emergency mode about nixos-config

[indiv0]

I get dropped into emergency mode when I have the filesystem sharing enabled (not sure why yet) so maybe try turning that off for now.

Also, double check that the interface being configured (in machines/*.nix) is the same as the one in the VM (check with ifconfig).

Other folks have ran into this by not carefully setting up the VM settings as I show in my youtube video. I personally can't see this happening on my local systems (recently I rebootsrapped), so I'm going to close. If anyone figures it out please let me know and I'd be happy to incorporate any changes.

i encoutered this problem when only giving the machine 4Gig of memory as some tests failed on installing, so probably make sure to give the vm enough memory.

@obi12341 do you recall what amount of memory worked for you?

I'm currently allocating 12GB and also end up in emergency mode.

Thanks!

It was resolved for me by removing the configuration for sharing the FS.

Which is OK for me since I don't need them shared.
