--- Comment #3 from Michael Dexter <editor@callfortesting.org> ---
Sorry I was not clear and I have tried this several more times:

For my initial smoke test of a VM with an months-old version of 15.0-CURRENT,
the VM booted, but would boot when attempting to boot it again.

Since moving to 15.0-ALPHA1, I have a more formal test regime of testing the VM
with different memory allocations and with and without host reboots.

On 15.0-ALPHA1, the VM's behave in three ways from what I can tell:

1. Fail quickly with the Assert
2. Take several minutes or seconds to Assert
3. Hang for around 12 hours with 100% load for the bhyve process at which point
I terminated it.

I have tried a different storage model but I welcome your advice on what other
parameters to change to help isolate this.

Thank you!
