1 You need to understand

• Appointment ： We call it running on VMware Workstation The virtual machine inside is Client virtual machines （ hereinafter referred to as The virtual machine , use CentOS 7.8 Graphical ）; We call it in The virtual machine It's based on KVM The running virtual machine is KVM virtual machine （ hereinafter referred to as KVM The virtual machine , use CentOS 7.4）, Yes , Two layer dolls
• The virtual machine Before starting , Must be in VMware Workstation Start the virtualization engine on virtualization Intel VT-x/EPT or AMD-V
• Suggest The virtual machine The network configuration is NAT or The bridge , Because the future KVM The virtual machine Need help The virtual machine Internet capability to install software packages
• You can refer to the following related articles G016 complete CentOS Installation and G019 and G020 complete RedHat OpenStack Environment construction and basic operation

2.3 install KVM The virtual machine

2.3.1 Language choice

2.3.2 Automatic partition

2.3.3 Network and host name

Be careful ： When the network is turned on , Must be able to pass DHCP Automatically get IP Address , Here's the picture

2.3.4 To configure ROOT password

Minimize by default minimal install

2.3.5 Restart and test the network

restart kvm The virtual machine , And root Identity login , test kvm The virtual machine Can you connect to the external network

3 To configure KVM virtual machine

3.1 modify KVM Virtual machine network configuration file

Be careful ： The change is kvm The virtual machine , No The virtual machine , Unclear concept ？ Refer to part I Appointment

Log in and copy

#  modify  kvm  Virtual machine network card configuration file , Make it include only the following  4  Row content 
[[email protected] ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0 
[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
