No. Frankly, I've avoided upgrading to precise as long as I could as I detest the new desktop (along with the huge majority of real old timer computer devs/users). Now that there's Mate, I'm moving a few machines over to get the new kernel etc. This is a new-build machine, so I had to use 12.04/64 to get past the UEFI issues. I'd just as soon be using 32 bit, sigh, but had to go with the UEFI flow, you know. I tried the advice above - using sudo apt-get install virtualbox-dkms/precise- proposed Which removed VB 4.2 and put in 4.1.something. I don't care about that one - I am not "stressing" VB much here - just using it to run windows to run some lab tools that aren't compatible with linux (for my mass spectrometer and suchlike, which barely run on windows, no hope in wine, and some of my uP dev ide's for things like PIC uPs I write code for.) . Trying virtualbox from a terminal gives me an error - "Error opening file for reading: permission denied (when run as me). It doesn't get this error running as sudo but... It still crashes during *any* VM bootup - all the way back to my bios. (Glad I have an SSD, I've never ever had to reboot linux at all, much less 6 times an hour). Doesn't matter about what VM I try to boot - Xp or Win7, several versions, & re-import the "appliance" on every try (they get internally corrupted on the attempt that fails). I did add the extension pack suitable for this version of VB since those images do use USB. Since the thing won't boot an image at all - kills the entire machine partway through, I've not been able to install/update the guest additions on these images...This is a real show stopper here - I'd hate to kick off linux and have to build a windows-only box, but my physics lab has to run...(www.coultersmithing.com/forums) Precise is not making me at all happy. VB does work on machines I "upgraded" that had it already, but not on this new build. The thing is, a fusor sometimes fries a nearby data aq PC - so I need to keep making more machines now and again...(something about a 100kv power supply arcing and making gigawatt emp - despite shielding, sometimes fries a mobo). This machine is intended to be ready for when the one in service has that happen to it. I can't get 10.04 to install at all on a UEFI mobo, even trying my best to turn the UEFI junk off in the bios (ASUS P8H 77-M/i5/8gig ram). Is there anything else I can use that will import .ova files? I'm not wed to VB or especially anything oracle...just need something that'll get my job done. On Mon, Apr 8, 2013 at 5:49 PM, Andre
