Linux + Asterisk + MySQL running on VMware ), then it is very difficult to open a client to receive emails and open several browsers to view documents.
Therefore, VPSee intends to donate a SUN server in use to form an Xen Server, and allocate each Honours a virtual system, saving them time and resources for installing their own virtual machines, VPSee has become a free Xen VPS provider :). 16
This article explains the following content: 1. installation steps of xen; 2. how to use xen to build your own virtual machine; 3. problems encountered during installation. 1. check before installation 1) Check whether your host cpu supports virtualization: enter the command cat/proc/cpuinfo | grepflags to check whether there is a pae in the result. If yes, semi-virtualization is supported, check whether vm
At present, Masters in the lab are equipped with one PC and one notebook, but Honours is equipped with only one PC and one machine is inconvenient for project development. multi-system is often used for development, for example, some people are working on projects related to mobile phone VoIP, the mobile client interface should be implemented on Windows platforms, and the VoIP server must use Linux, So virtual machines should be used to virtualize a Linux, it would be slow if all of these were r
XEN was initially a project at Cambridge University. At present, the XEN. ORG community is responsible for its development and maintenance, and it has been greatly developed in the open source community. XEN is a software directly running on the hardware layer. It allows computer hardware to run the operating system of multiple users at the same time. Thanks to s

The server hard disk has been upgraded and the memory is still waiting. The memory is ordered with the hard disk. I don't know why it hasn't arrived yet. I finally found out why the RAID0 test result was abnormal the day before yesterday, A hard disk is faulty ~ There is a problem with the newly purchased unpacked hard disk. Currently, most SUN servers only have 2 GB-8 GB of memory. After the upgrade, the memory size should be 8 GB-32 GB, so that more memory can be allocated to each
The following describes how to install Xen in RedHat and the problems encountered. I. Configure yum source 2. Use yuminstallXX to install kernel-xen and xen-libs. Generally, there is a corresponding package in the installation image. If not, download the rpm package. Package used for this installation: kernel-xen-2.6.1
Xen supports a variety of storage methods, roughly three categories: the most common and direct file storage (Files storage), the local physical hard disk or the LVM storage (physical DEVICES/LVM storage), the more advanced NFS, NAS, GNBD, SAN, AoE, ISCSI network storage (network storage) and so on. These three types of storage media and methods are used in our production environment, each has its own advantages, vpsee bias mixed use, help us understa
Since the RHEL6 version, Redhat is not the original support Xen, instead of the embrace of KVM. Although KVM claims to support the full virtualization of HVM technology, KVM started late after all, far less mature than Xen technology, the system crashes often occur when running multiple instances, and certainly does not exclude the possibility that future KVM will be more efficient. So there are only two wa
A virtual platform is an operating system that supports running Xen;
Virtual Operating System: An operating system that installs and runs on a virtual platform;
For example, if Xen is installed in Slackware, Slackware is a virtual platform and other operating systems can be virtualized through the virtual platform. For example, Debian and Fedora can be virtualized through Slackware ......
1. What is
The key to migrating a VM from KVM to Xen is to replace the original kernel without Xen patches, and then select the appropriate grub (older versions of Xen do not support grub2 ). After completing the preceding two steps, make the image of the KVM virtual machine into an Xen image, and then use the configuration file

Libxc is the name in/xen/tools/. In many addresses, libxenctrl is actually a meaning, but it is different from libxen.. Libxc is a C language library that provides some easy-to-use APIs, allowing your programs to easily communicate with hypervisor.

The Xen virtual machine supports the installation of two types of clients. One is half virtualization, one is full virtualization. The Win2003 system requires installation and operation in a fully virtualized environment.
Hardware environment: DELL R710 CPUs are required to support virtualization (Cat/proc/cpuinfo |grep vmx view), and the BIOS turns on the VT Full virtualization feature. System environment: Physical machine centos5.6 x86_64,
RHEL 5 is a new system with high security and stability ., Xen is an open-source Virtual Machine monitor developed by the University of Cambridge. It intends to run up to 128 fully functional operating systems on a single computer, so the perfect combination of RHEL 5 Xen is now available.
Red Hat adopted Xen server virtualization technology for the first time in
Domu is the guest domain, install a domu basically is a manual work, I have not done a long time almost forgot, recently to test a few systems so picked up, here the process record, the future with the face Roll keyboard on the line ... Domu are divided into two types: Para-virtualization and hardware-virtualization, specific explanations to xen.org to see. The two Domu installation methods are different.
Para-virtualization (class Virtualization):
