What tool was used to draw those diagrams?

[christophe]

Hi all,

I have to prepare a slideshow and I'm not an expert. Really.

Could someone please help me : what tool was used to build diagrams below?

They seem to all come from a same tool, each with Proxmox logo inside!

Any idea?

Thanks,

Christophe.

Where did you get them ? Perhaps ask the authors ?
