Oracle is making a new driver for VirtualBox that will allow it to do a passthrough to utilize the host’s TPM. This may be in preparation for the new TPM requirement for Windows 11 on VMs.
With the latest Windows 11 Beta Channel build 22000.194, Microsoft added Trusted Platform Module (TPM) 2.0 requirement for Virtual Machines (VMs) too, which means a Windows 11 build running via virtualization won’t receive further updates if the player doesn’t satisfy the newly added requirement.
