Hello,

I am running VM on Mandriva host. My guest is a Win XP.
I am trying to use the floppy under XP but each time I activate floppy, the VM blocks with error message:


Cannot open host device '/dev/fd0' for read/write access. Check the permissions of that device ('/bin/ls -l /dev/fd0'): Most probably you need to be member of the device group. Make sure that you logout/login after changing the group settings of the current user (VERR_ACCESS_DENIED).
Unknown error creating VM (VERR_ACCESS_DENIED).


Code de résultat :
NS_ERROR_FAILURE (0x80004005)
Composant :
Console
Interface :
IConsole {e3c6d4a1-a935-47ca-b16d-f9e9c496e53e}

I verified that the user is correctly configured in vboxusers and floppy groups.
I verified that /dev/fd0 is rw accessible.

Could anyone advise me some checks or configurations ?

Thx

Is the floppy mounted in the host?
If so umount it.

Hi Baf,

Thx for your answer.
I checked twice. Floppy is not mounted on mandriva host. The entry /dev/fd0 is present in /etc/fstab but not mounted.

When I start my VM (with floppy activated), I can see the light of the floppy drive which is lit constantly... Is that a clue ?

Thx

I've got more or less the same problem, but haven't find a solution yet.

I have an openSUSE 11.1, and two guests (a Windows XP and an MS-DOS). None of them can access the floppy drive (/dev/fd0), though permissions are OK.

However, the VM doesn'block nor I get any error (excepting that of the guest system telling it can't read the floppy).

I tried floppy once too a while ago, just for a test. I noticed that I had to have to floppy mounted in the Host. I found that strange, but it was the only way to get it working. Sort of. Swapping the floppy, remounting it every time didn't help much to keep it working.

I haven't used the floppy in over a year, but last time I tried with VB I found it worked much better for me to create .img images of the floppy, and mount the images instead of the actual floppy.

If I remember correctly, this is what I did:

1) insert floppy into drive
2) on the host, open up a shell
3) use the command: cat /dev/fd0 > disk1.img
4) repeat steps 1-3 for all floppies you'll need in VB

Then in VB, bring up the "Devices->Mount Floppy" window and add/select the .img file you need to mount.
