never tried 3.0.10

Yes.
apt-get update
during the upgrade to 3.0.12

actual:    
a. no text is pasted
b. excessive CPU usage
c. excessive system temperature


5. shutdown guest usinng start / ....
6. guest shut down hangs with message box ( screenshot: clipboard.shutdown.screenshot.png )
   end program - VBoxSharedClipboardClass
   this program is not responding
   end now / cancel

VBox.log

[Michael Thayer]

If you run VirtualBox with the following environment variable set, you will get a lot more logging about what the shared clipboard is doing:

VBOX_RELEASE_LOG=shared_clipboard.e.l.l2.l3.f

I wonder though whether the clipboard problem is a symptom of something else, as VBoxSVC shouldn't have anything to do with the shared clipboard.

[sbenotreally]

OK. Here is the log. I ran these commands to get it:

VBOX_RELEASE_LOG=shared_clipboard.e.l.l2.l3.f VirtualBox

[sbenotreally]

VBox.log after VBOX_RELEASE_LOG=shared_clipboard.e.l.l2.l3.f

[Michael Thayer]

Either the additional logging didn't work for some reason or there is no shared clipboard activity whatsoever in the guest. Could you try re-installing the Guest Additions?

[sbenotreally]

Re-installed Guest Additions as follows:
1. remove Guest Additions 3.0.12
2. reboot guest
3. install Guest Additions 3.0.12
4. reboot guest

Symptoms no longer reproducible.
This problem seems fixed, unless you want to refer it to another queue for treatment as a problem during upgrade.

Thank you!

Thanks for the feedback. I will close this then. Please re-open if it reoccurs.
