I was messing with systemd in my Vagrant box and I think I did something wrong since the box won't boot anymore. What I need to do is to remove certain files under /etc/systemd in my Vagrant box. However since I can't boot it, I have to remove those files from the host, but I don't know how to do it.
The VM provider is virtualbox. Both the host and the guest are ubuntu 15.04.
Thanks in advance!
option 1: you can try to add vagrant ssh -c 'cmd to run' in your vagrant file, but as you said it really does not boot, I give it really low chance to success.
option 2: create a new VM and add the hard drive from the old box to the new box (add new hard drive from existing disk), boot it and you might need to mount the new hard drive then you should be able to access your data so make the change in your /etc/systemd or whatever files you need and save. once you have made all your fix, you should be able to reboot from the old vm.
I ended up just creating a new VM but I'm fairly certain that this would work: you just mount the virtual disk file (.vmdk in my case) as a hard drive and make the fix. For different formats of virtual disks you need different tools to mount them, which I'm not going to cover here.

I have tried installing latest versions of VirtualBox and Vagrant, but I keep receiving the error message below when trying to run vagrant. How can I find the problem and correct it?
No usable default provider could be found for your system.
Vagrant relies on interactions with 3rd party systems, known as
"providers", to provide Vagrant with resources to run development
environments. Examples are VirtualBox, VMware, Hyper-V.
The easiest solution to this message is to install VirtualBox, which
is available for free on all major platforms.
If you believe you already have a provider available, make sure it
is properly installed and configured. You can see more details about
why a particular provider isn't working by forcing usage with
`vagrant up --provider=PROVIDER`, which should give you a more specific
error message for that particular provider.
Be sure to install VirtualBox first, since Vagrant depends on it.

The next step is to make some tweaks to VirtualBox and Vagrant. We need to do this because, by default, both tools store data in the same drive where they were installed (tipically the C drive). The thing with virtual machines is they can take up a lot of space, so they can eat up your main drive’s storage very quickly.
First we’ll change the storage path in Virtual Box, since it’s pretty straightforward. You now should have a program called Oracle VM VirtualBox installed. Open it and then go to File > Preferences. A
new dialog will open where you can change the folder next to the option that reads Default Machine Folder. Click the dropdown and choose Other…. Here you can choose the new folder for VirtualBox to store data.
Now we’ll do the same for Vagrant.
By default the path where data related to virtual machines is
stored is C:\Users\YourUser\.vagrant.d so I recommend changing it to a different drive. This can be done with environment variables. We need to create a variable called VAGRANT_HOME and point it to our desired location.
Open the control panel and search for the word environment. From the results choose the one that says edit environment variables for your account.
On the new dialog that appears, click the New… button.
Here you will create the new variable. Enter VAGRANT_HOME as the value for the field named Variable name.
For the field named Variable value enter the path of your choice. In my case I used C:\VM\Vagrant
I want to package a box file to a location as my disk is nearly full, does anyone know how to accomplish this.
I am running the vagrant package command
If you want to save space on your disk and you do not need to delete/recreate the VM, you can simply delete the box.
Indeed when running vagrant up, vagrant clones the current box file as the VM and do not need it afterwards. even if you delete the base box, vagrant will continue working as normal. Only in case you need to delete your VM and recreate and provision as a new VM, you will need the base box again.
I just ran vagrant provision in a futile attempt at getting my customized synced_folders directive to work and now my whole guest box is wiped out.
Is this normal? I don't see any references to Vagrant docs about this behavior.
As per the doc:
Provisioners in Vagrant allow you to automatically install software, alter configurations, and more on the machine as part of the vagrant up process.
The only thing I have in my config provision shell commands are installation commands. Nothing about wiping anything out.
I do have app.vm.provision for puppet that sets fqdn, user name and box name (along with the normal module_path, manifests_path and manifests_file). Maybe this caused things to be reset?
The Answer
Is Vagrant Provision suppose to wipe out all your data?
No. Vagrant should never harm your "data" (i.e., websites, code, etc.).
...now my whole guest box is wiped out. Is this normal?
Yes. Your Vagrant environment (in other words, the guest operating system created in a virtual environment by Vagrant) is volatile, and you should be able to destroy and recreate it at will without having any impact on your working files (because those should be kept in your local, or host, file system).
Explanation
On Vagrant's website, the very first thing they tell you is this:
Create and configure lightweight, reproducible, and portable development environments.
Your development environment allows you to work. You work on your data, in your development work environment. When you are done with your "development work environment," you should be able to delete it freely without affecting your data in the least.
Further, you should be able to send a collaborating developer your Vagrantfile so that they can create the exact same development environment you used to create your data (i.e., write your program, build your website, and so forth). Then, when you provide them with your code, they can use it in an environment identical to the one that your code was created in without having to reconfigure their own setup.
For more details about how your data files (code, working files, etc.) are kept safely in your computer while making them accessible to your guest system created by Vagrant, see my answer to this question.
So what appears to have happened was that when I set up a synced folder, it wiped out everything because there was nothing on my host machine in that synced folder. Unless there is a way to recover the lost data, there should be an unmistakable WARNING in their docs that this can happen.
I setup the synced_folder to be on my whole home directory. When I created a new machine, I cloned the one project I had saved and decided to just sync my individual projects instead of my whole user directory this time. When I reloaded, the project directory was empty since it was empty on my host machine.
So I guess, make sure the directories on your host machine are already setup with the data before configuring your Vagrantfile with synced_folder information.
I have a Vagrant set up with 3 virtual machines. Each machine has its own shell script for provisioning.
Now I would like to share the exact same status of my set up with somebody else. Since the provisioning procedure takes really (!!) long for each machine, I hope there is another solution.
Ideally I would be able to save each machine as it is in one file, which the other person then could import into Virtualbox. Is there a way to do that?
If I understand you correctly you would like to make a Vagrant base box from provisioned by Vagrant VMs. This is not recommended way to go. How you can approach this is:
Create new VM manually with required OS in the VBox.
Adjust it so Vagrant can connect to it as described here and here.
Provision it using your shell scripts.
Install all the things you would find useful to have on this VM.
Use Vagrant to package it as a base box as described here.
After packaging it with Vagrant you will get a Vagrant base box file with .box extension. You can then pass this to your team mates (usb, network share, ftp etc.) and they can add it to their Vagrant installation and use it. Whenever they will do Vagrant up they will get fully provisioned VM in VBox with all the stuff you have packaged to it. Vagrant also gives you versioning capabilities. If properly configured whenever you will create new version of base box everybody who is using it will be notified and would be able to download and use new version of your box.
Hope I understood your problem correctly and this will help to solve it.
I like how through vagrant I can spin up my machine, configure it and get to coding. However when I do vagrant halt, and then do a vagrant up again, it rebuilds my machine from the base box. All the new stuff I installed, my project repository is gone.
I can see that the virtual machine still exists in virtual box and I can use it from there, but I want to use vagrant to manage it and access it while keep the persistence of the disk as I would accessing it directly from virtual box. My host is windows, my guest is precise64.
Thoughts?

Maybe you want to use vagrant suspend? (via)
