Virtualbox won't start

Post by BCosell »

I recently upgraded to VirtualBox-6.1.28-147628-Win. And this evening I installed a new guest applicatsions download [don't know the version], but I haven't actually "installed" it in my vbox because when I went to fire up vbox I got:

Failed to open a session for the virtual machine Win 10.

Call to NEMR0InitVMPart2 failed: VERR_NEM_INIT_FAILED (VERR_NEM_VM_CREATE_FAILED).

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I have no idea what that means, nor what I should do to deal with it.

Assuming you have a Windows 10 host, Go back to 6.1.26. or disable Hyper-V on the host OS. VERR_NEM_VM_CREATE_FAILED: What do I do?

.28 has a bug on 10 hosts running active Hyper-V.

I went back to 6.2,26, and I downgraded the extension pack and now it is working fine. Thanks for the help
