virtualbox.org

Good morning.
I am using the latest version 6.1.32
it always worked, from today I get the same error as this thread.
I checked in the bios the virtualization activation is ok I always get the same error, I don't know how to fix.
Thank you

Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

Here is the log.
Thank you

RAM overcommitted, and anyhow there's no way an 8GB PC running Win64 can afford to dedicate 4GB to a VM. Reduce VM RAM to 2GB. Consider adding RAM to the host if you want to run VMs of this size on it.

And VT-x is disabled in the host BIOS. See FAQ: I have a 64bit host, but can't install 64bit guests.

Good morning.
I restored the OS image with version 6.1.30 and everything works fine, so I am attaching the log file.
The problem arises when I upgrade to version 6.1.32 I get the error I described above.
Even when uninstalling and reverting to the previous version (6.1.30) I always get the same error.
I don't understand where this latest version is causing problems on my operating system, but it certainly prevents it from working properly.
So I restored the OS image again with version 6.1.30 and everything works fine.
I really don't understand, I presume the latest version is not compatible with my obsolete hardware (i5 750)

When you followed the link provided by mpack, did you read and follow the last post of the FAQ precisely (disabling all mentioned Windows component and using the bcdedit command)?

The background reason is that the error message can perhaps indicate a partially active Hyper-V on the Windows host.
