(1) First of all, you need to have a CentOS virtual machine. If you don’t have one, you can refer to VMWare to install a CentOS7 operating system virtual machine to install a CentOS virtual machine.
(2 Install base commands
yum install -y net-tools
yum install -y wget
(2) Download the centos7 operating system image of the ARM architecture
mkdir -p /opt/os
cd /opt/os
wget http://mirror.nju.edu.cn/centos-altarch/7.9.2009/isos/aarch64/CentOS-7-aarch64-Minimal-2009.iso --no-check-certificate
chmod 777 /opt/os/CentOS-7-aarch64-Minimal-2009.iso
(3) The EFI
path for downloading the ARM architecture is /usr/share/AAVMF/AAVMF_CODE.fd
yum install -y http://mirror.centos.org/altarch/7/os/aarch64/Packages/AAVMF-20180508-6.gitee3198e672e2.el7.noarch.rpm
(4) Install basic dependencies
yum groupinstall 'Development Tools' -y
yum groupinstall "Virtualization Host" -y
yum install -y kvm qemu virt-viewer virt-manager libvirt libvirt-python python-virtinst
yum install libguestfs-tools -y
yum install virt-install.noarch -y
systemctl enable libvirtd
systemctl start libvirtd
usermod -aG libvirt $(whoami)
yum install virt-install virt-viewer virt-manager -y
(5) Modify the qemu configuration file
vi /etc/libvirt/qemu.conf
Uncomment the following two lines
(6) Restart the virtual machine
reboot
(7) Download qemu
cd /opt
wget https://download.qemu.org/qemu-4.2.0.tar.xz
(8) Install basic dependencies
yum install python2 zlib-devel glib2-devel pixman-devel -y
(9) Decompress qemu
cd /opt/
tar xf qemu-4.2.0.tar.xz
(10) Install qemu
cd qemu-4.2.0/
./configure --target-list=aarch64-softmmu --prefix=/usr
make -j8
make install
(11) Create a disk
rm -rf /var/lib/libvirt/images/test.img
qemu-img create /var/lib/libvirt/images/test.img 30G
(12) Start the virtual machine
qemu-system-aarch64 -m 1024 -cpu cortex-a57 -smp 2 -M virt -bios /usr/share/AAVMF/AAVMF_CODE.fd -nographic -drive if=none,file=/opt/os/CentOS-7-aarch64-Minimal-2009.iso,id=cdrom,media=cdrom -device virtio-scsi-device -device scsi-cd,drive=cdrom -drive if=none,file=/var/lib/libvirt/images/test.img,id=hd0 -device virtio-blk-device,drive=hd0
(13) Set the hostname as follows
(14) Set the network to dhcp mode as follows
