1 Timed out while waiting for the machine to boot. This means that 2 Vagrant was unable to communicate with the guest machine within 3 the configured ("config.vm.boot_timeout" value) time period. 4 5 If you look above, you should be able to see the error(s) that 6 Vagrant had when attempting to connect to the machine. These errors 7 are usually good hints as to what may be wrong. 8 9 If you're using a custom box, make sure that networking is properly 10 working and you're able to connect to the machine. It is a common 11 problem that networking isn't setup properly in these boxes. 12 Verify that authentication configurations are also setup properly, 13 as well. 14 15 If the box appears to be booting properly, you may want to increase 16 the timeout ("config.vm.boot_timeout") value. 问题2，
