dtrace discuss - Dec 2009 - dtrace and OpenSolaris within VirtualBox

Hi,

I want to introduce performance analysis / OS performance diagnosis using
DTrace within OpenSolaris. However, my Institutes computing "support"
people
are reluctant to set up a dual boot OpenSolaris/ Windows configuration and
prefer instead for me to use OpenSolaris within VMware or VirtualBox.

My question is: how reliable and insightful would the DTrace stats and
results be if the OS was running in a virtual environment? Do the Windows
kernel stats map well or 1:1 with what gets collected by DTrace
inside OpenSolaris?

Thanks for any help on this.

John

It runs well. You can expect system, applications and a lot of other stuff. But
sometimes it looks like it''s slower under VirtualBox.
