Hot is: Windows 7 Ultimate 64bit VirtualBox Version: 3.0.10 Windows XP Home as Guest going into Standby, then resuming the host gives a Bluescreen:

Similar problem here on a WinXP host with Ubuntu Karmic as a guest (both 32 bit) in Virtualbox 3.0.10. Can be reproduced by:

1) Starting guest machine

2) Pausing guest machine (don't know whether this is required to reproduce)

3) Hibernating host (to disk)

4) Resuming host

5) Resuming guest

6) --> Blue Screen and reboot of host

Not sure whether this problem occurred after upgrading to 3.0.8 or 3.0.10, but it wasn't there with earlier versions of VB.

Unable to reproduce here. I suspect the BIOS is not enabling VT-x properly after resume or hibernate. (which is a bug in the BIOS) Could you try to find if a newer BIOS version fixes the problem?

You can override the VT-x initialization by defining a global enviroment variable:

• set VBOX_HWVIRTEX_INIT=global

I'll add some additional code to reinit VT-x in the next version.

Could you both also tell me on which machines this occurs? (brand, model, bios revision) Thanks.

Fix will appear in the next version. The above workaround should do the trick as well.

• For now I disabled VT in the VirtualBox Settings
• Brand Name: Home build with:

Mainboard Intel DP55KG, Bios 3822 (there is a newer one, I will try this)
