Questions[virtualbox](server)

When running a vagrant instance the project folder is mounted on /vagrant automatically. However is mounted with the following permissions

# ll -d /vagrant
drwx------ 1 vagrant vagrant 612 Jun 13 14:41 /vagrant/

I need it to be mounted with (at least) 0770 but I can't find how. If I run the mount command I see this output

# mount
v-root on /vagrant type vboxsf (uid=1000,gid=100,rw)

I've tried both chmod and chown/chgrp, but they won't work on that mounted folder so my apache user can't access that folder. I read in Vagrant manual that I can change owner and group but it doesn't mention nothing about permission.

How can I do that?

Another option could be switch to NFS but in this way it won't work on Windows platforms and it need to edit local /etc/exports file and it would require root privileges and also it's pretty annoying, so I'd prefer to not make this change.

We are using Nginx to serve static files on a development platform. As it is a development platform, we'd like to disable caching so that each change is propagated to the server. The configuration of the VHost is quite simple:

server {
  server_name  static.server.local;
  root /var/www/static;

  ## Default location
  location / {
    access_log        off;
    expires           0;
    add_header        Cache-Control private;
  } 
}

When we access an HTML file (http://static.server.local/test.html), we have no issue: the server returns a code 304 Not Modified as long as the file is not changed, and a 200 OK response with the modified file when the file is changed.
However, it seems to behave differently with a Javascript or a CSS file. Once the file is changed, we get a 200 OK response as expected, but with the old text.
Is there an internal cache mechanism in Nginx that could explain this behaviour? Or some configuration that we should add?

As a side note, here is the header returned by Nginx when the file has been modified (it seems correct):

Accept-Ranges:bytes
Cache-Control:max-age=0
private
Connection:keep-alive
Content-Length:309
Content-Type:text/css
Date:Fri, 13 May 2011 14:13:13 GMT
Expires:Fri, 13 May 2011 14:13:13 GMT
Last-Modified:Fri, 13 May 2011 14:13:05 GMT
Server:nginx/0.8.54

Edit
After trying different settings with the expires directive and Cache-Controlheader, I made some further investigations. In fact, the server is installed on a VirtualBox guest Ubuntu, and data are read from a shared folder that is on the Mac OSX host.
If the file is edited from an IDE (NetBeans) on the host, it seems that changes do not appear whereas if I edit it directly on the guest (using VIM), it is refreshed.
The strange thing is it does not behave similarly with HTML files.
Quite puzzling.

Edit 2 (ANSWER)
Indeed, the origin of the issue was more on the VirtualBox side. Or rather a conflict between VirtualBox and the "sendfile" option of the server.
This link VirtualBox Hates Sendfile gave me the solution: switch the sendfile flag in the server configuration to off:

sendfile  off;

Hope this could also help other person using VirtualBox for development. :)
There are some additional information on the VirtualBox forum.

I was wondering if someone could give me a simple guide on how to set up virtual networking in VirtualBox (4.0.2) so that the following scenarios work:

• Both Host and Guest can access the Internet
• Host can ping Guest and vice versa
• Host can access, for example, an apache web server running on Guest and vice versa

I've been fiddling around with the various Network Adapters available in the settings for my Guest, but I'm just not able to figure it out. Is there anyone that can help me out here?

The host is running Windows 7 32-bit and the guest is running Ubuntu 10.10 32-bit.

I have VirtualBox set up on a server. It was set up as a Bridged VM, and has an IP address. It's now running in headless mode, started with "VBoxHeadless -s PuppetMaster".

How can I find out what IP the VM is using VBoxManage?

Is there any way to create a virtual machine that you can use in VirtualBox from a physical installation that you have? For instance, if I have Windows XP installed on a physical computer and want to have a virtual version of that machine on a different computer. This would save a ton of time by not having to reinstall and reconfigure the whole OS.

I would think there would be issues with Microsoft's licensing. But even if it's not possible with Windows would it be possible to take a physical Linux machine and create a VirtualBox version of that? Does any other desktop virtualization software provide this feature?
