Apache running under VirtualBox does not give some files when connecting from the host side

Question

Apache HTTP Server

Environment, just in case:
Apache 2.2.20 is running on Ubuntu server 11.10 x86 under VirtualBox 4.1.4 Host - Win7 x64.
Between axes the network bridge is raised.
DocumentRoot for Apache under Ubuntu is a mounted directory, which is a directory with files for wines (shared using VirtualBox).

Problem:
when you try to open one of the projects, some of the images in it are not loaded. And the other - having exactly the same address, only the file name is different - is loaded. That is:
servername/project/templates/default/images/userpic.png - not loaded
servername/project/templates/default/images/new.png - loaded
At the same time, all files, of course, are in place. The rights are correct everywhere.
Here's what's in the Apache access.log: At the same time, Apache gives all the files correctly if the request is local Oh yes, just in case: I cleared the cache :-)

192.168.0.111 - - [07/Nov/2011:03:50:35 +0400] "GET /project/templates/default/images/new.png HTTP/1.1" 200 511 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.106 Safari/535.2"

Answer 1

I recently dealt with this topic. After long tests, I found the problem in the VirtualBox extensions. When Apache works through mounted virtual directories, it gives files to some kind of broken ones, I could not fix, read or perform other actions - everything rests on virtualbox.
(as I understand it, you need more space for hosting)
I had 2 solutions:
1) create another VHD with a large partition and upload it there.
2) create a true network folder, and mount it through a network bridge bypassing virtualbox. (didn't test it, but I'm sure it would work)
I chose the first option, since I have a high degree of supervisor security and I reject any requests from virtual machines.
PS: Bring a friend))). I have an absolutely identical system of work on my home server, except that I have debian and wines. dreampark server.

Answer 2

For a very long time, the code of the built-in SMB server (through which the built-in file sharing of the host system inside the guest system is organized) is crooked and buggy, bugs hang for years and are not fixed. It's all about data caching, as I understand it.
The best advice I can give is to not use this mechanism.
ps if you have linux in the virtual machine, guest windows - try going to colinux.org
it is based on user mode linux technology, when no processor virtualization occurs, and the equipment is emulated through the colinux kernel ... what am I talking about? the local built-in folder sharing mechanism was not buggy for me a year or two ago.
Linux itself is transferred stupidly backup / restore. of the shortcomings, xorg is needed for windows (there are ready-made portable colinux assemblies)

Answer 3

How is the network configured between host and VM? The assumption is purely from the category of telepathy, but I see a problem with MTU.

Answer 4

I use a bunch of VirtualBox (Ubuntu Server 10.04 LTS) on Win7 x64. 2 interfaces are raised on the virtual machine: NAT and HostOnly
I keep all project files in the virtual machine, and I access them from Windows via Samba.
IMHO, the most “correct” way in terms of the absence of hemorrhoids and, as a bonus, it’s convenient to backup.

Answer 5

If problems with VirtualBox cannot be solved, I advise you to try colinux. There is a ready-made debian image for it, in which you can easily deploy everything you need. And it will be faster.

Answer 6

I advise you to look here httpd.apache.org/docs/2.0/mod/core.html#enablesendfile
For NFS or SMB mounted files, this feature may be disabled explicitly for the offending files
