VBox 2.1.0 on Solaris constantly opening iconv shared objects

描述

A VirtualBox Windows 2003 guest performing a Visual Studio build on a shared folder is taking many times longer than the same build on a "local" guest filesystem.

Truss'ing VBox while this is happening shows the VirtualBox process repeatedly opening shared objects related to iconv() (every 100 uSec or so!). At bottom of this report is output from "truss -D -t\!all -topen -p <vbox-pid>".

# truss -D -t\!all -topen -p 8225

This is normal for converting filenames from one codeset to another.

Actually this will be fixed in the upcoming release 3.2.0.
