## Other
I intentionally avoided naming this plugin as 'vagrant-snapshot', because I believe Vagrant author  
implement snap shot management feature and want to use 'snapshot' as command name.

## VM configuration
In my experience, to avoid `VERR_SSM_LOAD_CONFIG_MISMATCH` error when restoreing snaphot,  
disable `USB controller` and `absolte pointing device`.
