Nearly four years after its last major release, VirtualBox 7.0 arrives with a… host of new features. Chief among them are Windows 11 support via TPM, EFI Secure Boot support, full encryption for virtual machines, and a few Linux niceties.
The big news is support for Secure Boot and TPM 1.2 and 2.0, which makes it easier to install Windows 11 without registry hacks (the kind Oracle itself recommended for 6.1 users). It’s strange to think about people unable to satisfy Windows 11’s security requirements on their physical hardware, but doing so with a couple clicks in VirtualBox, but here we are.
VirtualBox 7.0 also allows virtual machines to run with full encryption, not just inside the guest OS—but logs, saved states, and other files connected to the VM. At the moment, this support only works through the command line, “for now,” Oracle notes in the changelog.
This is the first official VirtualBox release with a Developer Preview for ARM-based Macs. Having loaded it on an M2 MacBook Air, I can report that the VirtualBox client informs you, extensively and consistently, about the non-production nature of your client. The changelog notes that it’s an “unsupported work in progress” that is “known to have very modest performance.” A “Beta Warning” shows up in the (new and unified) message center, and in the upper-right corner, a “BETA” warning on the window frame is stacked on top of a construction-style “Dev Preview” warning sign. You’re certainly not likely to get a Windows 11 guest running through the ARM Mac’s Rosetta layer at this stage (I tried anyways, but fell far short).
Beyond that bright caution signage, Mac clients, on both Intel and ARM, have now dropped all Kernel extensions, relying entirely on Apple’s hypervisor and vmnet frameworks for their function. For the moment, though, that means they’ve lost internal networking functions; Oracle says it will be “provided at a later date.”
Linux hosts receive “reworked” screen resizing, along with “initial support” for automatic updating of the Guest Additions inside Linux guests. Perhaps most interesting for Linux hosts is support for DXVK, the Vulkan-based implementation of DirectX layers that allows for running 3D Windows applications in Wine. This provides some parity with Windows hosts, which receive standard DirectX 11 support in this 7.0 release.
Among other improvements to this version:
- Cloud machines can be managed locally
- A performance monitoring tool for guests
- Wizard tool integrates unattended guest installations
- Vorbis is the default audio format for recording with WebM containers
- Virtual IOMMU devices for Intel and AMD
- Better theme integration on Mac and Linux systems, with updated Qt/UI looks and fixes.
VirtualBox 7.0 is available for hosts on Windows, Linux, Solaris, Intel-based Macs, and, as noted, with heavily flagged early-stage support for ARM-based Macs.
