#12384 obsolete Bad working mouse capture with some screens Mrowqa
Description

Step:

  1. Start a VM without mouse guest os integration.
  2. Move VM window to other screen (I moved to left of main screen)
  3. Press host key.

Expected result: Window with VM captures mouse cursor. Real results: Mouse cursor is set on position (0,0) globally in system instead in VM window (probably VBox doesn't check if there are some screens with negative x's positions). Now mouse cursor is not captured and you can move cursor over widnow with VM, but it work's strangly - cursors have another speed (DPI).

#5169 fixed Bandwith from Host to Guest limited by the real ethernet mounted on host. Giovanni Toraldo (gionn)
Description

virtualbox-ose 3.0.6-dfsg-1~bpo50+1 (debian lenny-backports)

I caught a behavior that I wasn't expecting

I have a Debian Lenny amd64 host with a gigabit network card but, unfortunately, attached to a 10/100 switch: 02:00.0 Ethernet controller: Attansic Technology Corp. L1 Gigabit Ethernet Adapter (rev b0)

I setup a Debian Lenny i386 guest with a gigabit network card: 00:11.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 02)

I was hoping that between host and guest, i will get full gigabit speed, but instead, I've host outgoing bandwidth limited by *real* speed.

Here the output of two iperf sessions:

Host -> Guest

[  4]  0.0-10.0 sec    382 MBytes    320 Mbits/sec

So, it's the outgoing data from host to guest passed to the wire before getting into the guest? Is this an expected behaviour? Should I use a host-only network for having full transfer speeds?

#14032 obsolete Base pointer isn't updated during function calling after enabling interrupts osdev
Description

During booting my operating system after interrupts had been enabled the base pointer wasn't updated during function calling. As a result the function returned to a wrong place. I'm ready to reproduce the fault with a debug version of VirtualBox made for this problem and collect any required information.
