4 provisioning virtual machines
第4章主要是講如何在CFME創建虛擬機，主要有3種方式：native clone/iso/pxe。
主要是2個web界面的內容：
infractructure>virtual machine/PXE創建虛擬機操作界面。
service>request創建虛擬機進度等信息。
Provisioning via Native Clone
理論
1. 概述
基礎設施可以發佈資源和管理它們的生命週期。
資源包含：虛擬機/存儲空間/或者其它基礎設施可管理的資源。
通過CFME配置虛擬機有三種方式：template(native clone)/ISO/PXE
2. 如何配置虛擬機？
配置虛擬機有8大選項
request:指虛擬機的管理員信息，例如郵箱，姓名等。
purpose:虛擬機屬於哪個tag，例如一個catelogies可能是一個項目，然後tag是這個項目的標記，指虛擬機屬於哪個項目。
catelog：虛擬機的基本信息，例如多少臺虛擬機，虛擬機是通過哪種方式創建的(模板/ISO/PXE)，虛擬機的名字等。
environment:指虛擬機創建在哪，例如哪個集羣，運行在哪臺主機，存放在哪個存儲域上等。
hareware:指虛擬機的硬件信息，例如CPU個數，內存多大等。
network:虛擬機所在的網絡。
customize:指定製虛擬機的密碼，IP，DNS等。
schedule:指虛擬機在什麼時候創建，什麼時候開機等。

實驗
1. 下載rhel的ova模板
2. 將rhel的ova導入到rhevm
3. 在RHEV平臺創建rhev模板
4. 在CFME通過模板配置VM
5. 監控配置信息，配置進度等
6. 檢驗VM是否配置成功
Defining ISO Image Type
理論
1. 概述
另一種配置虛擬機的方式是ISO。
但通過官方的ISO需要手動安裝，無法自動安裝，這裏您需要自定義isolinux中的ks文件，然後生成一個自定義的ISO，使其可以自動安裝。
自定義ISO:
https://jingyan.baidu.com/article/c1a3101eef3ee6de656debb8.html
2. CFME如何配置ISO
首先需要配置ISO datastore。
導航：infrastructure>PXE>ISO datastore添加一個現有的provider(例如RHEV)中的iso。
添加完後需要點刷新”relationship”，纔會出現RHEV平臺中的ISO。
接着需要edit它的iso type，這裏我選的rhel6。
iso type可以通過左邊導航的上級選項”system image type”來添加。
3. 通過自定義ISO配置虛擬機
紅帽給的自定義ISO有問題：卡在這裏了
這個自定義ISO會自己創建一個3G的磁盤(和上面的template一樣)。
這裏使用的ISO是rhel-server-6.5-x86_64-custom.iso，其實這隻一個引導盤，裏面的KS文件沒啥用。本單元主要是爲下個單元做準備。
如果您需要通過自定義ISO配置虛擬機，也可以自己創建自定義的ISO與KS文件。
實驗
1. 下載自定義的ISO
2. 上傳ISO到RHEV平臺
3. 在CFME創建ISO datastore
4. 創建system image type
5. 將剛剛創建的system image type和ISO datastore中的ISO關聯
Provisioning via Customization Templates
理論
1. 概述
在一些企業可能需要一個定製化的虛擬機。
這時您可以通過”自定義模板”來配置虛擬機:
windows:syspre file
linux: ks file
2. 製作自定義光盤
如何做一個定製化的iso，使系統自動根據我們預定義好的參數來安裝系統呢？
這裏需要用到ks文件，並在引導光盤時自動加載ks文件的效果。通過光盤引導系統時會加載光盤中isolinux中的isolinux.cfg，從而得到引導列表，那麼可以在讀取某個引導列表中的選項時自動讀取ks文件，這裏只需將ks文件的路徑加到引導項中就可以實現自動安裝。
下面在F0安裝kickstart工具，然後製作一個最小化安裝的自定義centos7光盤，達到不用人爲選擇安裝項，自動安裝定製化系統的效果。
官方centos小最化的鏡像：CentOS-7-x86_64-Minimal-1611.iso
步驟：
yum install -y system-config-kickstart #安裝ks文件製作工具
system-config-kickstart #打開圖形化的ks文件製作工具，製作好後將ks另存爲ks.cfg
mkdir /mnt/iso #光盤的掛載目錄
mount /dev/sr0 /mnt/iso/ #將光盤掛載
mkdir hrr #新建一個目錄，用於放從光盤拷貝過來的文件
cp -arp /mnt/iso/* hrr/ #將光盤的文件全部拷貝到新目錄中
vim isolinux.cfg #在isolinux.cfg中定義ks文件路徑，這裏ks.cfg放在hrr目錄中
cat isolinux.cfg #以下是isolinux.cfg的內容

通過vmware測試：這裏密碼是1
default more是第一個
CFME安裝：只選ISO方式，不選自定義的template否則虛擬機加載不到光盤。
按ALT+TAB可以切換不同的界面，第一個是安裝，第二是命令行，第三是日誌，第四是日誌，第五是日誌，第六又開始從第一循環。
3. 設置自定義模板
導航：infrastructure>PXE>customization template
4. 通過自定義模板與ISO配置虛擬機
這裏在創建虛擬機時，有把ISO選上的，但它沒有加載到，需要人工來設置。
先在CFME暫停虛擬機,然後到RHEV平臺把虛擬機關機並把光盤掛載上並run once.
光盤中的isolinux.cfg的內容：
光盤中的ks文件的內容：
從這裏得出：
L紅帽給的自定義光盤中的isolinux有寫:ks文件在floppy中，但系統沒找到ks文件。
L然後在CFME定義的KS文件並沒有生效，現在需要自己寫cla***oom上的ks文件地址，但這又有問題來了，cla***oom中的ks文件中的passworld等是引用CFME的customize定義的變量，這裏只是引用cla***oom的KS，於是這個KS文件需要自己修改密碼，否則不知道root密碼。
解決方法：
將其他地址的ks文件中的root加密代碼複製到，我們需要引用的ks文件的root密碼上，這樣就知道root密碼是啥了。(我這裏複製的是rhevm中的.cfg文件，root密碼是redhat)
實驗
1. 創建自定義模板
2. 通過ISO配置VM(customize那選custom template)
3. 監控配置VM信息/進度
4. 當cfme的監控進度爲waiting時將vm暫停，到RHEV平臺將VM關機，掛光盤給vm並設置爲run once
5. 檢驗VM是否配置成功
Provisioning via PXE
理論
1. 概述
另一種配置虛擬機的方式是PXE，引導是通過網絡來啓動的，也就是引導盤不在RHEV平臺，而是在一臺遠端PXE服務器上。
2. 什麼是pex
PXE(preboot execute environment，預啓動執行環境)是由Intel公司開發的最新技術，工作於Client/Server的網絡模式，支持工作站通過網絡從遠端服務器下載映像，並由此支持通過網絡啓動操作系統，在啓動過程中，終端要求服務器分配IP地址，再用TFTP（trivial file transfer protocol）或MTFTP(multicast trivial file transfer protocol)協議下載一個啓動軟件包到本機內存中執行，由這個啓動軟件包完成終端（客戶端）基本軟件設置，從而引導預先安裝在服務器中的終端操作系統。PXE可以引導多種操作系統，如：Windows95/98/2000/windows2003/windows2008/winXP/win7/win8,linux系列系統等。
3. 在cfme配置PXE
導航：infrastructure>PXE>PXE server
CFME3.1 depot倉庫支持的文件系統是samba/nfs
實驗
