creating a new Win 8.1 VM results in "Guru Meditation"

[Fransski]

Host: Win2008 server with Virtualbox 4.3.6 on it.

As suggested, log files attached

Could you test if this test build fixes your problem?

[Fransski]

I installed this version of VB on my laptop (a Win8.1) machine, then, i tried to create the Win8.1 VM from an ISO. I noticed that the drop down box for the guest OS did not countain seperate choices for the 64 bit versions anymore, so I selected "Windows 8.1"

Immediately after starting the VM, following appeared:

Failed to open a session for the virtual machine win81b.

Couldn't find the end of CPUID sub-leaves. (VERR_CPUM_TOO_MANY_CPUID_SUBLEAVES).

Result Code: E_FAIL (0x80004005) Component: Console Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

Thanks for testing. Do you also have the corresponding VBox.log file available?

[Fransski]

log files failing Win81-64 on Toshiba Win81 Host

[Fransski]

and the log file of the failing win81-64 vm on the 2008 server

[Fransski]

So, I did some more testing:

On another machine, running Windows8, I also installed the VB version 4.3.7r91569. Here, i could easily create a Win 8.1 64 bit machine. I was also able to use the vmdk storage I previously created with VmWare and attach it to a Vbox machine.

Still,on the win 2008 server (where a Win7-64bit machine is running), I still cannot run Win8.1-64 on the VBox release. Log files attached.

For now we would like to debug the VERR_CPUM_TOO_MANY_CPUID_SUBLEAVES error as we don't know how this error is triggered. We have prepared another test build. Could you install it on your Toshiba box and try to start the VM again? It will most likely still fail but the resulting VBox.log file should contain more information about the error so we would be interested in that file. Thank you!

[Frank Mehnert]

Fransski, please could you test the provided test build and attach the VBox.log file here? We would like to fix the problem you saw but as we cannot reproduce it we need your help. Thank you!

[Frank Mehnert]

Fransski, any news?

[Frank Mehnert]

Here is another test build.

[Frank Mehnert]

Fransski, I'm still waiting for your feedback. In the meantime we released 4.3.8 RC1 which can be found ​here. Thank you!

[Frank Mehnert]

Sigh, still no feedback. VBox 4.3.8 was just released.

I have the same error. Just created ticket #12734 with details. I am willing to work with you to help solve the problem.

[Frank Mehnert]

Great, thanks! I will close this ticket as duplicate then.
