#1546 wontfix option to erase expandable disks Michal Suchanek
Description

The expandable disks are nice but there is no way to shrink the disk once it is expanded.

Deleting and recreating the disk image is quite annoying as it must be unregistered and re-registered with the VM.

There are two possibilities:

  • erase the disk completely - possibly an option in the config of the VM or the disk image manager - this would be helpful for test machines
  • discard zero sectors - this could be done as they are written - could be used to save space by erasing free space inside the guest OS
#1547 fixed Virtualbox incompatible with laptop power saving modes in Vista Mikael
Description

I have a Lenovo X61 tablet with Dell's Vista Ultimate 32bit. The only particular thing about its configuration is that i have the Windows XP graphics card driver installed, and the latest beta of Villagetronic's VTBook drivers for Windows Vista installed (see villagetronic.com:s sitemap, "beta download", username betatest password testbeta for that). The machine works perfectly. I run the version of Virtualbox you had as default download on your web page 10 days ago.

I run latest Debian Etch (that's Linux kernel 2.6 right?) on it.

Two bugs:

  1. When I run the machine in "Balanced" or "Power saver" mode and start my Linux virtual machine, my entire laptop crashes. The only messages i get is a partial boot in the virtualbox window, and in some instances it pops up strange DMA errors for the virtual harddrive - mostly timeouts, and once it reported a broken sector.
  1. When I hibernate the laptop while Virtualbox is running during evening, in the morning when I start the laptop, it says the laptop has recovered from a bluescreen.

Please fix these errors, as they might make users loose data!

Would you be so kind to fix this?

#1548 fixed Missing characters using serial port. Teuniz
Description

When I use the serial port in Windows XP on a Linux host, I miss characters during receiving. Serial port params are 115K2 8N1 (no flowcontrol).

This happens when an external hardware device is sending a continues datastream to the serial port at the highest baudrate (115K2). It looks likes Virtualbox is not able to handle all the data in time (empty the receivebuffer). When I use a native Linux application to receive the same data at the same baudrate without flowcontrol, no characters are missing. When I use Windows XP without virtualizing, there are no missing characters. The host is OpenSUSE 10.3.
