Xml file

Attention: 1. When setting up memory, pay attention to the writing of unit. 2. The path of emulator, written on one line 3. Can write without line, a label, try to write on a line 4. Use qemu-img management tools to create virtual machine files, for example: qemu-img create-f qcow2 test.qcow2 10G 5. The created file does not have permission, so you need to change the created virtual machine file to the user group sudo chown hgf:root / var/lib/libvirt/images/test.qcow2. That is, under the name of the user who executed the start

Centos 1024 1024 2 hvm destroy restart destroy / usr/libexec/qemu-kvm Define a virtual machine

Virsh define test_virsh.xml

Use virsh undefine [virtual hostname] to undefine virtual machines

Start the virtual machine

Virsh start cetos

The parameters after start are specified by the name tag of the virtual machine previously defined with xml, or after the define virtual machine, use the command virsh list-- alll

Vnc View Virtual Machine

Query the vnc port virsh vncdisplay centos used by the virtual machine

Vncviewer installation

Yum install vnc (Anza ungde is tiger vncviewer) after opening vncviewer, enter the IP address: serial number in the address bar, such as 127.0.0.1 tiger vncviewer 0

Note: the serial number here is queried using the virsh vncdisplay hostname
