Highlights
- QEMU v9.1.0 The backend has been updated to the latest upstream QEMU which brings with it a variety of bug fixes and performance improvements.
- (macOS 15) Nested virtualization for Linux Linux VMs using Apple Virtualization backend on macOS 15 and M3 or newer will now have nested virtualization enabled by default.
- (macOS 15) Total Store Ordering for QEMU VMs using QEMU backend on macOS 15 can now enable TSO (in QEMU settings). When TSO is enabled on a guest operating system that is aware of the system register (i.e. Rosetta for Linux), performance of Intel emulation within the guest can be greatly improved.
Notes
- There is a known issue amongst some users with UTM running on macOS 15 where accesses to files will fail due to permission error. We are still investigating this (#6639) and related issues. In the meantime, we do not recommend upgrading to macOS 15.
- The update to QEMU v9.1.0 will likely introduce new issues and regressions. If you experience any problem (crashes, performance, errors) that was not evident in v4.5.x, please open an issue and provide all the requested information. It would also be helpful if you can provide a reproducible example and note the last version of UTM where it worked properly.
Changes (v4.6.0)
- Updated to QEMU v9.1.0
