VirtualBox has always been the go-to piece of software to spin up virtual machines on your workstation.
More often than not, you will work with VirtualBox using its GUI. However, for those occasions where you are SSH’ing into a remote workstation running VirtualBox, it is often easier to work with it using the command line instead of forwarding X.
This post will be an ever growing list of useful VirtualBox commands.
Import a virtual machine file into VirtualBox:
vboxmanage import <FILE>
In certain scenarios, you may not want virtual machine file you are importing should to regenerate its virtual NIC MAC addresses. In that case, pass the keepallmacs flag:
vboxmanage import --options keepallmacs <FILE>
Start one virtual machine:
vboxmanage startvm <NAME>
Start many virtual machines:
for i in <VM1> <VM2> <VM3>; do vboxmanage startvm $i; done
Stop one virtual machine:
vboxmanage controlvm <NAME> poweroffip
Stop many virtual machines:
for i in <VM1> <VM2> <VM3>; do vboxmanage controlvm $i poweroff; done
vboxmanage or tools like packer, you might need to reference a list of all the supported ostypes - operating system types - when creating virtual machines.
To see a list of valid ostypes, run the following command:
vboxmanage list ostypes | grep ^ID
Create host only network interface adapter:
vboxmanage hostonlyif create
Remove host only network interface adapter:
vboxmanage hostonlyif remove vboxnet0
By default, a VirtualBox virtual machine will use an IP address you cannot route to. If you want to SSH to that virtual machine without adding another host only network interface, you will need to setup a NAT to port 22.
NAT SSH to virtual machine:
vboxmanage modifyvm "vm1" --natpf1 "guestssh,tcp,,22111,,22"
Delete NAT SSH on virtual machine:
VBoxManage modifyvm "vm1" --natpf1 delete "guestssh"
