-# QEMU base image creation
-
-This folder contains scripts and configuration to create a QEMU virtual drive with a debian system.
-
-The order of execution is:
-- `init.sh` to download the installation kernel and ramdisk
-- `preseed.sh` to preseed the debian installer so it doesn't ask questions 
-- `copy.sh` to extract the kernel and ramdisk from the installed system
-- `run.sh` to boot the system and fine tune the image
-
-# Description of the process:
-
-# Preparing the base image
-
-First, an installation is made using installer kernel and initrd by using the scripts above.
-
-# After installation, we extract initrd and kernel from the installation drive
-
-The commands look like this:
-
-`virt-copy-out -a hda.qcow2 /boot/initrd.img-4.15.0-30-generic-lpae .`
-
-In the same way for the kernel.
-
-Then we install packages and dependencies on the qemu image:
-
-apt install -y sudo python3-dev virtualenv wget libgfortran3 libopenblas-base rsync build-essential
-libopenblas-dev libomp5
-
-We enable sudo and passwordless logins:
-
-Add file `/etc/sudoers.d/01-qemu`
-With content:
-```
-qemu ALL=(ALL) NOPASSWD: ALL
-```
-
-Edit: `/etc/ssh/sshd_config`
-
-And set the following options:
-```
-PermitEmptyPasswords yes
-PasswordAuthentication yes
-PermitRootLogin yes
-```
-
-Disable root and user passwords with `passwd -d`
-
-Edit ` /etc/pam.d/common-auth`
-
-Replace `auth    [success=1 default=ignore]      pam_unix.so nullok_secure` by 
-```
-auth    [success=1 default=ignore]      pam_unix.so nullok
-```
-
-As root to install system wide:
-
-```
-wget -nv https://bootstrap.pypa.io/get-pip.py
-python3 get-pip.py
-apt-get clean
-```
-
-Afterwards install mxnet python3 deps:
-
-```
-pip3 install -r mxnet_requirements.txt
-```
-
-
-To access qemu control console from tmux: `ctrl-a a c`
-
-# CI and Testing
-
-Formally, [runtime_functions.py](https://github.com/apache/incubator-mxnet/blob/master/ci/docker/qemu/runtime_functions.py) would [run](https://github.com/apache/incubator-mxnet/blob/8beea18e3d9835f90b59d3f9de8f9945ac819423/ci/docker/qemu/runtime_functions.py#L81) *pip install -r [mxnet/tests/requirements.txt](https://github.com/apache/incubator-mxnet/blob/master/tests/requirements.txt)*. If the requirements change, there can be an unfortunate side-effect that there are no wheel files for Raspberry Pi for the new requirement. This would trigger a build from source on the emulator, which can take a long time and cause job timeouts. Therefore, we no longer install the `tests/requirements.txt` requirements, but rather rely on [test_requirements.txt](https://github.com/apache/incubator-mxnet/blob/master/ci/qemu/test_requirements.txt) to maintain the requirements for the qemu tests. Should any requirements changes lead to a job time out, it is incumbent on the submitter to update the image to include the requirement and unblock ci.
