13Known limitations

–OVA archives (TAR containers) are not yet supported.

–Remote files via HTTP or other mechanisms are not yet supported.

•Host-only networking. Creation/deletion of host-only adapters are supported for Windows hosts only presently. On other platforms, there is one fixed host- only interface called “vboxnet0” presently. This will change in a future release.

•Vista 64-bit hosts have stability issues when using USB.

•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:

∗OpenGL windows aren’t updated in the Dock Icon real time preview.

∗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.

∗OpenGL host support is not yet available on 64-bit kernels (Mac OS X 10.6).

•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. On other supported Solaris systems (OpenSolaris and Nevada), support is experimental. USB device filters do not work at all.

–No support for audio input.

–Only experimental USB support for OpenSolaris/Nevada hosts (versions 109 and higher recommended).
