VM crashes on built VirtualBox, but works on downloaded exe

[swguy]

Find attached file (compressed); this is the output of kmk build.

[swguy]

Any ideas...???

I just noticed in GCCConfig.kmk; its using x86_64 for libgcc & also includes. Can this be a prob?

Also noticed one thing...If I launch locally built virtual box; "virtual box" shows up in the Activity Manager once we launch VirtualBox.app. But if am running prebuilt binary, "virtual box" does not show up in Activity Manager. Other 2 processes are shown for both cases (2 processes - VBoxSVC & VBoxXCOMIPCD)

[swguy]

made change in config so instead of
VBOX_GCC_LIBGCC ?= /usr/llvm-gcc-4.2/bin/../lib/gcc/i686-apple-darwin11/4.2.1/x86_64/libgcc.a
it will take regular version file...i.e.
VBOX_GCC_LIBGCC ?= /usr/llvm-gcc-4.2/bin/../lib/gcc/i686-apple-darwin11/4.2.1/libgcc.a

Unfortunately its still not working...!!

[swguy]

Okay...so it seems loading VMMR0.r0 module is failing and thats the root cause for VM crash.

On successful launch (thru pre-built binaries), we see following line in the VBox.Log; but it does not appear when we get VM crash. So essentially, loading VMMR0.r0 is failing. ANY IDEAS????

00:00:01.370221 SUP: Loaded VMMR0.r0 (/Applications/VirtualBox.app/Contents/MacOS/VMMR0.r0) at 0x13ed020 - ModuleInit at 0000000001405850 and ModuleTerm at 0000000001405810

[swguy]

So basically PDMR3LdrLoadVMMR0U is failing; this internally calls pdmR3LoadROU() which loads a module into the ring-0 context.

Am stuck here....any ideas are welcome!

[swguy]

Analyzing crash dump gives me following detail for the crashing thread; but can't fig out problem here.

[swguy]

Is this "optimization" shown below from core dump creating problem? If yes, how can I disable it??

[swguy]

Any ideas...????

[swguy]

How do you create log (or debug VM)?

Tried http://www.virtualbox.org/manual/ch12.html#idp18591280 but I don't see 'Debug' menu option as doc says.

Also, tried setting VBOX_LOG along with dest dir as in https://www.virtualbox.org/wiki/VBoxLogging; but its not creating any log.

What am I missing here? am just trying to look into the crash mentioned in the thread...

[swguy]

Got more info... But still no clue on what can be failing/changed.
