dtrace discuss - Jul 2009 - tick provider not happy under virtualbox?

Hi,

I was putting together a script to format and print some aggregations.  In
developing/testing I was running OpenSolaris 2009.06 VirtualBox on MacOS.  The
tick provider didn''t seem to be firing regularly, so I tried a quick
oneliner once a second, which confirmed they''re not firing as expected.

I just tried on the metal and it works as expected, as does a Xen DomU. 
I''d imagine if this didn''t work correctly, the Sun Storage
Virtualbox simulator would have serious issues too.

A quick search of bugs (solaris/kernel for "category" and
"dtrace" for subcategory) didn''t turn up anything.*  Neither
did searching the DTrace wiki on wikis.sun.com for VirtualBox turn up any notes
or a quick scan of the performance and stability chapters.

Sorry to be the problem child for this list of late.

* the bug search from bugs.opensolaris.org shows the category as
"evemt_ports/kernel (Solaris Fault Management Architecture)" even
though that''s clearly not what I put in there... I hope it''s
actually doing the right thing...
