VBoxTray.exe high CPU usage in RDP session

[nalmir]

Hi

version: 3.2.6 host: Windows Vista 32-bit guest: Windows 2003 Server 32-bit (guest additions installed)

When connecting guest OS through Windows RDP (I mean not VirtualBox RDP) VBoxTray.exe loads CPU up to 100%. After killing the VBoxTray.exe process it's OK.

Regards, Almir

the same issue with guest Windows 2003 Server 64-bit

The issue is actual only when single processor in guest is used.

Please reopen if still relevant with VBox 4.0.4.

still happening on 4.0.8r71778.

Host: Intel i7 CPU, Windows 7 Professional 64-bit

Guest: Windows XP Professional 32-bit, Single processor

stormjumper, you should attach VBox.log of the session where you see the high CPU usage.

Replying to sunlover:

Thanks for the pointer. Vbox.log attached, both for bridged and nat.

VBox 5.0.10 Windows 7 32 VM

EDIT: I'm sorry. Now I see that this ticket is slightly different from my problem. The ticket describes connecting via RDP to GUEST OS. I'm connecting to HOST. Should I create a new ticket?

I'm having this same problem with 5.0.10 r104061. I'm asking to reopen this issue.

My host Machine is a Windows 2002 Server 32 bits with Virtualbox 5.0.10 installed, and a Guest Windows 7 VM (32 bits) is configured.

This Windows 7 VM is not much fast. But somehow got slowly until appear frozen. From my machine (Windows 7 64bits in Lan with Windows 2002) I access Windows 2002 Server via RDP and use VirtualBox GUI to access the guest and run taskmgr. taskmgr from guest show VBoxTray.exe using CPU from 80 to 100%. This then make VirtualBox go from 15~20% CPU usage (what I think is normal) to 70~85% in the Host (Windows 2002). If I "end task" then it turns again to normal.

I'm providing VBox log hoping that it will help.

I've updated Windows RDP client on Host (windows 2003) to suport RDP protocol version 6.1. Also updated VBox to 5.0.12.

I'm no sure yet, but this seems to solve my problem.

In other words, you updated both, VirtualBox and the RDP client so we still don't know which change fixed your problem :-)

But I guess we should close this ticket if nobody else has the same problem.
