I am pretty new to vagrant. I have installed an ubuntu 14.04 trusty box on my vagrant and will use it for my web development environment. I want to know which is the best way to disable/close/shutdown a vagrant box so that data in it remain safe in the next session? I mean when I want to shutdown my laptop (in windows 10, my host machine os is win10) there is a message telling me that virtualbox interface is open. so if I close the process then I cant access vagrant box anymore. I want a good way to close vagrant and run it in my next working session.
I read about vagrant halt before host shutdown and using vagrant up in next session but it takes too long to run a vagrant up.
**summary : I WANT A WAY TO DO THIS:
1- close a vagrant box without a data loss in it;
2- shutdown my laptop without seeing the message that tells virtualbox interface is open.
3- run vagrant box and access it with putty as fast as possible when I start working again.
is there a way to do this?**
thanks.

I would not necessarily to recommend vagrant halt which will completely stop your VM and will need to start up after you restart your host.
You can run vagrant suspend which will hold your data and you will retrieve your instance in the same state as it was before on your next startup
You can read more about the differences between halt and suspend

I am kind of new to using vagrant with oracle's virtual box. I was wondering if anyone knows if it is a good idea or not to use vagrant halt before restarting or rebooting my host machine?
Vagrant halt
is another way of saying shutdown; it is a good practice to do that since it will attempt to shut the VM gracefully where as windows will force it to. As a result you may sometimes get an error saying the VM wasn't shut properly and is now on a protected mode or saved mode and need to be rebuilt.
I'm new to vagrant, I'm using scotchbox.
I've configured a couple of vhosts in apache.
I guess the right way to do this would have been to change the provisionning of my box (as it's the aim of vaghrant right?) but i did the old school way by simpply editing my config files and so on...
Now my question is :
if i run vagrant destroy, do i loose all my configs?
is there any other command (vagrant halt, vagrant suspend?) that would allow me to reboot my host machine without loosing my config?
vagrant destroy will remove entire VM so any changes that were made manually will be lost. Vagrant halt only turns of the power so to speak so nothing is lost. If you run your machine again or reboot it all your data is save, just don't use --provision option that will recreate all initial configuration.
I'm problem with my Vagrant boxes. I had a number of boxes in operation, opened my Vagrantfile to add a new box config. Then when I ran vagrant up new_box, I was told that it could not boot and was subsequently placed in poweroff state. Now ALL my boxes are in poweroff state when I check vagrant status. The apps running on these boxes are still running though, but I can't ssh into them. I also cannot run vagrant halt, nothing seems to happen. When I run vagrant up port collisions occur.
In short, my Vagrant boxes are running (sort of), but they aren't really?
EDIT
I have tried destroying a box (rather than just halting) and then running vagrant up again, but the port is still occupied when I try to bring the box back up again... However, when I check netstat the host ports are not listed as in use by any application.
The problem was caused by an update of VirtualBox performed by the server admin (without me knowing). Also, a kernel update was being performed.
Imaging I am running a Virtual Machine guest (VM) managed by Vagrant and hosted by VirtualBox on Windows. What happens if the HOST is abruptly powered off? Is whatever data that has been added/updated to the VM lost? If this is the case, must I run vagrant halt to insure nothing is lost? Perhaps vagrant suspend would be sufficient?
Thank you for any insights or recommendations.
If the host crashes, the VirtualBox VMs will end to aborted state, but in many cases vagrant up should be enough to get them running again.
If you're unlucky and the VM got corrupted it might be that only destroying and creating it again helps. But that's why you make all modifications via provisioners, don't you? =)
vagrant halt or vagrant suspend won't do nothing in this case, as the VM is not running.
And if the host is just shut down normally, the running VMs should be suspended by recent VirtualBox versions.
If the host suffers from a power loss, the same happens to all the running guests as if they were suddenly powered off.
Data loss can happen, but it depends on the file system mount options, results can vary.
For Linux VMs using ext4 as its main file system, I'd recommend using data=journal instead of the default data=ordered and turn write barriers on by using barrier=1. The above can be done in /etc/fstab. This will help to minimize the possibility of data loss but it is NOT 100% guaranteed.
HTH
I'm using Vagrant on Virtual Box. The install scripts automatically set up PuTTY for ssh session with the environment. The thing is, it often is slow and lags. The session will freeze while I type and I have to wait about a minute for the text to appear. I was wondering if anyone else had this issue and what they did to resolve it. Thanks !
