I run the packer build -only=virtualbox-iso centos.json in my windows10.
It was stopped at "==> virtualbox-iso: Waiting for SSH to become available..." command line.
I checked the log in virtualbox, it show "Failed connect 10.0.2.2:8853".
But I can ping the ip successfully in another virtualbox（created by manual）。
