Kernel panic when loading kvm-amd

Kernel panic when loading kvm-amd

[Pär Andersson]

[-- Attachment #1.1: Type: text/plain, Size: 893 bytes --]

Hi.

I am getting a kernel panic when loading the kvm-amd module. I have talked a 
little about this with aliguori on IRC and according to him the panic occurs 
when KVM enables EFER.SVME.

Computer information:
AMD Athlon64 X2 4400+, 65nm, Brisbane.
Abit KN9 motherboard (nforce4)
Ubuntu 7.04 x86_64
Kernel version 2.6.20-15-generic (latest Ubuntu kernel for 7.04)

Unfortunately my motherboard does not have rs232 so I can't attach a serial 
console to get the text of the panic. Instead I have taken a photo of the 
screen, not very good but it is the best I can do. This "screenshot" together 
with some more hardware information (output from dmesg, /proc/cpuinfo etc) is 
here:

http://www-und.ida.liu.se/~paran213/kvm/2007-05-27/

The screenshot is when using KVM-25, I get the same result using KVM-16(from 
ubuntu packages) and KVM-24.

regards
Pär Andersson

I find this very odd.  Setting EFER.SVME shouldn't do any harm even if 
it's already set.  The only thing I can think of would be that SVM 
wasn't available but this is an X2 so it really ought to be.

Anyone have any clue why setting EFER.SVME would cause an OOPS?

SVM looks available on your machine. If possible, could you provide dmidecode information (type "dmidecode") for further verification? I know that some vendors disabled SVM feature in BIOS last year. But this was pretty rare. Maybe you can check whether BIOS has an option for SVM.

Is there a way to detect whether the bios has disabled svm?  If not, is
trapping the #GP on wrmsr(EFER) a good way to do it?

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Re: Kernel panic when loading kvm-amd

[Huang2, Wei]

As far as I know, there is no special way to detect BIOS-disabled SVM. BIOS should always trap #GP on writing SVME bit. So the way you suggested should work.

Pär, are you sure that EFER.SVME bit has been set when the error happened? Our architecture design team confirmed that enabling EFER.SVME twice won't cause any problem (There will be some performance loss though).

Okay.  How does the bios disable svm?

No, I am not sure, this is a bit above my level of knowledge. The EFER.SVME 
interpretation was from Anthony when he looked at the panic output.

Output from dmidecode is attached. Please tell me if there is anything else 
you need.

I will take a look in the BIOS again, but I don't remember any virtualization 
options. I am also planning on doing some tests with some other linux 
distribution to rule out the possibility of this being a bug in Ubuntus 
kernel.

Testing with other Linux distributions was already on my TODO list as I 
mentioned before. However this won't be necessary any more as I yesterday got 
KVM to work with my normal kernel. :-)

I went through my BIOS settings and found:
"Advanced BIOS Features" -> "CPU Feature" -> Virtualization

However this was already set to "Enabled". I tried changing the value 
to "Disabled" and now KVM works fine. Stupid ABIT...


If you try to change KVM to detect BIOS disabled SVM (or Enabled, in ABITs 
case...) instead of panicing I will be glad to help test that.
