In fact, I tested host<-->guest communication via vsock independently, and it works, so it does not seem a vsock issue... I also try without the series applied (but keeping patch 2) and it still fails in the same way. FTR, in the past, I've used trace-cmd from git with an earlier version of this series applied (the "KVM clock" wasn't there yet) on the same environment I'm using now, and it worked.
