xenserver snapshot

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

XenServer installation VM-first Resize and store the ISO image file, xenserveriso We all know that after xenserver is installed, no matter how large your disk is, There is only 4 GB space. Therefore, the operation is to create an LV volume and customize the size. 1. vgdisplay#View the remaining space first [root@XenServer /]# vgdisplay--- Volume group ---VG Na

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

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

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

Citrix XenServer is a value-led, industrial-grade, open-source virtualization platform for managing cloud, server, and desktop virtualization infrastructures. Any organization can download XenServer for free, virtualize the required workloads and automate the management process, enhance it agility, agility, and reduce costs.1.

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

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.

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

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
