RHCA CL220 The KVM deployment of the real-combat series (i) cloudforms

1. Overview

Red Hat has launched a hybrid cloud cloudforms solution, Redhat's mission is to achieve a centralized management platform through Cloudforms's ability to manage all infrastructure facilities such as Rhev,vmware and the Cloud (AWS and OpenStack). Cloudforms by engine engines, Vmdb virtual database and so on, which engine as the core function of cloudforms, responsible for the daily management of Cloudforms.

CloudForms engine, abbreviated as CFME, is a well-established virtual machine that can be deployed quickly to CloudForms environments by deploying the virtual machine. Because it is a virtual machine, depending on the environment, can be deployed on the non-virtualized platform, and based on the virtual platform is not available, from the virtual machine, such as VMware Platform, Rhev platform, OpenStack platform. This article takes the deployment of KVM as an example to describe the deployment of cloudforms Egine.

2. Deploy cloudforms via KVM

1. Create and modify configuration files for a virtual machine

[Email protected]_10_16_2_9 ~]# cp/etc/libvirt/qemu/centos-5.9.xml/etc/libvirt/qemu/cfme.xml

Modify the following content:

A, name <name>cfme</name>

B, UUID <uuid>ba845a90-8670-4b89-9451-3a111372950c</uuid> generate a new number via Uuidgen

C, Memory <memory unit= ' KiB ' >4194304</memory>

D, CPU <vcpu placement= ' static ' >4</vcpu>

E, boot sequence <boot dev= ' HD '/>

F, Disk File

<disk type= ' file '  device= ' disk ' >                                                       #磁盘类型为file     <driver name= ' qemu '  type= ' qcow2 '  cache= ' None '/>                                 # Drive type and format     <source file= '/var/lib/libvirt/images/cfme.qcow2 '/>                               #磁盘文件路径, extracting from Cloudforms for     <target  dev= ' Vda '  bus= ' virtio'/>                                                  #磁盘名字和总线类型为virtio      <address type= ' PCI '  domain= ' 0x0000 '  bus= ' 0x00 '  slot= ' 0x04 '  function= ' 0x0 '/ >    @@@ Note that to remove @@@, the bus address will conflict </disk><disk type= ' file '  device= ' disk ' >    <driver name= ' qemu '  type= ' qcow2 '  cache= ' None '/>     <source file= '/var/lib/libvirt/images/cfme_vdb.qcow2 '/>     # The disk is located on the path, subsequent creation     <target dev= ' VDB '  bus= ' virtio '/>                               #磁盘为vdb </disk> 

G, network card

<interface type= ' network ' > <mac address= ' 52:54:00:00:00:0c '/> #mac地址 <source network= ' Br-eth0 ' /> #桥接网卡, @@ Note @@@ Here is the OvS Bridge, if the KVM Bridge, please modify the br0 <virtualport type= ' Openvswitch ' ></virtualport>    ; #由于使用openvswitch网桥, need to add, br0 do not <model type= ' Virtio '/></interface>

H, VNC

<graphics type= ' vnc ' port= '-1 ' autoport= ' yes ' listen= ' 0.0.0.0 ' > #用于VNC连接 to prevent no graphical interface <listen type= ' address ' address= ' 0.0.0.0 '/></graphics>

After the

has been modified, the contents of the virtual machine's configuration file are as follows:

2. Get the cloudforms virtual machine

In order to make it easy for everyone to use, I have placed the connection path in the network disk: Network address: Http://pan.baidu.com/s/1hrrmtec

3. Unzip the CFME virtual machine
