Disabled AMD SVM crashes host -> fixed in 1.4.2/SVN

[G. Mueller]

When starting a virtualmachine, even a new one (just created) I get a bluescreen. System is Windows XP Prof (32bit) on AMD 64 X2 Dual, Core Processor 4600+, 1,87 GB RAM ATI Radeon 1150 on Board

Bluescreen show only:

BugCheck 1000008E, {c0000005, 88b6303b, af35acd4, 0}

WinDbg gives following information:

0: kd> !analyze -v *

• Bugcheck Analysis *

*

KERNEL_MODE_EXCEPTION_NOT_HANDLED_M (1000008e) This is a very common bugcheck. Usually the exception address pinpoints the driver/function that caused the problem. Always note this address as well as the link date of the driver/image that contains this address. Some common problems are exception code 0x80000003. This means a hard coded breakpoint or assertion was hit, but this system was booted /NODEBUG. This is not supposed to happen as developers should never have hardcoded breakpoints in retail code, but ... If this happens, make sure a debugger gets connected, and the system is booted /DEBUG. This will let us see why this breakpoint is happening. Arguments: Arg1: c0000005, The exception code that was not handled Arg2: 88b6303b, The address that the exception occurred at Arg3: af35acd4, Trap Frame Arg4: 00000000

I forgot to say:

In case I get no bluescreen, virtual machine works properly. I can get a bluescreen on a fresh booted windows. Maybe I can start a virtual machine many times without bluescreen. Maybe virual machine crashes at first attempt to start. Crash occurs when changing resolution after first splashscreen with innotek logo.

I've just fixed this problem. If you wish to try a new build, then let me know. Thanks for reporting it.

Where can I get a new build? I want to try out.

You can go to the BIOS and turn on hardware virtualization (AMD-V or SVM). That should work as a temporary workaround.

Sorry, don't know where to tune! Hardware is HP Compaq dc5750 MT, ATI-BIOS-Version is 008.050.065.000, ATI Radeon Xpress 1150 Series, driver version 8.261.4-060722a-035058C-HP.

Reboot your system and go to the BIOS settings. Then there must be some CPU page with a setting for virtualization. I can give you a new version, but it's easier if you just use the workaround.

Thanks, it's working now, I have found the "dip-switch". It was hard to find under menu item "Security->OS Security->Virtualization Technology Enable"! HELP: No Help available for this feature:-(HP-Bios is always strange.)

Did anybody know when the new Version 1.4.2/SVN will be launched?

[Michael Thayer]

Unless anything unexpected happens, version 1.5.0 will be released in a week or two.
