You have two ways to do this, I’ll call it dirty way and clean way:
1. The dirty way
Create a box from your current virtual environment, using
vagrant package command:
Then copy the box to the other pc, add it using
vagrant box add and run it using
vagrant up as usual.
Keep in mind that files in your working directory (the one with the
Vagrantfile) are shared when the virtual machine boots, so you need to copy it to the other pc as well.
2. The clean way
Theoretically it should never be necessary to do export/import with Vagrant. If you have the foresight to use provisioning for configuring the virtual environment (chef, puppet, ansible), and a version control system like git for your working directory, copying an environment would be at this point simple as running:
git clone <your_repo> vagrant up
