I don't believe we've ever seen this in VMs. The main place excessive kernel output has been problematic is on scalingstack compute nodes, which are mostly HP ProLiant DL360p Gen8s (AMD64) and HP ProLiant m400s (aka. mcdivitt, ARMv8). Both have a virtual serial port exposed by the BMC or chassis, and kernel messages go to that. But the machines run VMs -- they're not themselves virtualised.
In the DL360p case we get CPU hangs, while in the m400 case we get excessive memory consumption.
