#6135 obsolete Mouse locking in VMWare Console when run within VirtualBox guest yardbirdsax
Description

When using VMWare VSphere console version 4 within a VirtualBox guest (WinXP SP2), the mouse will intermittently (and seemingly randomly) "lock up" and not respond to clicks. The mouse will move around but clicking either within the VMWare console screen or within the VirtualBox guest screen does not function. In addition most keyboard controls seem not to work. The only way I've found to correct it is to use Cntrl-Delete and force the VBox guest to bring up task-manager, then kill off all the vmware processes.

This is on a Linux host (Ubuntu 8.10). Log file is attached.

#15295 fixed Networking extremely slow with Intel PRO/1000 yardas
Description

I tested only NAT but it is probably similar in other modes.

Data flow of download (to guest) is mostly 40-50 kB/s no matter where the download originates from (including the VM host itself). Sometimes it peaks to MB/s but shortly it returns to 40-50 kB/s. Sometimes it is even slower.

The download speed returns to normal if GRO is disabled, i.e. the following command run in the guest fixes the problem:

# ethtool -K NIC gro off

I think if the GRO is broken in the driver it should be switched off by default. IIRC it was, but the problem started to manifest recently, so there may be an regression.

#14099 wontfix MSR_PKG_C[8-10]_RESIDENCY are not provided with Haswell-ULT host CPU yarda
Description

MSR implementation under VirtualBox is quite usable, but the following MSRs are not provided if running on Haswell-ULT host CPU (e.g. CPU model number 0x45):

MSR_PKG_C8_RESIDENCY, MSR register 0x630
MSR_PKG_C9_RESIDENCY, MSR register 0x631
MSR_PKG_C10_RESIDENCY, MSR register 0x632

This may crash applications depending on these MSRs as they should be supported according to CPU model number. Currently PowerTOP is known to crash if running in guest using Haswell-ULT host CPU.
