Reload Kernel without rebooting..?
I have this box that I cant reboot in anyway. Since its a remote box and I cant do anything about it... I cant change its bootloader and thus pick its kernel.
But is there a way to unload a kernel and load another kernel?
Since I really need something like that.
and I thought I read somewere that linux can do that
So, what about that?

I cant reboot. So I am screwed.
I know 90% for sure that I did read something that it can be done.
Though I have NO idea how... Maybe that he keeps the current Kernel into the RAM and then unloads it. And then the new Kernel starts and then loads that one. And then Restarts (not reboots) the system.
Not really sure what you read. If you unload the kernel you will have to stop all services and then restart them once the kernel is reloaded. So you are rebooting.
My question why you cannot reboot this box in any way? it is because the services cannot be stopped due to client usage of them? If that is the case they will lose connection when you try to reload the kernel anyway.
Or is it because you don't have the privs to reboot this box? In that case you wouldn't have the ability to reload the kernel anyway.
Since you say you cannot change the boot loader I an thinking that you do not have the privs on this box and that would be the reason why you cannot boot this box. In this case you are SOL.
Well, its since its a vertual server.
That I dont own.
I only have access to it using SSH.
So the box has to be started..
And I have been looking for a grub conf.. Wasnt there and a Lilo conf also not there.
So Id thought, "crap"
is there anythink of way to do this?
I don't know anything about virtual servers as I have to date not worked on any. I would think how every that they would work in the same matter as any other server. What Disto is this virtual server running on and what OS is installed on this virtual server?
