Installing QEMU

QEMU needs to be installed only on the host.

1. Install the compilation dependencies.

   yum -y install gcc make glib2-devel zlib-devel pixman-devel libaio-devel flex bison

2. Download the code library from the Kunpeng community.

   1	git clone https://github.com/kunpengcompute/qemu.git

3. Switch the branch.

   1 2 3

   cd qemu git checkout stable-4.0 git submodule update --init

   

   On CentOS 7.6, git submodule reports the following error:

   error: RPC failed; result=22, HTTP code = 422

   You are advised to compile and install Git 2.x.

4. Create a build directory and go to this directory.

   1	mkdir build && cd build

5. Perform compilation and installation.

   1 2	../configure --target-list=aarch64-softmmu make install -j 16
