fiza Posted February 6, 2015 Posted February 6, 2015 We have been using a vbox set up following the guidance on this thread http://www.edugeek.net/forums/how-do-you-do/95325-virtualbox-image-programming-classes.html Its all been working fine but now random machines in the room refuse to start the vbox. All the machines are the same with the same image and previously have had virtualbox with a win7 image on it working fine. Any ideas?
synaesthesia Posted February 6, 2015 Posted February 6, 2015 Have you checked the relevant files are still there? Oddly enough, every now and then some of our machines seem to lose the configuration file for no apparent reason.
jinnantonnixx Posted February 6, 2015 Posted February 6, 2015 (edited) Are you running VirtualBox on Linux or Windows? If Linux, occasionally a kernel upgrade will cause the underlying VMs to be out of step. Resolved with: sudo /etc/init.d/vboxdrv setup Otherwise, do the virtual machines expect some real hardware which is missing or changed on the real machines? This sometimes happens when you create a machine on, say, Linux, and move it to a Windows machine. There are XML meta files (*.vbox) files which reside with the virtual disk images. You could try inspecting these to see if there's something strange with the configuration. Edited February 6, 2015 by jinnantonnixx

The exe I created which wrapped up the batch file with all the settings is still there in the c drive. Even directly running that doesn't do anything.

fiza Posted February 10, 2015 Author Posted February 10, 2015 Virtualization enabled in BIOS ? Nothing has changed. Working one day - stopped the next. Re-image and its all good.
