The is a virtualised version of the QFX10000 data centre switch. Juniper offers it free of charge to customers and partners, though it is not formally supported. It replicates the same control plane and data plane features as the physical hardware, with the obvious limitation that virtual forwarding performance is lower than dedicated ASICs.
This is a separate VM (often running a different light software layer or packet forwarding engine like Cosmo/Cosim) that simulates the hardware ASIC. It handles the actual data plane traffic traveling between virtual ports. vqfx202r110reqemuqcow2 exclusive
