Just updated to Version 6.1.28 r147628 (Qt5.6.2). First thing after updating and rebooting I attempted to start my Linux Mint VM and I got the error; Virtual Box error ? Failed to open a session for the Virtual Machine Linux Mint. The details shown in the error were:
Failed to open a session for the virtual machine Linux Mint.
Call to NEMR0InitVMPart2 failed: VERR_NEM_INIT_FAILED (VERR_NEM_VM_CREATE_FAILED).
Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
I then attempted to open another VM Zorin OS16 Pro - same error.
Until this can be remedied, I'd like to find out if there is a method whereby I can rollback this latest update?

Go back to 6.1.26.
.28 introduced a bug in Windows 10 hosts while trying to get ready for Windows 11 hosts.

Had same issue with 6.1.28 update from 6.1.26
Using Windows 10 Home Version 19043
Ubuntu 20.04 LTS machine
Went to 'Turn Windows Features On or Off
Cleared check for 'Virtual Machine Platform'
So far so good, VirtualBox opens normally, and nothing seems to be broken. Guest Additions installed normally.

Yes, With Hyper-V disabled there should be no problem. .28's bug is related to running Virtualbox under active Hyper-V in Windows 10.Pagafantas wrote:'Turn Windows Features On or Off

Re: Update to Version 6.1.28 r147628 (Qt5.6.2) problem
Well, I did turn off the Windows feature "Virtual Machine Platform" and "Windows Hypervisor Platform." I rebooted afterwards and tried to open each VM and had the same failure. Scottgus you had mentioned initially to go back to the previous version. I haven't found a method to do that and would appreciate if you could point me to something that tells how that is done? Otherwise I will just uninstall VirtualBox and re-install the last version if that is available still.
Thanks
Thanks

That's the method. See https://www.virtualbox.org/wiki/Download_Old_Builds to find the earlier version. Don't forget to synchronise the Extension Pack too.Hambone_Dad wrote:just uninstall VirtualBox and re-install the last version
