What happened?
Using powerpoint on the guest, the VM frequently aborts.
The virtual box logs does not report anything particularly interesting: it ends abruptly while the VM is still running, which I think points to the Linux-host VirtualBoxVM process being killed or crashing externally.
The strongest suspect is the shared clipboard:
- Shared clipboard is set to Bidirectional.
- Immediately before the log ends, VBoxTray initializes Windows OLE clipboard handling.
- PowerPoint places complex OLE/HTML/metafile objects on the clipboard, a path that has caused VirtualBox crashes before.
- 3D acceleration is disabled, so this does not look like a virtual-GPU failure.
Looking at a dump on the host seems to confirm this, since it includes details such as
TID: 1064292 (SHCLX11)
Signal: 6 (ABRT)
...
libXt.so.6
XtAppPeekEvent
VBoxSharedClipboard.so
Full dump (slightly redacted for usernames, etc) is attached.
While there seem to be multiple clipboard related bugs open both on the old issue tracer and the new issue section on github, none of them seems 100% overlapping to this one.
How can we reproduce this?
Using powerpoint on the windows guest causes the WM to abort about every hour or so. This might depend on the way in which powerpoint is used, though.
