Error Starting Virtual Machine

Post by Mobile EIC »

Hello,

I've setup a virtual machine on a new laptop trying to run Windows 7 but getting the following error:

Failed to open a session for the virtual machine.

Failed to load R0 module C:\Program Files\Oracle\VirtualBox/VMMR0.r0: SUP_IOCTL_LDR_OPEN failed (VERR_LDR_GENERAL_FAILURE).
Failed to load VMMR0.r0 (VERR_LDR_GENERAL_FAILURE).


Result Code:
E_FAIL (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {872da645-4a9b-1727-bee2-5585105b9eed}


I've tried all suggestions in previous threads. Currently I have 6.1.28 and I have the Ext packs installed as well. Any help would be greatly appreciated.

Rolling back to 6.1.26 was suggested in these other threads. That did not work for you?

What host OS are you running?

I had the same issue running Windows 10 20H2 with VirtualBox 6.1.2x and a Ubuntu guest.

I had to rollback as far as 6.1.16 in order to get the issue resolved - it seems like this may be a regression of a previous fix for HyperV - I only encountered this issue once I enabled HyperV on the host machine.

Looks like this may be fixed in 6.1.30 :-)
