To be clear, Inferno is the operating system. The virtual machine is Dis. There exist a few examples[1] of 64-bit Dis, but usually the problem people run into is making the Limbo[2] compiler spit out 64-bit code.
It's rather unfortunate, Inferno is a really nice system with a lot of interesting reference stuff implemented like a typed shell[3]. It's also Plan 9 in a box with all the accoutrements, and knowers will have jumped out of their seat at the implication. I can't understate how cool the Inferno system is.

I dunno what happened to the 64bit port, the author just up and deleted it with no reason given AFIK. Thankfully someone had a recent clone and uploaded it to the archive.
Limbo is incomplete, forget what exactly but a few people on the 9fans discord recently ran into issues. Always remember, Inferno was forced onto the Labs people by Lucent in an attempt to compete with Sun's Java and built in a year. Bell Labs did not do marketing and Lucent fumbled the whole thing.
Plan 9 in a box is only useful if you MUST use a foreign host like Linux. Otherwise I would much prefer the machine actually run Plan 9.
