Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem "vboxsf" is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attempted was:

mount -t vboxsf -o uid=1000,gid=1000,_netdev vagrant /vagrant

The error output from the command was:

/sbin/mount.vboxsf: mounting failed with the error: No such device


c:\var\dev\DB\rep_test_centosstr9_pg16

対処：共有フォルダ使わないことにしてしまう

以下をVagrantfileに追記

    config.vm.synced_folder ".", "/vagrant", disabled: true

VirtualBoxのバージョン、実際のデバイス配置、Guest Additionsのバージョン、その他ちゃんと確認して、
正しく対処もできると思うけど、sshできるならscpで良いや、という感じなので、横着して上記で対処。

以上
