KVM Disabled by BIOS

thegyro · 2013-12-13 12:47:17

Hi!

i just finished the basic installation of Arch Linux on My Acer Aspire V5 Netbook. After the basic installation , I installed the X Display Server , ATI Video Card Driver , XFCE Desktop Environment and LightDM Display Manager. Now I reboot my netbook , I get this error telling "kvm disabled by the bios" and everything halts. On Googling ,some suggested to turn "Virtualization" on from the BIOS set up. But I don't see any such option in the F2 setup screen. So please help!

you have it at 1:48 (but I really don't think that halts your system.

Hi! Thanks for the reply! But I don't have such advanced options in my BIOS screen. All I have is Information,Main,Security,Boot,Exit. I did not have any problem initially ,I was able to install Arch Linux successfully and reboot the laptop..I was able to login as root and everything worked fine. Why am I not able to do that now ?

The system didn't halt actually. I used Alt-F2 and was able to login as root in another screen. But if I press Alt-F2 again , I go back to the screen where I get the problem "kvm disabled by the BIOS"

Contact acer support and ask then how to enable it?

But why didn't I get a similar error as soon as I finished installing Arch on it ?

Probably because the kvm module is not being loaded.

I have seen the error in past but arch would run fine.

My Arch is running fine ,though the error KVM disabled is still there at the back . Is this a problem I should worry about or can I just neglect it ? What is the purpose of this module ?

if you're not using virtualization it probably doesn't matter

I've seen this message many, many times on different machines, and it's never caused any problems. The KVM module is in the stock Arch kernel; unless you have the vendor-specific virtualization stuff enabled in the BIOS/EFI setup menu, the KVM module won't load. The message is just telling you you can't use KVM on your system, which only matters if you really, really want to use KVM on your system.

EDIT---@OP: Since this is a new installation, have you ensured that you're booting into the correct target/runtime?

I am sorry but what does booting into the correct target/runtime mean ? Which is the correct one and how do I check it ?

By default, the system boots into multi-user.target, dropping the user at the command line after boot. If you're trying to boot into LightDM and log in from there, you'll need to enable lightdm.service (if you haven't already) and set systemd to boot into graphical.target instead. It may be the case that systemd is starting lightdm.service (if you enabled it), but booting into multi-user.target; hence the blank screen on TTY1, but login prompt on other TTYs.

If you are at all familiar with the old SysV way of doing things, then the target would be equivalent to /etc/inittab's runlevels. Use the search engine of your choice to learn more about systemd targets (and systemd units in general). Of course, systemd has great documentation as well, so you could reference the man pages too.

Basically what everyone is trying to tell you here is that the error, which you seem to have concluded is the root of your issue here, most likely has nothing to do with your inability to boot. You need to access the system's journal and see if you can determine what exactly is preventing the machine from coming up properly.
