备份和还原 vCenter Server Appliance vPostgres 数据库 (2096200) Purpose 免责声明：本文为 Backing up and restoring the vCenter Server Appliance vPostgres database (2034505) 的翻译版本。尽管我们会不断努力为本文提供最佳翻译版本，但本地化的内容可能会过时。有关最新内容，请参见英文版本。 本文提供了备份和还原 vCenter Server Appliance (VCSA) vPostgres 数据库的步骤。注意：本文仅支持将 vPostgres 数据库备份和还原到同一 vCenter Server Appliance。使用基于映像的备份和还原是执行完整的辅助设备还原所支持的唯一解决方案。 Resolution 在开始之前，请确保已安装：用于连接到 vCenter Server Appliance 的 SSH 客户端。 用于检索和替换 vPostgres 数据库恢复文件的 WinSCP（或任何 SCP 客户端）。 备份嵌入式 vPostgres 数据库 要备份嵌入式 vPostgres 数据库，请执行以下操作：通过 SSH 连接到 vCenter Server Appliance。有关详细信息，请参见 vCenter Server 5.5 and Host Management Guide 中的在 VMware vCenter Server Appliance 上启用或禁用 SSH 管理员登录部分。 出现提示时，以 root 用户身份登录。默认密码为 vmware。 使用以下命令停止 v...

如何备份和恢复VCSA 5.5自带的vPostgres数据库   大家都知道VCSA内置的数据库从5.1开始已经换成了vPostgres这个VMware基于开源数据库PostgresQL开发的vFabric系列产品了，那么，如何对它执行备份，以确保对于VCSA的用户体验能够和MS或Oracle数据库一样都能够起到安全增强呢？ 首先，数据库的安全就会涉及到备份了，而我们在VAMI UI上面是没有找到如何备份这个VCSA的数据库的，更不用说恢复了，因此，本文就着眼于如何备份和恢复它了； 1、利用SSH或者直接登录到VCSA 5.5的CLI界面，缺省用户名为root，缺省密码为vmware； 2、然后执行如下命令，将路径切换到vpostgres程序所在目录：      #cd /opt/vmware/vpostgres/1.0/bin3、执行如下命令备份VCSA 5.5的vpostgres数据库：      #./pg_dump EMB_DB_INSTANCE -U EMB_DB_USER -Fp -c > VCDB_Backup  说明：VCDB_Backup这个名字可以自由定义，它就是备份出来的文件名； 4、注意，需要EMB_DB_USER的密码，可以在如下路径的文件中找到：      /etc/vmware-vpx/embedded_db.cfg 利用vi编辑器或...

Installing VMware vGPU on vSphere 6.0Install & ConfigurationPublished 7 March 2015 at 11:51Comments Off on Installing VMware vGPU on vSphere 6.0 Share this post:on Facebookon Google+on TwittervGPU is a concept where an user of a virtual desktop can utilise the power of a GPU for running rich 3D applications, such as AutoCAD or other drawing applications, rendering or just watching full HD youtube. In this concept, the virtual desktop gets a direct or shared line to the GPU for 3D processing on any device.NVIDIA is the catalyst behind this technology and the hypervisor layer has to support this for you to be able to take advantage of this powerful tech. Citrix has been supporting this for a while, Microsoft has RemoteFX, but VMware has not joined this club until very recently with vSphere 6.0.vGPU is supported on the NVIDIA GRID K1 and K2 cards, with four vGPU profiles each. These vGPU profiles are resource profiles which you can assign to virtual desktops. Below is an overvie...

MultiOS Gaming, Media, and OpenCL Using XenGT Virtual Machines On Shared Intel GPUs December 1, 2014 by Rob Farber 2 Comments At last, a full (opensource!) GPU virtualization solution that allows virtualized guest operating systems to “own” a shared Intel GPU yet allows applications to run with near-native performance! This means games, both DRM and free media, plus OpenCL applications can  run in separate guest operating systems on a single Intel GPU system (convenient for users) or in a shared cloud environment (a nice feature that can be offered by cloud providers). This is an Intel-only GPU solution. For more about other – non-Intel – GPU virtualization solutions, see our popular TechEnablement article, “MultiOS Gaming CUDA & OpenCL Via a Virtual Machine“.Full GPU Virtualization on Intel GPUs (image courtesy the Linux foundation)Performance is reported to be within 95% of utilizing the native GPU in a non-virtualized environment:XenGT provides ne...
