Cannot create the virtual disk on NTFS partition

[quanta]

Hi,

I asked in the forum but no reply in 3 days therefore I open a ticket here.

As I mentioned in the title, when I create the virtual disk on the NTFS partiton which was mounted with write permission, I got the below error:

Failed to create the hard disk storage /mnt/data/VirtualBox/win2k8.vdi.
Could not create the hard disk storage unit '/mnt/data/VirtualBox/win2k8.vdi'.
VDI: writing pre-header failed for '/mnt/data/VirtualBox/win2k8.vdi' (VERR_NET_OPERATION_NOT_SUPPORTED).

Result Code:
NS_ERROR_FAILURE (0x80004005)

My NTFS partiton was mounted with write permission:

/dev/sda6 on /mnt/data type fuseblk (rw,nosuid,nodev,noatime,allow_other,blksize=4096,default_permissions)

$ ls -ld /mnt/data/VirtualBox/
drwxr-xr-x 1 quanta quanta 48 Feb 22 14:56 /mnt/data/VirtualBox/

The vboxdrv module was loaded in running kernel:

$ lsmod | grep vbox
vboxnetflt             11304  0
vboxnetadp              5692  0
vboxdrv               114736  2 vboxnetflt,vboxnetadp

Below is different result code when I upgrade to version 4.0.4:

Result Code:
VBOX_E_FILE_ERROR (0x80BB0004)

Does anyone think of any reason for this?

Please attach the whole VBox.log file for that case. After that, please enable the host cache for this .vdi file located on an NTFS partition and try to boot the VM. Does that work?

[quanta]

Because my .vdi file was not created therefore there is no VBox.log file in ~/.VirtualBox/Machines<vm name>/Logs. The strange thing is win2k8 folder was created in ~/.VirtualBox/Machines, but contains nothing:

$ ls -la ~/.VirtualBox/Machines/win2k8/
total 8
drwxr-xr-x 2 quanta quanta 4096 Feb 28 09:20 .
drwxr-xr-x 4 quanta quanta 4096 Feb 28 09:20 ..

and it disappears when I click the OK button on the above error dialog and Cancel button on the "Create the virtual disk" dialog.

$ ls -l ~/.VirtualBox/Machines/
total 4
drwxr-xr-x 3 quanta quanta 4096 Feb 27 22:53 TinyXP

I also try to create 2 folders HardDisks and Machines in /mnt/data/VirtualBox, but it seems that VirtualBox didn't care about them.
