In the process of studying the desktop cloud, it is found that there is not much difference between the server (private cloud or virtualization) and the application of thin client and the management of the desktop. The final landing may require customized development to meet the needs.
In the open source virtualization products, limited to their own experience and vision, Ovirt has never been contacted before. In the process of communication with friends, it is found that Ovirt is more grounded for desktop cloud solutions and has the advantage of project implementation.
Here's a record of the familiarization process of installing oVirt test environment for the first time.
Ovirt official website installation reference:
https://ovirt.org/documentation/install-guide/Installation_Guide.html
Preparation before installation:
Download CentOS 7.8 and ovirt node installation images:
CentOS-7-x86_64-DVD-1908
ovirt-node-ng-installer-4.3.6-2019092614.el7
Ovirt engine official website installation document:
https://ovirt.org/documentation/install-guide/chap-Installing_oVirt.html
Create two virtual machines to install CentOS 7.8, one to install the ovirt engine, and one to install the host in your own PVE test environment.
Edit the / etc/hosts file:
192.168.170.110 ovirt-manager.yuweibing.com ovirt-engine
192.168.170.114 ovirt-host1.yuweibing.com ovirt-host1
Configure IP address (omitted)
Modify host name (omitted)
Install step by step according to the above ovirt engine official website installation document, where, execute the following command:
# yum install ovirt-engine
It took a long time to download the package. The network speed was very slow, about 10k-20k or even lower. The 400M package took several hours to download.
After that, you need to configure ovirt engine
Not familiar with postgresql database, please refer to the online novice tutorial:

Installation succeeded. You need to use the domain name to access the web management page:
Edit the c:\windows\system32\drivers\etc\hosts file of this computer, and add:
