#7516 obsolete Nvidia Graphics Driver 260.63 Breaks 3D Acceleration Will
Description

Hi,

So I am running http://www.nvidia.com/object/win7-winvista-64bit-260.63-beta-driver.html on Windows 7 x64.

If I enable 3D Acceleration for a Windows Guest OS and try to boot it up I get the wonderfully famous "VirtualBox GUI has stopped working" error screen.

#7517 obsolete W2k3 guest time sync problems (VbglR3GetHostTime failed; rc2=VERR_IO_GEN_FAILURE) virtboxguy
Description

Virtualbox 3.2.8 running on Windows Server 2003 (32Bit) Guest: Windows Server 2003 (32Bit) GuestAdditions: 3.2.8

The time of the guest isn't synchronized. Especially after a savestate and resume the guest clock is far far away from the host clock. In the Log files I found:

00:01:32.296 Guest Log: VBoxService.exe: Error: VbglR3GetHostTime failed; rc2=VERR_IO_GEN_FAILURE

I've checked this with an earlier version of VIrtualbox (3.1.8, also GuestAdditions downgrades) but observe the same error. An test on Windows 7 host didn't show this behaviour, so I suggest it's an Server 2003 host issue.

Even with "VboxService -vvv" I didn't get more information about the timesync problem.

Attached the vbox.log

The issue is rather critical, cause the clock is so fast out of time, that an workaround with a very shot poll interval of the windows w32time daemon is necessary.

#7522 obsolete CPU Hotplug / Hot-unplug is unstable Technologov
Description

Host: Windows XP, Core 2 Q6600, VBox 3.2.8.
Guest: openSUSE 11.3 64-bit (and other Linuxes)

I did:

VBoxManage modifyvm <vmname> --cpuhotplug on
VBoxManage modifyvm <vmname> --cpus 2

after VM booted...

Several time re-plugged CPU:

VBoxManage controlvm <vmname> plugcpu 1
VBoxManage controlvm <vmname> unplugcpu 1

From inside guest: (openSUSE 11.3 64-bit)

[  884.071618] ACPI: Device don't exist, dropping EJECT

Similar, but different problems were seen on many other guest OSes: RHEL6 (BETA1), Fedora12, openSUSE 11.0/11.1/11.2 (32+64bit), ...

For now, only under Fedora 13 this feature magically worked. VBox log attached.
