We're seeing rather similar symptoms on Launchpad builders after upgrading the guests from wily to xenial (console-log not very informative, e.g. https://pastebin.canonical.com/160898/plain/; build output appears hung; I can't tell for sure that it's the same thing, this is just a guess). These are on the same scalingstack hosts as Martin is using, so if anything the surprise is that we weren't seeing it before (we had different problems, mainly occasional hangs on boot). KVM is enabled, host is 4.2 per Junien's comments above, only interesting kernel parameter we're using at present is "compat_uts_machine=armv7l".
