I have been in touch with VM for a long time, and then I used virtual box on the Internet...
It's still the past, because ubuntu is charged, and VB is open source and so on.
Recently, a new computer installed VB, a relatively new version, and found that when installing Ubuntu, it always prompted a serious failure to start the virtual machine.
The failure is displayed as follows:
irtualBox的Error In supR3HardenedWinReSpawn ， Error relauching VirtualBox VM
solve needs
1. Install **up.,inf in the drv directory, right-click to install (install \drivers\vboxsup\VBoxSup.inf in the Virtualbox directory)
2. Also reset the registry, change the value of start under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VBoxSup to 2,
3. Restart the computer.
