VERR_LDR_MISMATCH_NATIVE when trying run VM in VirtualBox-5.0.5-102614-Win

[Leonardo Lira]

Host : Windows 10.0.10240 Guest: Windows XP, Ubuntu and CentOS

After install the VirtualBox-5.0.5-102614-Win test version, I deleted my old Windows XP VM, create a new and I did a boot. When VirtualBox try to start the VM, an error message is displayed: Failed to load VMMR0. r0 (VERR_LDR_MISMATCH_NATIVE)-E_FAIL (0x80004005).

Below the details of the error:

Falha ao abrir uma sessão para a máquina virtual WindowsXP.

Something weird is going on here. Do you have any anti-virus/whatever software installed?

I've made some experimental changes to try avoid this problem. Could you give the build below a try and report back whether it worked or how it failed, please?

Last night I used the 5.0.5-102660-Win test version. After uninstall the VBox and delete the folder in 'Program Files', I did the instalation ( Driver verifier off, administrator privilegies, setup, start the VirtualBox, create and boot a new VM ) and all works fine!.

Unfortunately I had two BSOD in sequence after reboot the Windows 10. I restored the system to a recovery point that I made earlier, but doing that, the VirtualBox instalation was lost.

I'll verify what happended and try a new instalation.

Hi Bird,

The 5.0.5-102706 build works fine after install and no BSOD after Windows restart.

Thanks !

Fix is part of VBox 5.0.6.
