1. Start with xen kernel. This is a seriesThe root of virtual machine operations. 2. Choose YaST control center> virtualization> install administrative programs and tools. A "bridge" br0 is created. Note: br0 is connected to eth0 by default. If eth0 is the IP address information set manually, br0 will "preemptible"This configuration information causes the eth0 to be reconfigured. 3,Choose YaST control center> virtualization> create virtual machi

Judging the disk usage of DomU under Xen Dom0 is roughly known from xentop: CPU %, MEM %, network, I/O... but for the use of DomU disks, such as: how much inode is used, how much space is left, whether the flash is full or whether the customer should be notified to upgrade the Xen hard disk is insufficient. [root @ Rocky ~] # Xentop use dumpe2fs here to eliminate sorrow for you. Although it is not very accu

The Redhat as 5.5 DVD installation disk has been integrated with xen and KVM! Therefore, the simplest installation method is to install RedHat during RedHat installation. The installation steps are as follows: 1. Close the disk installation; 2. Enter the serial number (if the serial number is not entered, the virtual technology cannot be selected ); 3. After you select virtual technology, xen is install

the virtual CPU is reduced. When the credit of the domain corresponding to the virtual CPU is found to be negative, the virtual CPU is put into the over queue; when all the virtual CPUs are in the over queue, the credit scheduling algorithm proportionally adds the credit of all domains with the weight value originally set for the domain, and add the corresponding virtual CPU to the under queue.The system runs the vcpu with the First Scheduling and under priority. When a processor is idle or the

Xen virtualization uses "semi-virtualization" (para-virtualization), all hardware is only scheduled through the Xen hypervisor, compared to VMware Server and workstations to virtual complete hardware device performance is much better! But has always been used when there is a problem: "Virtual network"! Today, I found the latest BATE package for the Virt-manager (RHEL5 GUI tool for managing virtual machines)

There are a lot of online materials. Here I am writing a purely personal lesson... I am suffering a day, shit! At first, I tried to use the new XL tool stack to configure Bridging networks. As a result, due to lack of experience in network management, after manual bridging, dom0 would not be able to access the network! Later, I tried to use the NAT method. As a result, although dom0 is not affected, domu cannot work, static IP allocation, and Mac won't work... Helpless, return xend, it will auto

Install Linux on Xen-Server 6.5 Virtual MachineCitrix currently supports the release of Linux desktops. However, creating a VM and installing a graphic interface system on XenServer must be specific, to this end, I would like to share with you how to deploy Red Hat Enterprise Linux Server 6.6 In XenServer. 1. Create a VM 1.1 right-click XenCenter and select "New VM" on "XS"1.2 select the corresponding template "Red Hat Enterprise Linux 6 (64-bit)". No

Xen Virtual Machine linux system time settings have not been expected to become a problem, but because of the special requirements in the project, the server needs to be set to China Standard Time. So I studied it. It turns out that after the virtual machine is installed, the time setting part in the Virtual Machine script is generally set to localtime = 0 by default, that is, the time taken from the physical machine is the RTC of the virtual machine.

The company has a new 8-core CPU, which uses xen to virtualize two windows. However, you still cannot balance the CPU pressure through various configurations. Most of them are on the first CPU. Below is the top data Cpu0: 20.6% us, 65.7% Sy, 0.0% Ni, 13.7% ID, 0.0% wa, 0.0% hi, 0.0% Si, 0.0% St Cpu1: 0.0% us, 0.0% Sy, 0.0% Ni, 96.2% ID, 0.0% wa, 0.0% hi, 0.0% Si, 3.8% St Cpu2: 1.0% us, 0.0% Sy, 0.0% Ni, 99.0% ID, 0.0% wa, 0.0% hi, 0.0% Si, 0.0% St

In the case of KVM or Xen virtualization, it is often necessary to use the mirror files (image file), we can start the guest system, and then modify the mirrored file, but this is sometimes more cumbersome, in fact, can be the image file directly mount, There are two ways to do this.method One: Find the starting position of the partition, and use the offset parameter of the Mount command to offset the unwanted before you can get the real partition. th

From xentop, we can see that CPU %, Mem %, network, I/O..., etc. However, for domu disks, such: How much inode is used, how much space is left, whether it is full, and whether the customer should be notified to upgrade the xen Hard Disk These xentop are not enough.
