windows guest - linux host file permissions changed on shared folders -> Fixed in SVN

virtual box log during permission change

another log with the same file permissions alteration

I'm just updated for VBox 3.0 and I'm facing the same issue. I didn't find problems with other applications yet, except MS-Office suite (which are taking too long to read the files too).

Just to be clear, I can save the file only once. After this, the permission is changed and I have to restore it before saving again.

A note on the problem:

If you have an instance of Nautilus/Dolphin open to the directory your file is stored in; at the time of file modification/save the permissions do not get changed. Pablo could you try this and verify? I tried with MS word, Excel and visual studio, all MS products. I'll try doing it with a non MS product, to verify.

As noted this happens in Gnome2.26.1 and KDE4 vbox 3.0.0

A note on the problem: clarified.

If you have an instance of Nautilus/Dolphin open in your "HOST OS" to the directory your file is stored in; at the time of file modification/save in your "GUEST OS" the permissions do not get changed. Pablo could you try this and verify? I tried with MS word, Excel and visual studio, all MS products. I'll try doing it with a non MS product, to verify.

As noted this happens in Gnome2.26.1 and KDE4 vbox 3.0.0

I confirm this bug. I have it in Ubuntu 9.04 host and WinXP guest. http://www.virtualbox.org/ticket/4390[[BR]]

Same behaviour on Ver 3.0 Host: Fedora 9 Guest: W2K

copy with Explorer creates 664 copy with totalcommander creates 400 - delete of the files from totalcommander is possible copy with cmd creates 400 - delete of the files from cmd is possible

I reposted it from a closed ticket #2592.

I tried with Nautilus opened and got the same problem. My host is Ubuntu 8.04, with Gnome 2.22.3, with guest WinXP SP3.

me too! Vbox 3.0 | Host: openSUSE 11.1 KDE 4.2 | Guest: WinXP SP3 Problem occurs with all MS Office 10 / 2007 products in the way described.

Confirming on Ubuntu 9.04 host with Windows XP SP3 guest. Virtualbox 3.0.0 r49315

Thanks everyone for reporting the problem. The fix will be available in the next VBox version.

Lovely. I can't want and am going back to VBox 2 immediately. I hope the config files are still compatible.

BTW I had a problem almost exactly like this in VirtualBox before, it got fixed ages ago so this is a regression. Times like this I think virtualbox is all a sly plot to make people buy VMWare Workstation. Something critical breaks in every release - I haven't dared find out whether the clipboard sharing works.

I think I solved the problem then by using Samba and connecting to a network drive. If Samba can map permissions correctly, vbox should be able to use the same rules.

Incidentally, normal readonly files (from when I was using VBox 2.2) have permissions 444. Attempting to REMOVE readonly attribute appears to change to 400 (not the expected 666) the ATTRIB command couldn't fix this.

I just downloaded the latest 3.0.6 r52128, having encountered this issue, and it's still there. So it's either been regressed again, or hasn't been fixed. It's really frustrating when you can't run apps that write to shared storage.

Which application do you use to save files to shared folders? And please attach VBox.log of the VM.

Replying to sunlover:

I'm trying to test an Apache Pluto server, but surely the application is irrelevant - opening the folder in Explorer shows the status as read-only, and the only way to get anything to write into the folder is to create the files first in Explorer.

Windows 7 guest

Hi, I'm experiencing similar problems with windows XP and Windows 7 (Ubuntu 9.10, VB 3.10). I can make folders and files myself, and deleting them is also not a problem.

But I have e.g My scanner software running in VB. Scanning works fine, but as soon as I try to save it, it simply refuses to write the files on the specified folder.

Same for my java written software; In order to work properly it needs to write some files in normal, by the software created folders. These folders and files are never created by the software and therefore I get a "File not found" exception later on.

It doesn't matter if I have the software running in eclipse, or as stand alone.

Hope you know a fix for the problem. Thanks, scaary

Win XP Home x86 guest on Karmic host - can't unset read perms on folder in share

Also can confirm inability to of an app to write to a folder in a shared dir. Host is Linux (Karmic, 2.6.31-17-generic x85_64) from XP guest. However, when I manually create a new file in that dir, it seems to work. Only the app has trouble, saying in a popup that it needs write permission to the folder. The logged-in user on the guest is an admin. Also tried running the app as current user but with 'protect' unset.

Each attempt to unset read only perms in the file properties on the guest is ignored.

Also is the "fixed in SVN" portion of ticket title still valid?

poppafuze, which application fails to write to a shared folder?
