Yes. It's old old feature:

https://www.juniper.net/documentation/en_US/junos/topics/concept/logical-systems-overview-solutions.html

The ability to run multiple FreeBSD KVM on Linux guest is very new. It
also allows you to connect the separate instances via virtual fabric
interface, so you don't need to eat physical interface to connect the
separate instances.
This is really 100% separate JunOS, they only share the Linux
hypervisor from software POV.

Use case might be buy 128GB RE, collapse edge + pure-core without
having hardware.
Or Megaport on steroids, drop Calient optical switch in pops and MX,
have customers build via API their entire global backbone in seconds,
with active devices and optical network to connect them.

> Yeah all the costs are in edge devices, even core routers HW is order of magnitude more expensive than that of RRs

Depends, for access networks, 5 year costs tend to be dominated on
MRC's on the backhauls.
