vagrant 的同步文件配置没法生效解决办法

配置主机与虚机同步共享的文件夹

config.vm.synced_folder "./labs", "/home/vagrant/labs"

从新载入后报错

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 home_vagrant_labs /home/vagrant/labs

The error output from the command was:

mount: unknown filesystem type 'vboxsf'

解决方法

vagrant plugin install vagrant-vbguest
