virtualbox.org

Currently, i am running virtualbox on a linux host. An year ago, windows was my host system OS and i was able to run vm without any issue. But after installing virtualbox on a linux host, it shows vt-x error. Ive enable virtualization in bios. But it still gives error. What should i do ? Note: its not a dual boot system, i have only kali linux on physical drive

Please provide a VM log file. With the VM fully shut down, right click it in the GUI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.
