CentOS7安装KVM虚拟机
一.前期准备
1.确定机器有VT
终端输入命令：
grep'(vmx|svm)' /proc/cpuinfo
2.确保BIOS里开启VT: Intel(R)Virtualization Tech [Enabled] 使用如下命令
lsmod | grep kvm modprobe kvm-intel
二.桥接网络
打开 /etc/libvirt/qemu/networks/default.xml 修改虚拟网卡IP
三.安装kvm
yum -y install libcanberra-gtk2 qemu-kvm.x86_64 qemu-kvm-tools.x86_64 libvirt.x86_64libvirt-cim.x86_64libvirt-client.x86_64 libvirt-java.noarch libvirt-python.x86_64 libiscsi-1.7.0-5.el6.x86_64 dbus-devel virt-clonetunctl virt-manager libvirt libvirt-python python-virtinst
让虚拟机开机自动启动 systemctl enable libvirtd systemctl start libvirt
设置后可在/etc/libvirt/qemu/autostart下看到已设置自动启动KVM配置文件链接
