Verifying QEMU

Prerequisites

Download the openEuler image before running the virt-install command to create a VM.

Procedure

1. Create a VM drive file in QCOW2 format.

   qemu-img create -f qcow2 /home/test1 10G

2. Create a VM.

   virt-install --name test1 --ram 2048 --vcpu=4 --cdrom=/dev/cdrom --disk path=/home/test1,size=10

   

   Parameter description:

   • name test1: VM name
   • ram 2048: size of the virtual memory
   • vcpus=4: number of virtual CPUs
   • cdrom=/dev/cdrom: path to which the OS image is mounted, for example, /home/iso/openEuler-20.03-LTS-SP1-everything-aarch64-dvd.iso
   • path=/home/test1: VM file.
   • size=10: file size, in GB.

   After verifying the QEMU component, run the virsh undefine test1 command to delete the VM used for verification.
