CentOS7安裝KVM虛擬機

一.前期準備

1.確定機器有VT 終端輸入命令：

grep'(vmx|svm)' /PRoc/cpuinfo

2.確保BIOS里開啟VT:  Intel(R)Virtualization Tech [Enabled] 使用如下命令

 
二.橋接網絡
打開 /etc/libvirt/qemu/networks/default.xml 修改虛擬網卡ip
 
三.安裝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
 
讓虛擬機開機自動啟動   systemctl enable libvirtd    systemctl start libvirt
 
設置后可在/etc/libvirt/qemu/autostart下看到已設置自動啟動KVM配置文件鏈接
