Sun Microsystems VIRTUALBOX VERSION 3.1.0_BETA2 - Manual (Page 238)

13 Known limitations
– OVF localization (multiple languages in one OVF file) is not yet supported.
– Some OVF sections like StartupSection, DeploymentOptionSection and In-
stallSection are ignored.
– OVF environment documents, including their property sections and appli-
ance configuration with ISO images, are not yet supported.
– OVA archives (TAR containers) are not yet supported.
– Remote files via HTTP or other mechanisms are not yet supported.
• Vista 64-bit hosts have stability issues when using USB.
• Seamless mode does not work correctly on host systems with multiple monitors.
• Mac OS X host. The following restrictions apply (all of which will be resolved
in future versions):
– No support for audio input.
– The numlock emulation has not yet been implemented.
– The CPU frequency metric is not supported.
– 3D OpenGL acceleration. In general the OpenGL support for Linux guest is
experimental. This counts especially in combination with compiz enabled
window managers. Additional we are aware of the following issues:
∗ There are several redraw problems with compiz enabled window man-
agers on Linux guests. E.g. after save/restore state or a resize of the
guest window.
• Linux hosts. There are a few problems when compiz is used as the host’s win-
dow manager, notably:
– seamless mode does not work well (garbled screen display if no windows
are open in the guest);
– OpenGL guest acceleration (added with 2.1) is very slow.
If you experience these problems, you way want to try using a different window
manager, such as metacity.
• Solaris hosts. For OpenSolaris and Solaris 10 U5/U6, the following restrictions
apply:
– There is no support for USB on Solaris 10 hosts.
– Experimental USB support for OpenSolaris/Nevada hosts (versions 124 and
higher recommended).
– No ACPI information (battery status, power source) is reported to the guest.
– No support for using wireless with bridged networking.
