Ironic , Openstack Baremetal Hypervisor,首发于UnitedStack Inc.. 转自: http://ju.outofmemory.cn/entry/48769 如今Openstack在虚拟化管理部分已经很成熟了, 通过nova我们可以创建虚拟机, 虚拟磁盘, 管理电源状态,快速通过镜像启动虚拟机.但是在物理机管理上一直没有成熟的解决方案. 在这样的背景下Ironic诞生了,它可以解决物理机的添加,删除,电源管理和安装部署.Ironic最大的好处是提供了…

安装及配置 由于Ironic的配置很长,下面我们简短的说一下安装和配置过程,具体的安装配置教程参考官方手动配置教程或者使用devstack安装. Ironic需要与Nova.Neutron.Glance.Keystone等进行交互,于是先要对这些进行配置. 1.配置KeyStone 首先我们需要在keystone中创建ironic用户.服务.endpoint信息. keystone user-create keystone user-add-role keystone servcie-creat…

介绍 ironic-inspector是一个用于硬件自检的辅助型服务,它可以对被ironic组件管理的裸金属节点进行硬件自检,通过在裸金属节点上运行内存系统,发现裸金属节点的硬件信息,例如CPU数量和型号.内存容量.磁盘数量和型号.各种PCI设备等等,最终将这些信息记录于ironic组件的数据库中. ironic-inspector的存在拓宽了ironic组件发现裸金属节点硬件信息的能力.在没有ironic-inspector之前,ironic所获取的裸金属节点信息来源于用户的手动输入,这不但效…
