Hello,
I want to restore my saved VM in order to resume work, it seems to retore completely, but the VM comes up "frozen" and does not react on mouse clicks or keyboard key strokes in any open terminal shell and thus just seems paralyzed.
(There is also some information in the terminal shells that I wish to backup.)
I have also noticed that my Caps Lock key starts flashing as soon as I activate the VB window.
Oracle VirtualBox Version 5.2.0 r118431 (Qt5.6.2).
Rebooting my PC (Windows 7) does not help -> the behavior remains the same.
Maybe someone has an idea ?
BR

Re: Virtual Machine frozen
You had a kernel panic on the guest. See https://askubuntu.com/questions/265996/ ... em-freezes and https://unix.stackexchange.com/question ... -is-frozenNPS wrote:I have also noticed that my Caps Lock key starts flashing as soon as I activate the VB window.

Re: Virtual Machine frozen
Thank you.
Is there any remedy to a kernel panic ?
I wish to not lose things I had in the terminal windows.
Maybe there is something which will do the trick ?

Re: Virtual Machine frozen
Treat it like you would treat a physical computer. Just because an OS/program that runs in the context of VirtualBox has a problem, it doesn't make it a VirtualBox problem. You're having an issue that has most probably nothing to do with VirtualBox, so my suggestion would be to treat it as such, as a native problem with the OS or the application of the guest.NPS wrote:Is there any remedy to a kernel panic ?
What has changed on your host that causes this? And please do not reply "nothing". Nothing is not a valid answer, unless your computer was shutdown completely...

Re: Virtual Machine frozen
Indeed I had to restart my computer, because our IT department wanted to install some SW Updates on it. I doubt this could have caused a kernel panic after the restart of my computer, but I don't know why the kernel is panicking, so maybe yes, this could be the reason... So I will treat it as a physical computer then and shutdown the VM - there is no means to analyze or recover ?

Same here, but most probably the updates. Hard to pinpoint.NPS wrote:but I don't know why the kernel is panicking
No, it's not easy to recover, but you've learned a lesson. 1) Backup, 2) Completely shut-down the VM if you're going to do changes to the host. Even small innocuous ones...
As for how to recover from the Linux kernel panic? I'd start by again treating is as a physical computer and search for "Linux recover from kernel panic".
PS. I've deleted your duplicate from the "Allgemeine Diskussionen" section. According to the forum rules, duplicate posts are not allowed.

Re: Virtual Machine frozen
I have checked the VM logs, but there is no further evidence.
Basically I see only the VM state changes as far as the sanity of the VM is concerned.
Thank you for help and advice so far.
I created that "duplicate" in order to extend the audience thinking that some users might never look elsewhere than in "Allgemeine Diskussionen" section, because they do not speak well English.
