cent2, 3 timeout 발생

텍스트로 올립니다!! 배울생각에 기대에 부풀어 있었는데 처음부터 쉽지 않네요 ㅠㅠ sulum@LAPTOP-FQRKEPUV MINGW64 /c/shell test/VWS_vagrant_script (master) $ vagrant up Bringing machine 'cent1' up with 'virtualbox' provider... Bringing machine 'cent2' up with 'virtualbox' provider... Bringing machine 'cent3' up with 'virtualbox' provider... ==> cent1: Checking if box 'rockylinux/8' version '5.0.0' is up to date... ==> cent1: Resuming suspended VM... ==> cent1: Booting VM... ==> cent1: Waiting for machine to boot. This may take a few minutes... cent1: SSH address: 127.0.0.1:2222 cent1: SSH username: vagrant cent1: SSH auth method: private key Timed out while waiting for the machine to boot. This means that Vagrant was unable to communicate with the guest machine within the configured ("config.vm.boot_timeout" value) time period. If you look above, you should be able to see the error(s) that Vagrant had when attempting to connect to the machine. These errors are usually good hints as to what may be wrong. If you're using a custom box, make sure that networking is properly working and you're able to connect to the machine. It is a common problem that networking isn't setup properly in these boxes. Verify that authentication configurations are also setup properly, as well. If the box appears to be booting properly, you may want to increase the timeout ("config.vm.boot_timeout") value.

개념이 명확하지가 않은것 같습니다.
