A jail breakout, it being from a process namespace or a VM, is always a security-risk - whatever it's breaking out of. Both are sensitive to this. VM's are maybe a bit more mature and handle some stuff on hardware - but given the recent Intel oops thingies - I wouldn't rely on that too much...

"Containers are less secure" is just FUD. That VM's or containers alike are running on the same CPU is currently a much more real threat.
