VirtualBox: Can't copy files to a shared folder under ArcaOS guest

<< < (4/4)

Neil Waldhauer:
I'm also confirming the shared folders are working here.

When I upgraded my Windows 11 host system to VirtualBox 7.20, no errors were found, but I could not start my ArcaOS 5.1.1 virtual machine. I restarted a few times, and eventually it ran, so I updated OS/2 Additions and tested shared folders.

I had the same EA issue as Martin, but that is acceptable for me.

Dan Eicher:
I had a learning experience.

Logged in as admin user and install Virtualbox 7.2 (was on 7.1)

Started Virtualbox, no VM.

After a bit of back and forth, I had to user powershell to generate a new UUID, then change the UUID in the .vbox file.
Then re-register the VM.

Virtualbox, was apparently upset that the UUID of the VM was already registered, even though it was not showing in the inventory, upon starting after the upgrade. 

IDK, your mileage my vary.

David McKenna:
Hi Martin,

  With a Windows 11 host, I have 2 shared folders - one on a FAT32 drive and one on an NTFS drive. I only get that message you show in ArcaOS on the folder on the NTFS drive. I have the /eas switch on my FAT32.IFS line in CONFIG.SYS so seems that takes care of it there? I don't know of any way to get rid of that message, but would also like to know how (if possible). Wonder if there are any switches for the VBoxSF.ifs driver that would do it....

Regards,

Dave Yeo:
On NT, FAT32 won't support EA's, FAT actually does (might have to be formatted on OS/2). NTFS does have a stream dedicated to OS/2 EA's, even supports codepages unlike a normal stream or file on NTFS which use UTF. Unless MS has removed support.
I'd guess vbox itself fails to transfer the EA's.
On Linux, only some file systems support EA's, or as they call them, xttr's and it has to be turned as a mount command. Ext4 for example only supports 4kb xttr's, others such as JFS support 64kb or more. I notice on Mint, mounting an OS/2 JFS partition doesn't seem to enable xttr's, though it does mount them as case insensitive as it should.
