解决VMware vSphere Client无法连接ESXi虚拟主机方法1 一般情况下重启services.sh就可以解决（或图形界面下restart management agent）services.sh restart2 若重启services.sh报错且仍然无法连接watchdog-hostd:PID file /var/run/vmware/watchdog-hostd.PID not foundwatchdog-hostd:Unable to terminate watchdog:Can't find process/etc/init.d/hostd:kill:48:(84046924)-No such process这个报错是由于启动/关闭hostd服务器引起的。说明hostd进程没kill到。（原因运行一下/etc/init.d/hostd start or stop就知道）ps | grep hostd 你会看到123456233  789789789  hostd456123358  789789789  hostd123            789789789  hostd123458985  789789789  hostd........说明有hostd进程那运行/etc/init.d/hostd  stop再运行ps | grep hostd 123456233  789789789  hostd456123358  789789789  hostd123            789789789  hostd123458985  789789789  hostd........说...

ESXI5 如何查看VM的VNC端口与密码ESXI5 如果给VM配置的VNC端口与密码，那么VM运行时，不能在vcenter或是vshpere client 中查看对应的VNC端口与密码。这时我们可以打开VM esxi 系统的SSH服务，然后使用SSH远程到服务器。比如VM名称是win2003 ,在SSH 中查看对应的VM配置文件#：cat  /vmfs/volumes/datastore2/win2003/win2003.vmx查看如下内容：

How to Reinstall XenServer and Preserve Virtual Machines on a Local DiskDocument ID: CTX120962    /   Created On: 2009-6-2    /   Updated On: 2010-2-4Average Rating: (2 ratings) View products this document applies to SummaryThis document explains how to reinstall a XenServer host and preserve VMs on the local storage.Requirements• Basic XenServer knowledge• Basic LVM knowledge• XenServer host (4.1 or 5.0) with two local hard drivesBackgroundSometimes, reinstallation of XenServer is required to obtain a clean system state or to recover from a serious failure (such as database file corruption), where Virtual Machines (VMs) residing on local storage must be preserved and recovered within a reasonable amount of time.ProcedureTo achieve the above goal, perform the following steps:1. If possible, collect VM metadata with the command below and store it offline (such as on a USB drive). This step requires a working XAPI stack.x...

XenServer6.0不能自动启动VM的解决办法  从XenServer 5.6升级到6.0后发现不允许VM自动启动，每次启动或者重启server都要手动启动VM，非常麻烦。该怎么办呢？XenServer本身就是Linux，利用Linux开机自启动的特性，可以完美解决这个问题，以后就不用手动启动VM啦。添加以下内容到linux的开机自启动脚本文件/etc/rc.localsleep 30for vmname in \vm-idc \WebServer209 \Windows_7_32bit_70 \Windows_7_32bit_71 \Windows_7_32bit_72 \Windows_7_32bit_73 \Windows_7_32bit_74 \Windows_7_32bit_75 \Windows_7_32bit_76 \Windows_7_32bit_77 \Windows_7_32bit_78 \Windows_7_32bit_79 \Windows_7_32bit_80 \Windows_7_32bit_81 \Windows_7_32bit_82 ;doxe vm-start vm=$vmnamedonevmname为你的XenServer中的VMxe vm-start vm=$vmname手动启动vm的控制台命令。其实，手动跟自动都是一样的，关键你是怎么利用的，^_^。sleep 30这一句一定不能少哦。这一句折腾了我不少时间了。如果没有这一句，vm是自启动不了的。至于为什么，应该不难明白了吧。

在Xen Server上安装iftop监控VM的流量在GUN/Linux系统中，我们可以使用top查看系统资源、进程、内存占用等信息。查看网络状态可以使用netstat、nmap等工具。若要查看实时的网络流量，监控TCP/IP连接等，则可以使用iftop。为了更好的管理Xen Server服务器，我们可以给Xen Server 安装上iftop来监控各客户机IP的流量。一般情况下，我们需要到iftop官网下载最新的源码包来进行编译安装。但是默认情况下，Xen Server是没有编译环境，比如：make、gcc、autoconf。另外，安装iftop还需要安装libpcap和libcurses。在Xen Server上安装所需的依赖包:1yum  --enablerepo=base install flex byacc libpcap ncurses ncurses-devel libpcap-devel安装iftop：1wget ftp://fr2.rpmfind.net/linux/dag/redhat/el5/en/i386/dag/RPMS/iftop-0.17-1.el5.rf.i386.rpm2rpm -ivh iftop-0.17-1.el5.rf.i386.rpm运行iftop：直接运行iftop即可附件：《iftop的详细参数及说明》《如何给Xen server安装GCC》
