HAOS won't boot after unclean VM shutdown

I’m running the standard HAOS VM using VirtualBox on a Mac Mini host. Today the host crashed with a kernel panic. On restart, the HAOS VM went through a rapid repeating loop of start-up, fail to start Docker, shut-down, repeat. After a while it just stopped on an “Autoboot” prompt.

I have a VM snapshot from a week ago, but I’ve made a lot of configuration changes since then that I don’t want to lose. How can I fix this, or at least copy out my HA configs before resetting to the last VM snapshot?

You should be able to extract your configuration files from the vdi virtual disk file. Google search (or duckduckgo) is your friend.
