Running vagrant destroy -f && vagrant up doesn't help.
The instance is "wikispeech-wiki-buster" in project "wikispeech". It's using image debian-10.0-buster.
Looking around on wikispeech-wiki-buster.wikispeech.eqiad.wmflabs, I can see that Vagrant was able to setup the appropriate /etc/exports entry for the server side of this. We have seen some amount of instability with NFS & MediaWiki-Vagrant in the past. This time I have a hunch that the problem was the client (the LXC container that MediaWiki-Vagrant is managing) trying to mount the share before the NFS server on the hosting instance was ready. I did `vagrant ssh` to enter the container followed by `sudo mount -t nfs 192.168.122.1:/srv/mediawiki-vagrant /vagrant` and the share mounted correctly. I can't guarantee that things will work correctly following a restart of the LXC container or the hosting instance, but for now it is working.
Sorry I don't have a more satisfying answer for you. Vagrant + LXC + NFS can be a bit of a pain.
