PS/2 keyboard works, but ...

And it's not letting me switch to alternative terminals. Eg: ctrl-alt-F2. Nor is there an option for selecting boot mode. [edit] Shortcut worked. Currently running dpkg reconfigure. Fingers crossed. -- Drew Edited by drook May 24, 2020, 01:22:16 PM EDT PS/2 keyboard works, but ... I can't find an old (not-USB) mouse, so I'm looking for keyboard shortcuts.

You can do anything for a short while with absolutely no harm to anything else possible. You're not an admin of a system because you want to be, you are because you have to be. You're trying to achieve a goal of an application. The system is just baggage. Go virtual and all that time will be returned to you. or at least new time won't be stolen.

So I can give you some general direction and manage expectations, but Peter or someone else would have to give you specifics. I just know I was doing it for the preceding 10 years with ever increasing expectations that s*** worked and worked well. It was touch and go in the beginning and then it matured about 5 years and then it was a matter of just choosing the cheapest implementation. And there were always free options for home users.

Some packages enable you to roll up a current hard disk and then roll it out into their environment. The problem with that is they will be forced to provide the outside shell for all the true physical device drivers of that environment. If instead you install Linux from scratch, windows from scratch, whatever OS from scratch into the default instance environment you will be assured of perfect device driver activity. Also it will be much faster because they can take shortcuts and just put in stubs for stuff they know they won't need to do.

I've not done it for Linux, but imagine that it's probably simpler. If you google up "p2v" you will find a smorgasbord of information about the topic. For the avoidance of doubt, I'm talking about the Physical to Virtual transition, where your separate standalone running computer is transferred to a virtual machine image. There are tools to do this. Edited by pwhysall May 25, 2020, 12:36:08 PM EDT Expand All History

E.g. https://www.virtualbox.org/wiki/Migrate_Windows I would dearly love there to be a way to migrate A2D/Digital IO/RS485 comms ("DAQ") PCI interface cards to a VM. We've got a bunch of custom machine control software written in Delphi 7 that is almost impossible to upgrade because later versions of Delphi use Unicode strings which break the comms, the in-house author hasn't figured out to get around that, etc., etc. It runs Ok on Win 7 and should run on Win 10, but it's always a pain to get things reinstalled on moving to new hardware when a machine dies... (sigh) Cheers, Scott.

Current kernels are "paravirtual" ready. Older ones may not be and need virtual hardware drivers just like Windows. If yours is already paravirtualized, I think you'll be able to run it as a guest OS without making changes (although for safety, image the partitions an work off the copies.) For 1): the update schedule is that of the distribution chosen as the hypervisor. I've run the open version of the Xen hypervisor for a number of years. There is no immediate need to keep the hypervisor and guest OS in step. Kernel updates to the hypervisor would require a hardware reboot.

I tried to finish the install and it said I needed to restart to complete the upgrade. When I rebooted it won't come up. If I can find a thumb drive with enough space I'll try a current install and just overwrite the whole thing. I backed up /home to an external USB hard drive before I started the whole process. Wait, duh, external USB hard drive. Going to see if I can make a bootable image on that. -- Drew
