vmx86.sys causes Win7 BSOD

[Azure0]

I use VMware® Workstation 7.0.1 build-227600.

Once, when I start the application, windows died...

Not always been so, just at times.

This is the analysis that windbg made, if you need it, I can send you the dmp file.

This verification step is only performed when Driver Verifier's checks are active. (Or on a checked build, but your dump says "Free" so that's not happening here). VMware's driver (vmx86.sys) is incompatible with these checks. You will need to either disable Driver Verifier or specifically exclude VMware's driver from Driver Verifier.

(More detail: the MDL verification check here requires a unique MDL for each page of memory we pin. MDLs are fine to use for this purpose for I/O when very little memory is actually pinned for I/O. But MDLs don't scale very well when pinning 70% of host memory, as Windows doesn't have enough kernel memory for enough MDLs to track that much memory. So we use a more efficient data structure than Windows' linked list - which is perfectly correct but which causes Driver Verifier to freak out. If we used MDLs, we could keep Driver Verifier happy but you could only pin ~10% of host memory, and 10% is too little to run a VM with any expectations of performance.)

Thanks a lot.

Now I know why it crashed:)
