* Perf for only one VM? @ 2011-10-05 19:54 Robin Lee Powell 2011-10-05 22:03 ` David Ahern 0 siblings, 1 reply; 3+ messages in thread From: Robin Lee Powell @ 2011-10-05 19:54 UTC (permalink / raw) To: kvm Is it possible to get perf kvm record to record only what's going on on a single VM? The options seem to be --host (all host data) and --guest (all VM data). I'm getting " 74.86% qemu-kvm [unknown] [u] 0x7f3795bc408d", and I think that's because I've got kallsyms loaded from a particular guest, but not the others. -Robin ^ permalink raw reply [flat|nested] 3+ messages in thread
