virsh list # 查看运行的虚拟机
virsh list --all # 查看所有的虚拟机（关闭和运行的虚拟机）
virsh shutdown online-110 # 关闭主机
virsh start online-110 # 开启主机
virsh auotstart --disable online-110 # 取消自动启动
virsh destroy online-110 # 删除虚拟机
virsh undefine online-110 # 解除虚拟机标记
复制配置,新建虚拟机:
cd /etc/libvirt/qemu
cd /home/kvm/images
vi /etc/libvirt/qemu/online-110.xml # 修改主机名,uuid, 机器码,source file,mac address
virsh define /etc/libvirt/qemu/online-110.xml
virsh shutdown online-110 # 关闭主机
virt-edit -d online-110 /etc/sysconfig/network-scripts/ifcfg-eth0 # 修改配置
virt-edit -d online-110 /etc/sysconfig/network
virt-edit -d online-110 /etc/hosts
virt-edit -d online-110 /etc/resolv.conf
virsh start online-110 # 开启主机
增大虚拟机内存、增加虚拟机CPU个数需要首先关机虚拟机: # 调小配置,不用关机.
virsh dominfo daily-117 # 查看配置信息
virsh shutdown daily-117 # 关机
virsh edit daily-117 # 编辑配置
