VMSetError: VirtualBox can’t operate in VMX root mode.

VirtualBox failed to start VM guest on OEL5 node,

To Workaround:

where is the whereis

Today when I’m applying some scripts on Solaris 11Express nodes, a interesting error comeup,

As on Solaris 10, we use cmd whereis(/usr/ucb/whereis) as a standard component.
(On Linux, it’s also a part of the util-linux-ng package )

Solaris 11X doesn’t include this command in default set, so turn to documents for help:

<Oracle Solaris 11 ISV Adoption Guide>

Very lucky the command whereis is the rest  for kept in compatibility/ucb package as optional.
But it’s no longer suggested to use such cmds in further SOLs, I finally gave up refresh the toolkits.

Oracle Solaris 11 ISV Adoption Guide
Solaris 11 Express Changes: Where is /usr/ucb ?
*this arc shows the discussion on some port specific /usr/ucb commands,
the abandon of those codes speed up the far and away of those BSD like code.

From this point, SOL’s running faster than Linux….
