#1602 duplicate Wish for better support for virtual machnines with text console Petr Slansky
Description

This is a wish for VirtualBox enhancement. Text console in guest virtual machnine can be too small on monitor with high resolution. For example, I run MS-DOS virtual machine, it has display only 25x80 character and virtual machnine output is too small to read at screen with high resolution. I cannot increse output from virtual machine, as it maps video memory of virtual machine in ratio 1:1. When I switch to full screen, I see a lo of black space and in the middle of the screnn is small arrea with virtual machine screen, in the same size; no real advantage of full screen output.

I think it can be improved, that you can (optionaly) map 1 pixel from VirtualMachine videoram to 1 (1x1), 4 (2x2) or 9 (3x3) pixels in host screen; can be configurable (auto, 1x, 2x, 3x, manual when window is resized). To implement something like magnifier. It is not difficult from my point of view.

More advanced solution will alow to have full smooth screen resizing between ratio 1x to 4x; some interpolation has to be used in this case and it will have impact to performance of VirtualMachine. From my point of view smoth resizing is not necessary.

#1603 fixed mount vboxsf filesystems automatically => Fixed in 1.6.2 Matthijs Melchior
Description

Please add code like the following to /etc/init.d/vboxvfs inside a Linux guest. This will mount and umount the 'vboxsf' filesystems mentioned in /etc/fstab whenever the vboxvfs kernel module is inserted or removed.

Thanks.

#1604 wontfix Shared Folders: Windows NT4 SP6 guest on Windows XP SP3 host. David
Description

According to the changelog:

Shared Folders: made them work for NT4 guests

But it did not work. After a fresh install of NT4 + SP6 + guest additions, the mouse integration was OK. Display enhancement was OK, but Shared Folders was not. The usual "net use X: \vboxsvr\..." command reported "System Error 53."

I clicked Control Panel -> Devices, and "VirtualBox Shared Folders" entry was there, but wasn't started. When I tried to start it, I saw this:

The C:\Windows\System32\drivers\VBoxSFNT.sys device driver could not locate the entry point ExFreePoolWithTag in driver ntoskrnl.exe"
