Hello
I have exactly the same problem.
I'm running an ESXi 4.1 with my ATI Radeon 5450 (1GB Pcie card) VMDirectPath enabled.
When the VM that has this card attached and also configured with 4GB of RAM it will fail to power on.
this is from vmware.log
[msg.pciPassthru.mmioOutsidePCIHole] PCIPassthru 003:00.0: Guest tried to map 32 device pages (with base address of 0xb5d20) to a range occupied by main memory. This is outside of the PCI Hole. Add pciHole.start = "2909" to the configuration file and then power on the VM.
When I add this parameter it will fail again and suggest another value. When I put that value it will fail again and suggest the value 2888
WIth this value it will power on eventually but it will imediately crash to a BSOD. You can see the screenshot attached.
I have tried to modify BIOS settings and change cache options but nothing works!
The only way to make it work is to reduce the memory to 2GB.
I always check to have equal configured RAM with the reserved RAM.
I have tested this with Win XP 32bit, Win7 32bit and Win7 64 bit. The problem is always the same.
I even have tried this with another card an ATI 4890 graphics card and again I had the same problem!
Any ideas?
