I have a Vbox server running Centos 6.5 32bit, and I have it set as a dev server for some web apps I'm working on.
Guest Additions was working fine until there were some updates in the CentOS system. Upon reboot, guest additions does not work. The disc shows on the desktop, and I choose auto run when it comes up, but all it does is have a window popup and disappear very clickly (within the blink of an eye), and thats it. No error messages.
When I choose "Install Guest Additions CD Image" from the VBox tool bar I get the following image:
Where might I find a solution to this problem. I will be glad to find whatever info needed in the system, but not sure where to go. I have tried a couple of possible solutions from web searches, but so far I've had no success
this resolved it. manual install

I installed Parrot Security os-4.8 twice on virtualbox on my MacBook Air (2015), and after successful installation with no errors (both times), after rebooting virtualbox, again I get the option to use it as live or install with other options that appears as if the OS is not installed.
I checked the vdi and it appears to be of 6gb in size(I think the OS is still there).
Any suggestions? Thanks in advance.(sorry for bad English)
It sounds like you did not download the Virtual Image File ( OVA File)
( Your English is great BTW )
go to - https://parrotlinux.org/download/
Next -Go to the Virtual Tab
Download This Image
Click on the OVA file after download to import into Virtual Box
IMPORTANT NOTE - the default password and super user password for this machines image is - toor

I have Fedora 11 installed on VirtualBox. By accident some files in /var directory were damaged or removed(I don't know what exactly). Now when trying to run Fedora, it goes untill choosing the user and freezes. No reaction at mouse and keyboard clicks. Does anyone have any suppositions how to run it, or at least how to retrieve files from virtual machine? I booted it to the terminal where I updated all what is possible - gnome, etc...But still no result.
It's impossible to know what happened without knowing what got removed. However, a great way to get your files out is using scp. Good examples for this can be found here.
Alternatively, if you've installed the Virtualbox Guest Additions you can use a USB drive to retrieve your files. There's a pretty good tutorial on how to get your USB drive working on VBox here.
If you want my best guess as to what's wrong, something in your /var relating to your GUI got removed, as from what I understand you can still boot to your command line. My suggestion would be to get what you need off the machine using the above tools and get a fresh install.

I have Manjaro Linux on my laptop with KDE desktop. In desktop environments you can have multiple desktops. I want to turn one of these desktops into a permanent terminal. A complete full-screen terminal like the one you get when you don't have a desktop environment installed. Is there anyway to turn one of my workspaces in KDE into a permanent terminal ??
Did you try using a plasmoid? It's not complete full screen but it's as near as it gets.
For example this or this.
Also, have you tried Yakuake? It's not located on the desktop, but invoked by a key press (usually F12) or by the mouse reaching the top border if you want. It's the first program I install on any KDE setup, it's vital to my workflow.

Installed Mint on a brand new Lenovo Z585 Ideapad alongside the pre-installed Windows 8. Everything seemed to go fine, until the reboot, which simply dumped me at a Grub prompt.
I tried the usual ls investigations, but my Mint partition (/dev/sda9) returns an error along the lines of "invalid file name ''." - sorry I can't be more precise right now.
I've booted back into the LiveCD and run boot-repair, which generated the following summary - http://paste2.org/Owy3XNpH.
os-prober recognises my Windows installs (the real install and the recovery thinger), but no Mint.
As far as I can see, browsing the partition through the live cd, the install itself is fine, but I'm more than willing to be corrected. Can anyone help?
Adding the answer in case others have this problem.
Turns out that SecureBoot was in the Security section of the Bios, and not in the Boot section, where I was looking for it.
Disabling it and running boot-repair fixed the problem.
No boot loader is installed in the MBR of /dev/sda

I'm running vagrant with an Ubuntu server 10.04 LTS box. The local folder on my Mac is mounted with NFS and all works fine except for one thing.
I'm developing a PHP project which uses Twig as template system but whenever I modify a template on my Mac and save it, it required two refreshes before Twig can load the template. The first refresh i'm getting an exception telling me that the file cannot be found. the second refresh is fine and the template loads just fine.
When switching back from NFS to the default VirtualBox filesystem all is fine but my dev site become terribly slow, almost to the point it's unworkable.
Anyone has an idea in what direction to look or has a clear solution?
