Command line to install the kvm virtual machine: yum-y install kvm qemu libvirt virt-viewer qemu-system virt-manager libguestfs-tools bridge-utils virt-install libvirt-python qemu-kvm python-virtinst yum install acpid-y / / if you want to use the virsh command, you must open the acpid service systemctl start acpid.servicesystemctl enable acpid.servicesystemctl start libvirtd.servicesystemctl enable libvirtd.service to create a bridging network Bridge mode, that is, the virtual bridge network connection mode, so that the client and the machines in the subnet can communicate with each other. You can make a virtual machine a host with a separate IP in the network. A bridged network (also known as physical device sharing) is used to copy a physical device to a virtual machine. Bridges are often used for advanced settings, especially if the host has multiple network interfaces. Add a new line at the end of cd / etc/sysconfig/network-scripts/cp ifcfg-ens33 ifcfg-br0vi ifcfg-ens33//, and remove BRIDGE= "br0" vi ifcfg-br0 from the IP-related parameters of the network card and modify the following: DEVICE=br0BOOTPROTO=static#NM_CONTROLLED=noONBOOT=yesTYPE=BridgeIPADDR=192.168.80.100NETMASK=255.255.255.0 service network restart

Before installation, set the environment language to English LANG= "en_US.UTF-8". If it is Chinese, some versions may report an error. CentOS 7 modifies / etc/locale.conf here. Mkdir-p / opt/kvm/images create a new storage pool create pre-allocated metadata options qcow2 format image file: qemu-img create-f qcow2-o preallocation=metadata / opt/kvm/images/centos7.qcow2 9G Note: create the create required to create the client,-f qcow2 means to create a disk in the format qcow2, / home/vms/centos7.qcow2 represents the disk name and disk file created 9G indicates the available size of the disk. The key to success is to select the preallocation=metadata option when creating a qcow2 mirror.
