在研究桌面云的過程中，發(fā)現(xiàn)對于真正落地來說，服務(wù)端（私有云或者虛擬化）沒有太多的區(qū)別，更多的是瘦客戶端的使用和對桌面的管理方面有諸多需要考慮的地方，最終落地可能都是需要定制化開發(fā)才能很好的滿足需求。

成都創(chuàng)新互聯(lián)公司是一家集網(wǎng)站建設(shè),城區(qū)企業(yè)網(wǎng)站建設(shè),城區(qū)品牌網(wǎng)站建設(shè),網(wǎng)站定制,城區(qū)網(wǎng)站建設(shè)報價,網(wǎng)絡(luò)營銷,網(wǎng)絡(luò)優(yōu)化,城區(qū)網(wǎng)站推廣為一體的創(chuàng)新建站企業(yè)，幫助傳統(tǒng)企業(yè)提升企業(yè)形象加強(qiáng)企業(yè)競爭力?？沙浞譂M足這一群體相比中小企業(yè)更為豐富、高端、多元的互聯(lián)網(wǎng)需求。同時我們時刻保持專業(yè)、時尚、前沿，時刻以成就客戶成長自我，堅持不斷學(xué)習(xí)、思考、沉淀、凈化自己，讓我們?yōu)楦嗟钠髽I(yè)打造出實用型網(wǎng)站。

在開源虛擬化產(chǎn)品中，限于自己的經(jīng)驗和眼界，Ovirt原來一直沒有接觸，在和朋友的溝通過程中，發(fā)現(xiàn)Ovirt對于桌面云解決方案更接地氣，更具有項目落地的優(yōu)勢。

這里記錄一下第一次安裝oVirt測試環(huán)境熟悉過程。

Ovirt官網(wǎng)安裝參考：

https://ovirt.org/documentation/install-guide/Installation_Guide.html

安裝前準(zhǔn)備：

下載CentOs7.8和Ovirt-node 安裝鏡像：

CentOS-7-x86_64-DVD-1908

oVirt-engine官網(wǎng)安裝文檔：

https://ovirt.org/documentation/install-guide/chap-Installing_oVirt.html

在自己的PVE測試環(huán)境中創(chuàng)建1個虛擬機(jī)安裝centos7.8 安裝ovirt引擎 。

編輯 /etc/hosts文件：

192.168.170.110 ovirt-manager.yuweibing.com ovirt-engine

配置IP地址（略）

修改主機(jī)名（略）

根據(jù)上面oVirt-engine官網(wǎng)安裝文檔逐步進(jìn)行安裝，其中，執(zhí)行下面命令：

?#?yum?install?ovirt-engine

的時候花了很長時間，主要是下載包的時間花了較多的時間，網(wǎng)絡(luò)速度很慢，大概10k-20k左右甚至更低，400M的包花了幾個小時下載完。

之后，需要配置ovirt-engine

對postgresql數(shù)據(jù)庫不熟悉，隨便參考網(wǎng)上新手教程：

http://www.ruanyifeng.com/blog/2013/12/getting_started_with_postgresql.html

更詳盡的教程：

進(jìn)行配置初始化：

安裝成功。需要使用域名訪問web管理網(wǎng)頁：

編輯本機(jī)的 c:\windows\system32\drivers\etc\hosts文件，增加：

192.168.170.114 ovirt-host1.yuweibing.com ovirt-host1

然后訪問網(wǎng)址：
