Persistent Virtual Machine

Grid'5000 infrastructure may provide one persistent virtual machine to each user.

Such a VM runs inside the Grid'5000 network and is available permanently (i.e. it is not required to have an OAR job running).

It has the following specifications:

• 1 vCPU
• 2GB of RAM
• 8GB of disk space (see below if more is required)
• An address in the form <username>-vm.<site>.grid5000.fr
• Debian "stable" operating system
• No direct network access from the outside of the Grid'5000 network (but SSH tunneling, VPN or reverse HTTP proxy are possible, just like for nodes)

Upon the creation of your VM, you will be able to connect to the VM using SSH as root, from the Grid'5000 network. Thus, you will have full privileges on the machine, and will be able to modify it as it pleases you.

Terms of service

• No backup of the VM disk will be provided by the Grid'5000 team
• The Grid'5000 team will not provide assistance to manage your VM (software installation, configuration, security updates if relevant...)
• ... but you can contact the Grid'5000 team if you encounter an issue that prevent you from using your VM (lost access to the VM, unusual poor performence, ...)
• The location of the VM might have to change (due to hosting concerns), thus the Grid'5000 site where your VM is hosted must not be considered immutable.

	Note
	In a first phase at least, this service may be provided thanks to recycled service machines, which might have higher failure rates. The backup of any sensible data is of your responsibility. Also it will not be possible to choose what Grid'5000 site will host your VM.
