BUG: Pipes not closing ?

[Anonymous]

I’ve installed VisualDDK 1.5 with VMWare 7.1.3, Win7X64 system, XP guest.

Followed to Quickstart guide. All is OK, excepting:

1. Clicking ‘Attach To Process’, selecting ‘vm:// ‘ works ok, but if you cancel the connection prematurely, pipes keep open and you can’t use VS integration anymore (says pipe open, close WinDbg)

2. Connecting to a VMware machine and loading a driver works perfect, but when I Unload the driver for the VDDK Control, machines freezes up, and you can’t do anything again because of pipe already open.

Can you guide me to workout the problem? I can show configurations, registry settings, etc. Maybe it’s a VDDK or VirtualKD bug? Thank you very much.

Sorry in item 2) MACHINE freezes should be “Virtual Machine Freezes”.

Eventually, DevEnv.exe crashes after the pipe stuck open event.

Thanks.

Additional info:

Connecting through COM1 named pipe seems to deadlock both VS2008 and VMWare. Both are unresponsive, but they are not marked as ‘Not Responding’ by Windows so I think it’s a livelock, they are running but not progressing a bit.

Maybe this is due to VMWare 7? I see in “compatibility” only 6.5.x, not 7.x releases.

I’ll try with VirtualBox to see what happens.

Solved! My driver was raising a Bugcheck on unload!
