systemctl start libvirtd

systemctl enable libvirtd

.创建虚拟机

virt-install --virt-type kvm --name test01 --ram 1024 --vcpus 1 --cdrom=/home/kvm/CentOS-7.0-1406-x86_64-DVD.iso --disk path=/home/kvm/test01.qcow2,size=10,format=qcow2 --network bridge=br0 --graphics vnc,listen=0.0.0.0 --noautoconsole --os-type=linux --os-variant=rhel7


.连接道virth

virsh --connect qemu:///system
.virt-viewer
    连接本机的虚拟机:virt-viewer -c qemu:///system 虚拟机名
    连接远程的虚拟机:virt-viewer -c qemu+ssh://ip/system 虚拟机名

设置开机自启动 virsh autostart server01
