If due to any reason like slow ISP, network issues, if create lab
vagrant up --provision
got failed, then just re-run thevagrant up --provision
command to create lab. -
Once you done with usage of PORP LAB, you can just simply run
vagrant halt
command to power off the nodes and Next time when you need again PORP LAB then just runvagrant up --provision
to start all lab nodes. -
