System RequirementsXenServer requires at least two separate x86 physical computers: one to use as a XenServer host and another to run XenCenter applications.The XenServer host computer is completely dedicated to running the XenServer that hosts the VM and is not used to run other applications. The computer running Xencenter can be any universal Windows computer t
Last night encountered a very depressing problem, XenServer machine XAPI can not start, all XE commands can not be executed, the only way to access only SSH, the problem is that there are many virtual machines on this machine is running, try a lot of methods have no effect, The only solution is to rebuild the environment without affecting the production after daybreak.Idea: Considering the use of local storage, the host should be able to recognize the
Last year, wrote an article about XenServer virtual machine suspended animation problem, http://kaiqian.blog.51cto.com/236001/1625411 interested students can see this article.Some time ago, I was asked to reflect on this problem, so the continuation of the idea did a further troubleshooting.Phenomenon: A xenserver on the normal operation of the process, a number of virtual machines into the state of the bri
The agent can provide feedback on the performance and running status to the system administrator.Although installing the tool is simple, you must note that you must restart the virtual machine after installation, as is true for any hypervisor.The reason for restarting the host is that the disk controller drivers and some network drivers cannot be hot removed or replaced. Restart the VM to bring the host back to initialization.For a virtual machine to install
Just one of the problems I had before, today to demonstrate again to restore the problem, to see how to achieve recovery.

It is necessary to install XenServer on a virtual machine on windows 8, whether it is a hypervisor or a virtual machine operating system (OS ). With this tool, you can find the drivers, disk controller drivers, and a management agent that support virtual network devices to provide better integration and program management. The agent can provide feedback on the performance and running status to the system administrator. Although installing the tool is
In the previous article, we introduced the XenServer Bridge network stack pattern, and now in this document we will cover another open-source network stack pattern supported by XenServer: Open vswitch. XenServer now the version of the deployment is installed by default in open Vswitch mode, if we do not need to do LACP or bind more network cards and the use of di
There is a Xenserver node in the data center. The RAID 5 made of six disks has an alarm today. It is estimated that the disk data is inconsistent. At that time, I forgot to prepare a hot spare disk. So before restarting, back up the node and restart it to verify the disk.First, check which nodes are available.[Root @ xenserver-DS-TestServer04 mnt] # xe vm-listUuid (RO): 0555a7e5-eba4-aaae-2caf-bbb4b53724aaN

To modify the virtual machine disk sizeModify the storage disk size
Start a virtual machine
Modify Partition sizeFdisk/dev/xvdaThe number of cylinders for this disk was set to 5221.There is nothing wrong with the, but this is larger than 1024,And could in certain setups cause problems with:1) software that runs at boot time (e.g., old versions of LILO)2) booting and partitioning software from the other OSs(e.g., DOS fdisk, O
To start installing the operating system on the VM, although XenServer already contains multiple templates, such as redhat as 4+5, CentOS, SuSE, Oracle Enterprise Linux, and so on, there is no need to download the original installation discs at installation time; If you are not in the list, such as redhat as 3, you must install it using the CD-ROM method. This shows you how to install the required operating system in ISO format when adding VMS.
First
Instead of developing a dedicated network stack pattern on the web itself, XenServer uses existing network stack patterns for integration. There are two main types of XenServer network stacks: Bridge and Openvswitch mode. Bridge is a Linux-system technology, and Openvswitch is an open-source Virtual Switch software. In this article I would like to talk about bridge stack mode.Bridge Chinese is called the Br
Eject any loaded DVD media, like Xs-tools.iso, so the virtual DVD drive is empty.
Snapshot VM before starting so you can roll back in case of problems.
Added Registry Key so the MSIServer (handles MSI Install/uninstall) can run in Safe Mode using command:REG ADD "Hklm\system\currentcontrolset\control\safeboot\minimal\msiserver"/ve/t reg_sz/f/d "Service"
Run msconfig and set computer to boot on Safe Mode with the Minimal option.
Reboot computer.
When the Windows starts in Safe Mode

So the question is, how to build an ISO Image Library on XenServer.

Today's XenServer also has a snapshot technology, if you are doing some dangerous operations, you can take a snapshot, so that even if there is a problem, you can quickly recover. Snapshots can save the state of a virtual machine at a point in time, and can be recovered whenever an error occurs.
But if you forget to take snapshots, or if you have trouble making snapshots every time, or if some virtual machines need to be backed up every day, then sna
When the iron is hot, let's play xenserver. Yesterday Zhao Jong with the computer room provided KVM to the server installed XenServer, today we come to play more interesting: open chicken.
