Windows 7 guest crash on Mac OS X 10.6.8 host - VERR_MAP_FAILED (-75)

[Gingerglaahk]

When setting video memory to over 128MB on Windows 7 guest, the VM crashes immediately after selecting start, giving the following message:

Failed to map a memory object. (VERR_MAP_FAILED).

I am using VBox 4.1.8 on Mac OS X 10.6.8 with 8GB RAM.

Attached are the log file, and two screenshots.

Still relevant with VBox 4.1.22 / 4.2.0?

This very same problem still occurs in Macosx 10.6.8 (Darwin 10.8.0) with VBox 4.3.16 (MacbookPro, 2009 edition). The relevant error lines in the vbox.log file:

00:00:01.748232 AssertLogRel /Users/vbox/tinderbox/4.3-mac-rel/src/VBox/Devices/Graphics/DevVGA.cpp(6043) int vgaR3Construct(PDMDEVINS*, int, CFGMNODE*): RT_SUCCESS_NP(rc) 00:00:01.748253 PDMDevHlpMapMMIO2IntoR0(0x80000,) -> VERR_MAP_FAILED 00:00:01.748270 PDM: Failed to construct 'vga'/0! VERR_MAP_FAILED (-75) - Failed to map a memory object.

Reducing video memory to 128M allows the machine to start up fine. This is a working Windows 7 vbox image exported from Debian Linux 7 to the Macbook as a .ova package.

Re comment 3: could you please attach complete VBox.log?
