2020.05.6 – Install CentOS 8 Server on VMware ESXi

This page inspire me: https://linuxhint.com/install_centos8_vmware_esxi_server/

Note: This version is without GUI. If needed chose Server with GUI.

The inspiration is very good. I have some differences and I will put here.


  • Install into MacBook Pro > VMware Fusion > VMware ESXi
  • Click ESXi web client > Datastore browser > Create directory with name CentOS
  • Different Hard Disk and Network Adapter
  • Host Name: CentOS
  • Tipe and Data: for Romania
  • Username: silvia and mine password
  • Include also Root password

All other are exactly as in the helping blog.

2020.05.2 – Connecting EVE Lab to a physical device

Some help ideas are in EVE professional Cookbook.

A virtual lab that include CentOS is configured in EVE-PRO. The EVE-PRO is configure in VMWare Fusion. VMware Fusion is in MacBook PRO. The idea is to connect virtual CentOS to internet.

Open VMware Fusion > Click on EVE-PRO virtual machine > Click on Settings…

Create, or select if already created, 3 Network Adapter:

  • Network Adapter > Connect to vSphere network
  • Network Adapter 2 > Connect to vSphere network
  • Network Adapter 3 > Connect to vSphere network

Into EVE-PRO lab create a new Network type Cloud1 and connect to CentOS. Do not forget to configure the correct IP in CentOS. Details of how I done it are here: 2020.04.30 – CentOS installation into EVE-NG.

The Internet is working now

I am happy!!!

2020.04.30 – CentOS installation into EVE-NG

All used information to install I found here:

Using things:

  • EVE-PRO meaning with license
  • CentOS CentOS-8.1.1911-x86_64-dvd1.iso

Step 1. Download CentOS – donloaded from Download CentOS version Linux DVD ISO

See 2. Go into EVE-PRO and move into qemu directory

root@eve-ng:~# cd /opt/unetlab/addons/qemu

Step 3. Create a new directory and move inside it

root@eve-ng:/opt/unetlab/addons/qemu# mkdir linux-centeros-8
root@eve-ng:/opt/unetlab/addons/qemu# cd linux-centeros-8

Step 4. Upload CentOS-8.1.1911-x86_64-dvd1.iso in EVE-PRO using FilaFilla application

root@eve-ng:/opt/unetlab/addons/qemu/linux-centeros-8# ls

Step 6. Create qcow2 file

root@eve-ng:/opt/unetlab/addons/qemu/linux-centeros-8# /opt/qemu/bin/qemu-img create -f qcow2 hda.qcow2 40G
Formatting 'hda.qcow2', fmt=qcow2 size=42949672960 encryption=off cluster_size=65536 lazy_refcounts=off refcount_bits=16

root@eve-ng:/opt/unetlab/addons/qemu/linux-centeros-8# ls
CentOS-8.1.1911-x86_64-dvd1.iso  hda.qcow2

Step 6. Rename CentOS-8.1.1911-x86_64-dvd1.iso file

oot@eve-ng:/opt/unetlab/addons/qemu/linux-centeros-8# mv CentOS-8.1.1911-x86_64-dvd1.iso cdrom.iso

root@eve-ng:/opt/unetlab/addons/qemu/linux-centeros-8# ls
cdrom.iso  hda.qcow2

Step 7. Login to EVE-PRO then Add new lab end add CentOS node

CentOS need to have

  • Name: CentOS
  • CPU: 2
  • RAM (MB): 4096
  • Ethernets: 2
  • QEMU Version : 2.4
  • QEMU arch: tpl (x86_64)
  • QEMU Nic: e1000-

Click SAVE

Add a switch and configure it as Type: Management (Cloud0) and click Save


Step 8. Now ready to start CentOS

Do not click anything, just wait …

Step 9. Go throw installation process

English and Continue

Verify and configure different things…

Keuboard: English

Software: Server with GUI

Installation Destination: ATA QENU HARDDISK

After finishing click Begin Installation

During installation you need to insert toot password and user name and password

Root Pasword

User Name and Password. Also select Make this user admin

Wait to finish installation

Step 10. Restating CentOS

Before restarting CentOS you need to modify the name if application needed to install

root@eve-ng:/opt/unetlab/addons/qemu/linux-centeros-8# mv cdrom.iso centos-install.iso

I do not like restart. I click restart, then power-off and them power-on or Start

Step 11. Go throw internal installation process.

Click License Information

I accept the license agreement.

Click Finish configuration

English and Next

English (US) and Next

Privacy OFF and Next

Connect Your Online: Skip

Finish to install internal

Step 12. Networks

Select Wired Settings

I don’t have Automatic Ethernet on these network, si I have to configure it manually

Open Terminal

Use ifconfig command

I will do not this now ….

Step 13. Save the configured CentOS for all new EVE-PRO lab

Into EVE-PRO open Lab Details


root@eve-ng:/opt/unetlab/tmp/0/085884f1-7807-492d-814f-7b588fd1892c/1# ls
cdrom.iso  hda.qcow2  l1down_1  l1up_0  mon-sock  mon2-sock  qmp-sock  wrapper.txt

root@eve-ng:/opt/unetlab/tmp/0/085884f1-7807-492d-814f-7b588fd1892c/1# /opt/qemu/bin/qemu-img commit hda.qcow2

Image committed.

Here is tha same

root@eve-ng:/opt/unetlab/tmp/0/085884f1-7807-492d-814f-7b588fd1892c/1# ls
cdrom.iso  hda.qcow2  l1down_1  l1up_0  mon-sock  mon2-sock  qmp-sock  wrapper.txt

A needed command to make it work as configured

root@eve-ng:/opt/unetlab/addons/qemu/linux-centeros-8# /opt/unetlab/wrappers/unl_wrapper -a fixpermissions

May 01 07:09:28 May 01 07:09:28 Online Check state: Valid

All done. CentOS is ready to go. We will now add a couple of nodes to confirm that CentOS is working.

Step 14. Verify that CentOS is working

Add a total of three CentOS

Power-on all

All 3 can power-on …

Step 14. Configure and Mange Network Connection using nmcli

The needed information I find here: How to configure and Manage Network Connections using nmcli. I use The nmcli connection sub-command chapter.

  • View connection profiles
# nmcli connection show 
virbr0 bbe539aa-7042-4d28-a0e6-2a4d4f5dd744 802-3-ethernet virbr0

$ nmcli connection add con-name new-ens4 ifname ens4 type ethernet ip4 gw4

/etc/sysconfig/network-scripts/ifcfg-ens4 /etc/sysconfig/network-scripts/ifcfg-new-ens4

I can see this but I modify using nmcli command

I hope all detail help me and you in future use.
