VM crashes with “HV_ERROR”

### Describe the issue

QEMU just up and crashes while I am running a VM. The only diagnostic given in the UI is “error: HV_ERROR”, although a macOS Crash Reporter dialog also appears at the same time. Examination of the crash log reveals that an assertion failed in `assert_hvf_ok` and as a result we `abort()`.

**Configuration**
* UTM Version: 2.4.1 (40)
* OS Version: macOS Monterey 12.0.1 (21A559)
* Intel or Apple Silicon? Intel

Unfortunately, on Monterey the Crash Reporter will no longer produce human-readable logs using the technique you stated in the issue template. The above file (what was shown when I clicked Reveal in Finder) is a plaintext JSON file. Rename to end in `.ips` and double-click, and you will have the “translated” crash log.
