Analysis of 100xd project problems

1. the Citrix host prompt is displayed when you connect to the database in the DDC Initialization Configuration.

Services are unavailable and cannot correctly configure DDC

This problem occurs because a large amount of storage is added to the DDC configuration, resulting in a Citrix host service interruption. You can add a small amount of storage in the DDC configuration, then add the remaining storage in the host configuration to solve the problem.

2. The client can use IE to connect to the desktop or the pluger client plug-in to connect. During the test, we found that the connection method of the new version of receiver4.1 needs to Use https. Do you need to use HTTPS to log on to the interface through HTTP?

Through analysis, after the receiver3.4 version, the client uses the plug-in to log on using HTTPS by default. Receiver3.3 and receiver3.2 can be connected through HTTP. Install and test on a physical machine. With receive3.2, the client can use IE to log on to the virtual desktop and use the javaser plug-in. For some tests, we recommend that you use receiver3.2 as the client plug-in installation version. At the same time, we also want to conduct the receiver3.3 version and observe the effect.

3. the Citrix dialog box is displayed when you log on to the virtual desktop for the first time. On the virtual desktop, you can control the preference resolution and access to the desktop. Currently, security needs to control users' preferences. the dialog box cannot be displayed.

1. Based on the KB provided by Citrix technical support, test the disable Preference Policy on win7. The policy can be enabled normally and the access to the local disk by the virtual desktop can be controlled. However, the user's access permission option is not found to be locked in the client's preferences. Communicate with Citrix technical support: confirm the preference content by importing the registry and ADM template to control the user's virtual desktop access to local disk data. However, the user's selection in the virtual desktop preferences cannot be locked, which is a bug in the Citrix Explorer plug-in. To forcibly control users' preferences, you can only delete the Citrix toolbar to prevent users from accessing preferences. However, we do not recommend that you do this. The toolbar also contains very useful options for users, such as homepage and window mode.

The hdx policy is used to control the access to local disk data.

4. log on to the released virtual desktop and view the CPU. The following problems are found: 4 CPU is allocated to the virtual desktop in the configuration, but 2 CPU is displayed in the published desktop properties, check that the number of CPUs in resource manager is also 2

After comparison, it was found that the Device Manager in the virtual desktop confirmed that 4 CPU is allocated, but the virtual desktop only identified 2 CPU. After troubleshooting, this problem is related to the Citrix xenserver mechanism: the vcpu allocated by xenserver to virtual machines is presented to the upper-layer virtual machines in the form of socket. As a result, a maximum of two vcpus can be allocated to the virtual machines through xencenter, even if multiple vcpus are allocated, the system cannot recognize it either, because Windows 7 and XP support up to two sockets. To solve this problem, you need to manually adjust the Platform Mode settings of the Virtual Machine CPU in xenserver. On the master node in the pool, set the cores-per-socket for the template or the platform parameter of the virtual machine.

Xe VM-param-set platform: Cores-per-socket = <some count> UUID = <target vm uuid>

By changing commands in xenserver, the number of CPUs that can be recognized and utilized in VDA and virtual desktops is 4 allocated as required.

5. Check the storage and find that the storage uses the simplified backup mode.

For Citrix, there are two types of storage: file-based vhd: in this case, the image of the VM will be saved on the SR or shared NFS storage in the simplified vhd format, that is, how much storage is used and how much storage is used. The other is based on LVM-based vhd. By default, when xenserver is connected to an optical fiber, the local storage of iSCSI or SAS is stored in the future as the standby mode, that is, how much storage is allocated, storage space. The environment of Ping An bank is the nfs nas storage of netapp. Therefore, the simplified backup mode is used to view the storage status.

6. The testing desktop background released through VDA is black.

You can use personalized settings to change the desktop background to blue sky and white clouds. It is determined that the problem may be caused by the use of Remote Desktop when testing and installing software, and the background setting of Remote Desktop is disabled.

VII. Optimal Lun Division

A Lun with less than 30 VMS, the closer it is to this value, the better
