Hello everyone. Im having issues with running VM.
VM started freezing and crashing out of nowhere, i decided to do win reinstall. After reinstall, i cannot load any VMs.
I tried looking into logs myself, but nothing much i could see. Im thinking that some part of my hardware is being corrupted.
Attaching the log, weird thing that is says no AMD-V found, although i have virtualization enabled in BIOS.

Could not attach log file, because size is 294kb

notepad . pw/ta2i4xu2

Zipped logs almost always fit.

Please right-click the VM in the main Virtualbox window's VM list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled and needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don't find that text, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

Search for "HMR3Init: Attempting fall back to NEM (Hyper-V is active)" (Too young to post links :D)

This one helped me. The VM finally started.
