Today I set up CentOS by using Google Cloud Platform, which is so amazing services, before I make device driver. below is draft to set up it.
1.You have to install Google Cloud SDK from this url(http://qiita.com/yuko/items/aaac6ea9536cd529106f) in order to use SSH on Shell(in my case Mac 10.6) But, You need Python2.7, so if your mac is under 2.6, you first have to install it from this url(https://www.python.org/download/).
2.You have to make account from this url(https://cloud.google.com/?hl=ja)
4.You can access CentOS via SSH
If you want SU, just do 'sudo -s' (http://www.cyberciti.biz/faq/google-cloud-compute-engin-ssh-into-an-instance-from-linux-unix-appleosx/)
5.When you want to finish the instance(CentOS), you have to gcutil deleteinstance(https://developers.google.com/compute/docs/instances?hl=ja#stop_job)
Below is sample of Driver's code
There is "kernel.h" instead of "stdio.h" It indicates that it can use a kernel space.
