Odd file permissions in files created by Host

[Brad Condo]

I have noticed some odd behavior in relation to shared folder files when viewed on an Ubuntu 11.10 guest and a Mac OSX 10.7.2 host in Virtualbox 4.1.6.

I am using my guest as a LAMP development server, and if I attempt to access a file via Apache running on the guest that does not exist and the subsequently create the file on the host, the file is inaccesible in the guest. A screenshot is attached of a basic ls command on the guest.

I should also mention that rebooting the guest fixes the issue and the file is then accesible as expected.

I am experiencing the same issue with OSX 10.6.7 as the host OS and Ubuntu 11.10 as the guest.

It also doesn't seem to matter if the files were created by the guest or host, they can end up unreadable on the guest either way.

As mentioned above, rebooting the guest seems to fix the issue.

I wonder if Ubuntu 11.10 is a common thread here. I'm having the same problem:

• Mac OS 10.7.3
• VirtualBox 4.1.8
• Ubuntu 11.10

I have not seen this problem on Ubuntu 10.04 VMs.

This bug is still happening:

• Mac OS 10.7.3
• VirtualBox 4.1.14
• Ubuntu 12.04 server

I originally suspected Ubuntu 11.10 as a common link, but it's happening with the new version too. (Previously we were running 10.04 and didn't see the bug there.) See ​https://forums.virtualbox.org/viewtopic.php?f=3&t=46021 for a screenshot showing the problem.

I also experience this bug:

For me I'm not attempting to access via apache first. I am creating the files in the NetBeans IDE (project resides in the shared folder). I do, however, experience exactly this issue where the file is unreadable by the guest.

• Windows 7 Host
• VirtualBox 4.1.14 & 4.1.16
• Fedora 16 Guest

We still need a simple scenario to reproduce this problem. So far I see only Mac OS X hosts and Windows hosts are affected, also Linux hosts?
