VMware GSX Server supports a partial emulation of bidirectional PS/2-style ports.

On Linux hosts, GSX Server requires that the parallel port "PC-style hardware" option (CONFIG_PARPORT_PC) be built and loaded as a kernel module (that is, it must be set to "m"). GSX Server is unable to use parallel port devices if CONFIG_PARPORT_PC is built directly (compiled) into the kernel. This limitation exists because CONFIG_PARPORT_PC does not correctly export its symbols.

The following sections describe how to use parallel ports with GSX Server:
