VT-x is not available (VERR_VMX_NO_VMX).

Post by darko_mi »

Moin

Seid einer Woche funktioniert meine VM nicht mehr (Ubuntu 18.04 64bit) virtualisiert auf Windows 10 Enteprise 10.0.16299 - 64bit System (Dell Latitude 7490).

Habe im BIOS verifiziert, Virtualiszation gesettz (Enabled Intel Virtulaization Technology) + VT for Direct I/O (Enabled VT for Direct I/O) + Trusted auch angewählt...

Fehlermeldung:
The native API dll was not found (C:\Windows\system32\WinHvPlatform.dll) (VERR_NEM_NOT_AVAILABLE).
VT-x is not available (VERR_VMX_NO_VMX).

Fehlercode: E_FAIL (0x80004005)
Komponente: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
Die dll File gibt es wirklich nicht in meinem Win/System32 Pfad.

Hat jemand ne idee?
(Bei der VM-Settings "NAME_OF_VM".vbox habe ich <HardwareVirtExLargePages enabled="true"/> probiert -> Leider ohne Erfolg, wird immer zurück gestellt...)

Jemand eine Idee?

  1. You have Hyper-V enabled, and/or something is using Hyper-V.
  2. VirtualBox tries to use the Native Execution Manager (NEM) with the help of Hyper-V. But that requires Win10 version 1809 and later, see VirtualBox 6.0 and Hyper-V.
You have two options:
  1. Update to 1809, keep on using Hyper-V, use VirtualBox in NEM mode (which is really slow).
  2. Disable all Hyper-V components:
    • Hyper-V
    • Virtual Machine Platform
    • Windows Hypervisor Platform

If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.
