oVirt Overview

Physical architecture

oVirt consists of the following bits:

1. A stripped-down Fedora build that installs and runs off a CD, a usb key, or a ramdisk (over PXE) on a physical host. The build contains all the necessary pieces to support hosting and managing virtual machines on the host.
2. A web-based management UI application for oVirt hosts, users, and vms.
3. The FreeIPA ldap/kerberos identity, policy, and audit application.

Logical architecture

The bits above connect in the following ways:

• The FreeIPA application handles kerberos administration, authentication, and authorization for the entire app.
• An oVirt host image is provided with the application. On boot (via cdrom, flash drive, or PXE), the host image loads its keytab and kerberos configuration from the oVirt management application and announces itself.
• The oVirt management application authenticates with FreeIPA and can then communicate with the libvirtd running on each oVirt host via an encrypted SASL connection using the libvirt SASL infrastructure.
• An iSCSI target, running on any machine reachable from the oVirt host, provides disk storage for oVirt guests. The oVirt host will automatically make the storage targets on the iSCSI server it is configured for available for oVirt guest installs.

采用libvirt进行管理，带iscsi存储，web ui 和 ldap等，不知道性能怎样，研究好libvirt后研究一下这个。

Red Hat 在本周宣布了一个新的虚拟化平台管理软件──。oVirt 是基于 项目的开源软件，该虚拟机软件支持主流的 x86 硬件，并允许用户在其上运行 Linux 及 M$ Windows 操作系统。

oVirt 提供基于 Web 的虚拟机管理控制平台，无论是一台主机上的几个虚拟机，还是管理数百台主机上的成千个虚拟机，它皆能胜任。

目前，oVirt 所发布的最新版本为 0.91-1 beta，可从这里到适用于 i386 和 x86_64 架构的安装文件。值得注意的是，运行 oVirt 除了要求硬件具有虚拟化支持外，还应事先安装好 kvm、libvirt、virt-manager、virt-viewer 等软件。
