Shutting down all VirtualBox (vagrant) VMs in one easy to use bash command (that can be put into a bash file)

I use vagrant for development. I forget to shut down a few of the VMs. When I go to log out of my host machine, the Ubuntu shutdown process appears to hang.

Might there be a way to script a close of all vagrant boxes with a bit of commandline-fu? Something like the following, but something that, well, works.

for f in $HOME/vagrant;

do;

  cd $f

  vagrant halt

done;

For a scriptable control of Virtual Box machines we can make use of the VBoxManage commands:

List running machines (returns name and UUID):
```
VBoxManage list runningvms
```

Stop running VMs by "hibernating" them (reommended to avoid data loss)
```
VBoxManage controlvm <name|uuid> savestate
```

Poweroff running VMs (not recommended because we may lose data in the guest)
```
VBoxManage controlvm <name|uuid> poweroff
```

Use ACPI in an ACPI-aware guest OS (preferable to poweroff for graceful shutdown of guests)
```
VBoxManage controlvm <name|uuid> acpipowerbutton
```

Update from OP

Based on this selected correct answer below, I've added this bash script "$HOME/bin/stop-vagrant.sh". So now I have something that can safely begin a stop of all vagrant VMs that I might have turned on yet forgotten about in a session.

vboxmanage list runningvms | sed -r 's/.*{(.*)}/1/' | xargs -L1 -I {} VBoxManage controlvm {} savestate

Command Explained:

vboxmanage list runningvms | -- gets a list of all running vms under VirtualBox

sed -r 's/.*{(.*)}/1/' | -- strips the string down to id number

xargs -L1 -I {} VBoxManage controlvm {} savestate -- runs the save state command on each box that's open.

On xargs

-L1 - take one line at a time

-I {} - uses {} as a place holder for the next command
