Virtualbox, oui mais sans (prise de) tête !
It may be interesting to have a Linux machine within range of SSH that is always available and that is windowless, i.e. running in headless mode .
For example, under MacOS, you can have Linux tools without being cluttered with a window associated with this Linux.
The advantage is to run a VM in the background without using a lot of memory.
There are two distinct parts to master:
start and stop the VM in command line mode;
allow connection by SSH from the host to this VM. To know the name of the VM:
VBoxManage list vms
To launch the vm, here called myvm:
VBoxHeadless --startvm "myvm"
Then, we can do Port Forwarding to reach the VM from the host:
VBoxManage controlvm myvm natpf1 vers_ssh,tcp,,2224,,22
Finally, if you want to properly shut down the VM:
VBoxManage controlvm "myvm" acpipowerbutton
If we want to ensure access to the VM is possible:
VBoxManage showvminfo "myvm"
NIC 1 Rule(0): name = vers_ssh, protocol = tcp, host ip = , host port = 2224, guest ip = , guest port = 22
To connect via SSH:
ssh -p 2224 localhost
