Host PC (Windows 7 32Bit) reboots if you install a 64Bit Windows 7 when the host PC uses PAE

[Andre.Ziegler]

If I run VB (I tried 4.0.12 and 4.1.2) on a 32Bit Windows 7 with a PAE Patched Kernel [1] to use more memory and try to install a 64Bit Windows 7 as guest, the host PC suddenly reboots after the "Loading Windows files" finished at start of the Windows 7 setup. VMWare Player has no issues to run a 64Bit guest on a 32Bit PAE enabled host.

If I run the normal kernel everything is fine.

I attach 2 logs, 1 where it works and the other where the host simply reboots.

Any news? Is there a new test version available?

[Frank Mehnert]

Should be finally fixed with VBox 4.1.4, please confirm.

[Andre.Ziegler]

No, it is not fixed. I still have the issue.

[Frank Mehnert]

Thanks for the additional information.

[Andre.Ziegler]

Have you found a way to workaround this issue?

[Andre.Ziegler]

I get still get the error with 4.1.6.

[Andre.Ziegler]

Also doesn't work in 4.1.7.r75040.

Are you still interested in fixing this or not? If not, I can delete the 32Bit Windows.

[Frank Mehnert]

Yes, we are interested in fixing this bug but we cannot reproduce this problem, therefore not that high priority.

[Andre.Ziegler]

ok. I'm using a AMD Phenom II X945 3GHz, maybe this helps.

Hi, I also get the problem with an Intel Core i7-2600 - 3.4GHz, 4GB RAM, no PAE. guest: windows 2008 server R2, 64bits. host: windows 7, 32 bits. Virtualbox release number: 4.1.8 r75467 I note that the more I allocate memory to the guest, the more it waits before rebooting the host. So I guess there is a problem at the limit, when the memory reaches full utilization. Unfortunately I am memory-limited and it is impossible to allocate enough memory to completely avoid reboots, as in this case virtualbox cannot lock it (since it is required by the host windows). Hope this helps, Sébastien.

The bug still happens with 4.2.12. Dell E6420, Intel CPU (i5-2520), win7 professional

Most likely a duplicate of #11979. I know, this ticket is older but the other ticket contains more information. And we think we finally fixed the problem, see the other ticket.
