【centos8】用kvm安裝虛擬機

一  環境準備 

 pc機 1T硬盤 16G內存  

vmware workstation 15  

最小安裝 centos8 操作系統；配置支持虛擬化

配置源 

系統自帶的源能用；最好是配成國內的阿里源

二 安裝 軟件

yum groupinstall  "Virtualization Host"  

查看安裝完後

[root@localhost ~]# virsh version
Compiled against library: libvirt 4.5.0
Using library: libvirt 4.5.0
Using API: QEMU 4.5.0
Running hypervisor: QEMU 2.12.0

[root@localhost ~]# 

 

三 創建虛擬機

 

1  下載系統鏡像到 /root/images 路徑

2  創建虛擬機磁盤 

    qemu-img create -f  qcow2   /root/images/disk.qcow2   50G

3 創建虛擬機

[root@localhost images]# virt-install --name vm01 --ram 2048 --vcpu=2 --disk path=/root/images/disk2.qcow2 --vnc --vncport=5910 --vnclisten=0.0.0.0  --arch=x86_64 --bridge=virbr0 --cdrom /root/images/CentOS-7-x86_64-DVD-1908.iso
WARNING  Graphics requested but DISPLAY is not set. Not running virt-viewer.
WARNING  No console to launch for the guest, defaulting to --wait -1
