云计算基础-在宿主机上安装QEMU-KVM软件

1、查看默认的kvm和libvirt版本

rpm -qi libvirt-daemon
rpm -qi qemu-kvm

2、KVM软件高版本仓库配置

cat > /etc/yum.repos.d/CentOS-QEMU-EV.repo <

3、libvirt高版本仓库配置

cat > /etc/yum.repos.d/virt.repo <

4、KVM软件安装

yum install -y libvirt bridge-utils qemu-kvm-ev qemu-kvm-common-ev virt-manager virt-viewer virt-install libcgroup libcgroup-devel libcgroup-tools

5、配置Libvirt软件

sed -i 's/#listen_tls = 0/listen_tls = 0/g' /etc/libvirt/libvirtd.conf
sed -i 's/#listen_tcp = 1/listen_tcp = 1/g' /etc/libvirt/libvirtd.conf
sed -i 's/#auth_tcp = "sasl"/auth_tcp = "none"/g' /etc/libvirt/libvirtd.conf
sed -i 's/#LIBVIRTD_ARGS="--listen"/LIBVIRTD_ARGS="--listen"/g' /etc/sysconfig/libvirtd

6、启动libvirt软件

systemctl restart libvirtd

7、测试libvirt软件

virsh -c qemu+tcp://localhost/system nodeinfo
virsh --connect qemu+tcp://localhost/system nodeinfo
