Description
I've created a VM with a clone of my webserver's configuration to test my projects under "real" conditions. The Apache webroot is a shared folder mountpoint which is connected to the folder in the host system where I store my sources for the web development.
In the guest VM, I have no problems to access the documents with cat, but the Apache doesn't deliver the files if they're larger than 255 bytes. If I reconfigure Apache to use a handler (e.g. mod_php) to process the requested file before delivering, everything works as desired.
Up to my knowledge, Apache uses mmap() for fast access to static content. Probably this mechanism needs a special support of the underlying file system which vboxvfs doesn't provide.
