linux + cisco virtual environment?

Question

linux

Good day,
tell me which virtual environment to choose in order to deploy a couple of switches, routers and linux hosts,
and so that the computer does not melt.
I would also be very grateful for advice on which switches and lightweight router to choose and where to download images for them.
I would be very grateful!
