Interesting. I haven't had an opportunity to try vMX because of its lack of
Hyper-V support, but we do run vSRX in production quite a bit including
junos versions from 17.x up to 21.x. It's kind of janky on Hyper-V but
works overall (the main issue being very very long boot times - 15+ minutes
to get up and running), but we also run it on KVM on Linux with the "vSRX3"
images, and that works a lot better. The vSRX3 images on KVM, I personally
haven't run into any issues with. The licensing costs are pretty
reasonable, too, imho.

Good luck with what you're trying to accomplish: maybe give the vSRX series
a shot if you're running on KVM.
