--- Comment #1 from Aleksandr Fedorov <afedo...@freebsd.org> ---
The main problem is that the VM is destroyed asynchronously via sysctl:
https://github.com/freebsd/freebsd-src/blob/main/usr.sbin/bhyvectl/bhyvectl.c#L2397
https://github.com/freebsd/freebsd-src/blob/main/lib/libvmmapi/vmmapi.c#L88
https://github.com/freebsd/freebsd-src/blob/main/sys/amd64/vmm/vmm_dev.c#L1080
Therefore, bhyvectl --destroy --vm=test0 completes before the VM is actually
destroyed.
Moreover, even the /dev/vmm/test0 device is removed before the actual
destruction of the VM occurs.
And I don't know of a guaranteed way to check if a VM is destroyed from
userspace.
As workaround you can use:
bhyvectl --destroy --vm=test0
sleep [N[
bhyve -AHP -c 1 -m 1024M ...
But this is not a 100% reliable solution.
