I don't think the two issues are directly related. Failure to attach a keyboard wouldn't have anything to do with a later failure to load a kernel.
Unfortunately as you no longer have the damaged system, there is no way to determine the cause or to initiate a repair. |

I ask coz there is no guest additions available for OpenBSD. |

Well, I ran OpenBsd for almost 2 years on a virtual box VM , before I decided to install it
on the HD , and had no issues. The guest additions is a non issue, when I needed to access files on the host system I just used/use ssh, and scp or sftp to connect to the host. Lately I am using QUEMO for my VM's it does not use any "guest additions", I don't think they are really necessary. Quote:
We get a lot of unexpected power failures here, and when that happens, sometimes I need to run 'fsck' when I boot, but it has never caused any thing that was not repairable. For what it is worth, I do not think using Ubuntu as a host is a very good idea. If I had a problem with OpenBsd not booting any more, and could not find a solution I would try re-installing OpenBsd, or have used my backup to restore the system. I have do not usually have any problem with OpenBsd detecting devices when connected , even after it was booted and running. However, I have a couple of portable USB drives that it is better to have them connected before booting, in any event , if and when it does not detect a device that gets connected while it is running, and I reboot, never have had the kind of failure you mention, and usually it detects the device when it boots.

An installation of an alternative OS indicates a clear dissatisfaction with - or distrust of - OpenBSD.
---- Regarding backups: We backup in fear. Fear of finger-fumbles, mistakes, software problems, and hardware troubles. But we restore in panic. Unless we regularly test our backups with our restore procedures, we have no guarantee that we will be able to successfully restore our systems. Regular testing, if successful, reduces the stress of restoring when we actually need to do so. |

Well, in my case, it was clearly a distrust of me, myself and my PEBKAC

Well, that's good,... Hopefully it does not occur again, but if in the future it does,
if it at least gets to the "boot> " part, you can , maybe boot as a single user (root), if you can , there is a chance you can repair the system boot process so that it will boot properly, also you can them access logs, to get info on what happened. http://www.openbsdsupport.org/ed_and_fstab.html Quote:
I have a bootable usb device I made, with OpenBsd on it, this gives me a "live USB" device that I can use to work on the system if need be, never have needed to use it though. There is some more details on making a "live" usb , or CD here: http://daemonforums.org/showthread.php?t=5234

This type of problem is possible through admin error -- I know, because I did it to myself only a week ago on this laptop I'm typing from. I'd used dd(1) as root, with a typo in the sd(4) device node name. My "ooops" destroyed the disklabel and the root partition, though still had a functioning 2-stage bootloader. The second stage bootloader was still in its sectors, it had not been overwritten. But the system was un-bootable. Did I panic? Of course. And I was angry at myself for my finger-fumble. But I test my backup and recovery procedures. I was able to restore the disklabel from backup, recreate the root partition from a recovery staging system, and restore /etc and /root from backup. End result? No data lost, just some time, and now ... some public embarrassment. |
