) as shown in the screenshots below.
How to solve it?
To set the correct license server and the mode it is operating in, we need to use a (local) group policy or change it directly in the registry.
Citrix License Server Setup
The group policy setting the Remote Desktop licensing mode is located in:
Computer ConfigurationPoliciesAdministrative TemplatesWindows ComponentsRemote Desktop ServicesRemote Desktop Session HostLicensing
This can be configured by using either the Local Group Policy editor or the Group Policy Management console.

The other way is to manually change it on the RDSH using the following registry keys:
HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows NTTerminal Services
Install Citrix License Server
| LicenseServers | <license server> |
| LicensingMode | 2 for PerDevice; 4 for PerUser |

After changing these settings, reboot your RD Session Host and you will see RD licensing is now in place and working!
