From f51304d3fe4fee475991ee424a4b7f85eec65a7b Mon Sep 17 00:00:00 2001 From: David Ahern Date: Fri, 20 Jul 2012 17:25:46 -0600 Subject: [PATCH] perf symbols: Add machine id to modules debug message Current debug message is: Problems creating module maps, continuing anyway... When running multiple VMs it would be nice to know which machine the message is referring to: $ perf kvm --guest --guestmount=/tmp/guest-mount record -av -- sleep 10 Problems creating module maps for guest 6613, continuing anyway...
