It's also needed to correlate over different guests on the same machine. This is an important use case. It would be nice if we could find a way to export the per guest TSC offset from KVM, then we could use the more reliable TSC for this, at least as long as no TSC scaling is used. But failing that wall clock is probably the best you can do. -Andi
