# HG changeset patch
# User Keir Fraser <keir.fraser@xxxxxxxxxx>
# Date 1220885523 -3600
# Node ID 1abe2bf8c0fad6efccf4be265ccfa77941fbedab

xentrace 3/7: Remove vcpu / domain from HVM traces.
This information is now redundant, as it can be determined using
runstate changes and lost record changes. This reduces log size for
long-running traces by 10-30%.
