How to changing XenServer Management IP Address 修改XenServer管理IPToday i am in customer who want to test our XenServer, but they give me a used IP Address, so we must change the XS IP Address. Catuion we can not use the Linux command line to change it, if u use Linux command line i think that is not a good idea,your XS will be crush, so the right way is use XenServer Command line.1. Login to the XS console as root2. Use the “xe pif-list” command to list the physical interfaces to findthe management interface and it...
rhel6/RHEL7 yum 源配置 RHEL6.2配置本地yum源和第三方源 yum可以自动解决软件包的依赖问题,简化软件安装,但RHEL的yum源是收费的,无法使用,要方便的使用yun,就必须为其添加免费的yum源。免费yum源一般有两种:本地yum源和第三方yum源。下面本文将简明的介绍两种yum源的安装配置过程。一、RHEL6.2配置本地yum源 本地yum源是将RHEL6.2安装光盘里的软件包作为本地源,因为安装光盘里的软件包已经十分全面,一般无需额外的软件包即可满足日常需求。相对与网络上的yum源,本地源速度很快,来自官方支持,十分稳定,是很不错的选择。 配置本地yum源步骤如下: (1)将rhel6.2安装光盘镜像(名为rhel.iso)拷到硬盘备用,此例位置为/home/lee/documents/Softwares/OsImages/rhel.iso (2)创建iso镜像挂载目录#mkdir /localiso (3)修改/etc/fstab文件挂载镜像(也可将iso内容拷贝到 /localiso目录下) #vi /etc/fstab 在最后一行加入如下信息: &n...
centos6 安装wmwaretools找不到kernel headerfyi:http://blog.secaserver.com/2011/09/linux-vmware-tools-installation-error/ Linux: VMware Tools Installation Error BySecaGuyOn30 September 2011 · Leave a Comment Yesterday, I was installing a new CentOS 6 server within VMWare Workstation 7 to be a file server for internal usage. As usual, it is highly recommended to install VMWare Tools to every guest operating system we installed to make sure the hardware integration will be smooth and avoid degraded performance on the virtual server. During the installation process, I found following error: Searching for a valid kernel header path...
The path "" is not valid.
Would you like to change it? [yes]
What is the location of the directory of C header files that match your running kernel?What VMWare needs is the kernel-header and kernel-devel package from the same version with your current loaded kernel. You can check your loaded kernel by using following command:$uname -r

Hyper-V虚拟机,支持Aero和高清播放前几天简单测试了2008R2的Hyper-V动态内存扩展今天无聊测试了一下远程桌面连接Hyper-V的3D功能,的确很强大!2008 R2 SP1 下载地址:http://download.microsoft.com/download/0/A/F/0AFB5316-3062-494A-AB78-7FB0D4461357/windows6.1-KB976932-X64.exe1.Hyper-V可以在虚拟机中直接添加RemoteFX显卡,添加之後只能用MSTSC管理虛擬豬。2.Hyper-V虚拟的windonws7系统,可以在2008R2实体机中通过远程桌面连接到虚拟机里的系统,此时可以在虚拟桌面里实现Aero效果和其它3D应用。尝试了一下在远程桌面里播放高清电影,大出意外,竟然支持硬件解压高清电影视频,并且图像清晰,声音流畅,与实体机里播放高清的效果相当。并且比安装了Hyper-V的实体机播放高清还要更加流畅一些。相信微软的RemoteFX技术在填补了远程3D应用的空白后,有着很好的应用前景。远程桌面连接上Hyper-V里的虚拟机后,此连接里直接调用实体机的3D功能和声频功能,实现的3D效果还算可以,当然需要改进,还不是很流畅。声音效果还比较好。播放高清AV不帶卡2.jpg4.jpg
Xenserver中将一台Server加入到Pool的条件 1.基本环境a)与master Server的CPUs一定要相同(厂商\型号\功能);b)相同的XS安装光盘和相同的Patch以及软件;2.本身a)时间一定要相同(建议使用NTP)b)没有创建任何shared storage,VMs3.同一个Pool最多支持16台Server4.强制将Server加入到Pool中Resouce pool configuration-->Join resource pool (forced)

Fedora17上安装oVirt Engine 3.1 ovirt engine 3.1已经release了,尝试在F17上安装了一下,也不那么顺利,主要是因为对jboss不熟悉。几天下来,终于搞定了,把大概的步骤记录下:1. 配置ovirt engine的repo# cd /etc/yum.repos.d/# wget http://www.ovirt.org/releases/3.1/rpm/Fedora/17/ovirt-engine.repo2. 安装ovirt engine# yum install ovirt-engine-3.13. 设置ovirt, 这一步必须保证selinux是enforcing的。# engine-setup4. 最后的workaround, 非常重要,要不然ovirt engine起不来。# ln -s /usr/share/java/jboss-jaxr-1.0-api.jar /usr/share/jboss-as/modules/javax/xml/registry/api/main/jboss-jaxr-1.0-api.jar# ln -s /usr/share/java/xmlsec.jar /usr/share/jboss-as/modules/org/apache/santuario/xmlsec/main/xmlsec.jar# systemctl restart ovirt-engine.service
