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

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

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. XenServer Frame compositionThe Citri

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

Because the company in the computer room hosting server IP is not enough, but also for security considerations, so that a number of virtual nodes can not directly access the Internet, so I xenserver physical nodes through the use of iptables NAT function made a simple implementation [Root@xenserver-cukxsegi ~]# sysctl net.ipv4.ip_forward=1 #开启转发[Root@xenserver-c

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

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

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. After installing the XenServer, visit our server IP, you can see the Xencenter two download links, directly download the MSI to install (this is installed on your computer, the

This section will share the license of how to assign XenServer hosts, note that the activation of Citrix products requires the deployment of license server, so before reading this blog, make sure that license Ser is deployed Ver and the license certificate for importing XenServer. 1.

Labels: Install vmtools on xenserver Virtual Machine Recently, Citrix was deployed in the test environment. Due to resource shortage, a virtual machine was deployed on the HP blade server installed with esxi5.1 and xenserver was installed, however, after the installation, we found that the xenserver virtual machine did not install the vmtools tool.
