xen monitoring

Recently, I tried to install and test xen server6.2. This version is open-source and later. The biggest difference between an unlicensed version and a licensed version is that the licensed version can be installed automatically through xencenter. In short, many features of xencenter comply with my requirements: 1. The free version has basic functions (HA, support for USB forward to VM, templates, and snapshots) 2. xencenter graphical Management

Xen is a beginner. The concept of the communication mechanism between domu and dom0 is unclear. It is summarized as follows for your reference. Find a paper named "xen-based I/O quasi-virtualization driving research" (Hu Leng Fei. (1) I/O shared ring: a fixed shared memory exists between different domains,It is used to transmit I/O requests and responses between domu and dom0.The I/O sharing ring uses produ

Apic-v, APIC virtualization, is an optimization of the Intel CPU for virtual interrupts and APIC virtualization, and using APIC-V can substantially reduce the number of VM exit results due to APIC access, tracking virtual APIC status, and delivering virtual interrupts ( These operations can be done directly in VMX non-root mode without VM Exit. Intel introduced the Apic-v feature in the IVYBRIDGE-EP server CPU. For more information on apic-v, you can refer to the chapter "Chapter APIC Virtualiza

Xen Virtual Machine (Centos6.6) creation and expansion, xencentos6.6 I have not been here for a long time. From this point on, I am going to take a good look at Hadoop's "things ". I am a technical waste, just in accordance with the principle of knowledge sharing, I hope to share my knowledge. If there are any errors in this article, please let me know.

The UUID can be seen in the corresponding Xen center-the virtual machine-the General tab.This article is from the "Enlightened Grocery store" blog, please be sure to

As a VPS service provider we need to ensure that each VPS fair use of the host (server) resources, to avoid a certain VPS due to program death cycle, hang, abuse and other factors "drag" other VPs, if this happens how to temporarily limit the VPS disk IO it? One way to do this is to limit the IO indirectly and imprecise by modifying the CPU weight of each virtual machine. The usual way to limit resources (CPU, memory, IO, etc.) on Linux is to use cgroups, but the Ionice introduced today is much

The allocation of resources on the xen virtual machine has been a headache for the efficiency of the virtual machine for a few days. I have seen all the articles saying that the xen pv performance is good, but we found that this is not the case in actual use, after a long time, I finally found that there was still a configuration problem. With xm top, we can see that the cpu usage of dom0 is basically the s
