Rocky9.2安装KVM

一级目录

查看CPU是否支持虚拟化

cat/proc/cpuinfo|egrep'vmx|svm'

查看是否加载KVM

lsmod|grep kvm

若没有加载KVM，则加载模块

modprobe-a kvm modprobe-a kvm_intel

关闭Selinux

vim/etc/selinux/config----------------------------------------SELINUX=disabled----------------------------------------

setenforce 0

更新源以及安装epel源

dnf update && dnf install epel-release

安装KVM和管理工具

dnf install qemu-kvm virt-manager libvirt virt-install virt-viewer virt-top bridge-utils bridge-utils virt-top libguestfs-tools-y

启动libvirtd守护进程

systemctlstartlibvirtd && systemctl enable libvirtd && systemctl status libvirtd

配置KVM的网段，本案例采用NAT模式

virsh net-edit default

修改自定义的IP网段以及掩码和网关

<network> <name>default</name> <uuid>804211be-e428-4e2b-84a3-5c41909891c5</uuid> <forward mode='nat'/> <bridge name='virbr0'stp='on'delay='0'/> <mac address='52:54:00:29:8e:44'/> <ip address='192.168.123.254'netmask='255.255.255.0'> <dhcp> <rangestart='192.168.123.1'end='192.168.123.200'/> </dhcp> </ip> </network>

从指定xml配置文件定义一个网络或者基于指定xml来修改现有网络

virsh net-define/etc/libvirt/qemu/networks/default.xml virsh net-startdefault

重启libvirtd守护进程

systemctl restart libvirtd && systemctl status libvirtd
