VirtualBox and Virtualization based security

[ZwClose]

Hi,

Recently I turned on VBS (also known as Core isolation/Memory integrity) and noticed that VirtualBox stopped working. When trying to power on a VM I get the following error:

SUP_IOCTL_LDR_OPEN failed (VERR_LDR_GENERAL_FAILURE).
Failed to load VMMR0.r0 (VERR_LDR_GENERAL_FAILURE).
Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap

Software version:

Win10 21H1
VirtualBox 6.1.30

So I wonder if VBox is compatible with VBS?
Network driver VBoxNetAdp6.sys isn't VBS aware but I guess it's only part of the issue.

TIA

For now, Virtualbox and Memory Integrity don't get along. The devs are working on it.

6.1.26 is the last version that is working with this feature enabled, but it does not support Microsoft Windows 11 guests.
