Hi All,
Running vbox (latest) on a win10pro (latest), up until last wk, I was able to start any vm (linux or windows) straight from the vm shortcut without needing to open the vbox manager. However, when I do that now, none of the VMs will boot up, they hang during loading. As soon as I open the vbox manager, the VM will resume its boot.
Any ideas?
Thanks!

This is an interesting twist! Haven't heard of this before.jacks01 wrote:As soon as I open the vbox manager, the VM will resume its boot.

Try setting the VM to 2 processors if it is not already.
If that doesn't work, right-click the guest in the main Virtualbox window's guest 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. 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.
