Did you modprobe kvm and either kvm-intel or kvm-amd?

Aegidius · 2012-03-15 11:05:19

how can i do that?

For KVM see here: https://wiki.archlinux.org/index.php/KVM (note it has an Italian page)
Also see here: https://wiki.archlinux.org/index.php/Qemu (unfortunately no Italian page)

thank you

i get this error

[egidio@localhost ~]$ sudo modprobe kvm-amd
ERROR: could not insert 'kvm_amd': Operation not supported

What is the output of this?

grep -E "(vmx|svm)" --color=always /proc/cpuinfo

Also see this bit of the kvm page:

If modprobing kvm succeeds, but modprobing kvm-intel or kvm-amd fails (but /proc/cpuinfo claims that hardware acceleration is supported), check your BIOS settings. Some vendors (especially laptop vendors) disable these processor extensions by default. To determine whether there's no hardware support or there is but the extensions are disabled in BIOS, the output from dmesg after having failed to modprobe will tell.

VT is enabled in the BIOS.

I'm a bit stuck then. I use intel and those steps all worked for me (as far as I remember), so I'm not sure what else it could be.
Just to be sure, you did modprobe kvm first, didn't you? Are you running the standard kernel? If not check that it supports kvm.

You may find more info. here http://www.linux-kvm.org/page/Main_Page I'd look for your specific processor to see if there's anything that needs to be done.

I am a little unsure on your first qemu command. I thought you needed qemu-kvm for it to require kvm, or at least run with -enable-kvm. It was a year or so ago that I set it up though, so I may be out of date.

My teacher says to install kvmmode, but I don't know how to do it

Can you please help me? I have got the laptop in my signature.

You have an Intel chip so run this command:

sudo modprobe kvm-intel

Aegidius · 2012-03-22 08:36:46

I solved adding kvm-intel to MODULES array in /etc/rc.conf. You should restart PC.

Or just run modprobe instead of rebooting, anyway good that you solved it!
