VBox doesnt reboot or shutdown with any Linux distros

[Arijitslg1]

Why does the VirtualBox doesnt reboot or shut down properly with any of the Linux guest OS. I tried with Ubuntu and it says something "ModemManager is shut down" and in the next line "nm-dispatcher.action: Disconnected from the system bus, exiting." then next line ""Unmounting temporary filesystems..." again next line "Deactivating swap" and finally, it says "Stopping early crypto disks...". It doesnt have anything after that. So finally I had restart the VBox as the screen was stuck there. It happened for all the reboots or shut down that I tried. The same issue occurred while I tried with Linux Mint 17.1.

For the vast majority Linux guests reboot and shutdown correctly. Apparently thre is something going on with your system.

Minimum information needed for assistance.

Right click on a VM in the VirtualBoxGUI. Select "Show Log". Save "VBox.log" to a file. Compress that file and attach it to a message here. Make sure the VM is fully shut down beforehand.
