Cannot load kvm_amd module - (says disabled by bios)
All,
this is a bug with KVM, impacting (at least) all mainstream kernels that I tried so far: 3.2, 3.3, 3.4, 3.5, 3.8, 3.10 and 3.11
This is the link of the downstream bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1201092
- Firt of all I mention that this bug has been raised also for Fedora 18.
Here is the link: https://bugzilla.redhat.com/show_bug.cgi?id=978608
- I am running Ubuntu Raring (with the kernel 3.8.0-27-generic), but I've also tried the mainstream kernel (without Ubuntu patches).
- It happens with the following CPU: AMD E-350D
- The kvm-ok executable says that the system is capable of running KVM, but it also says the it's disabled in the BIOS.
- This is the out put of kvm-ok:
# kvm-ok
INFO: /dev/kvm does not exist
HINT: sudo modprobe kvm_amd
INFO: Your CPU supports KVM extensions
INFO: KVM (svm) is disabled by your BIOS
HINT: Enter your BIOS setup and enable Virtualization Technology (VT),
and then hard poweroff/poweron your system
KVM acceleration can NOT be used- This is what modprobe kvm-amd says:
# modprobe kvm-amd ERROR: could not insert 'kvm_amd': Operation not supported root@yasna:~# dmesg |tail -n1 [ 2542.263745] kvm: disabled by bios
- AMD-V extension on Virtualbox works correctly.
Therefore the extension works properly but it's not recognized by KVM.

Cordiali saluti / Kind regards Massimiliano Adamo

All,
this is a bug with KVM, impacting (at least) all mainstream kernels that I tried so far: 3.2, 3.3, 3.4, 3.5, 3.8, 3.10 and 3.11
This is the link of the downstream bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1201092- Firt of all I mention that this bug has been raised also for Fedora 18.
Here is the link: https://bugzilla.redhat.com/show_bug.cgi?id=978608- I am running Ubuntu Raring (with the kernel 3.8.0-27-generic), but I've also tried the mainstream kernel (without Ubuntu patches).
- It happens with the following CPU: AMD E-350D
- The kvm-ok executable says that the system is capable of running KVM, but it also says the it's disabled in the BIOS.
- This is the out put of kvm-ok:
# kvm-ok INFO: /dev/kvm does not exist HINT: sudo modprobe kvm_amd INFO: Your CPU supports KVM extensions INFO: KVM (svm) is disabled by your BIOS HINT: Enter your BIOS setup and enable Virtualization Technology (VT), and then hard poweroff/poweron your system KVM acceleration can NOT be used
Quoted 8 lines
- This is what modprobe kvm-amd says:
# modprobe kvm-amd ERROR: could not insert 'kvm_amd': Operation not supported root@yasna:~# dmesg |tail -n1 [ 2542.263745] kvm: disabled by bios- AMD-V extension on Virtualbox works correctly.
Therefore the extension works properly but it's not recognized by KVM.
What evidence do you have that Virtualbox is actually making use of AMD-V?

All,
this is a bug with KVM, impacting (at least) all mainstream kernels that I tried so far: 3.2, 3.3, 3.4, 3.5, 3.8, 3.10 and 3.11

Hi! That's a good point.
Right now I can only say "it was selectable from the GUI". Therefore I just imagined "it's recognized".
Now I try to see how to enable/check logs on Virtualbox and I'll get back to you with some feedback.

Hi,
logs are enabled by default and they say that the extension might be disabled even for Virtualbox:
00:00:01.406771 SVM - AMD VM Extensions = 0 (1)
00:00:01.406945 HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_SVM_DISABLED
(therefore, it let's you enable the AMD-V feature, because it's found on the CPU but it's not able to use it).
And I've found a suggestion to run the commands below:
# rdmsr -f 12:12 0xc0000080 # If set (1), SVME is enabled. 0 # # rdmsr -f 4:4 0xc0010114 # If set (1), it is disabled. 1
If I will have time, I would try installing Windows on a spare partition, and then try running virtualbox there (and check logs). If you have a better advice, or any other idea, please just let me know.
p.s.: CC-ing the person who is facing the same issue with Fedora.

It looks like your BIOS is broken, contact the vendor. You might try setting it to disabled in the BIOS to make sure it's not wired backwards. There also used to be some FUD about fully powering off the system around making changes to these settings. You might try unplugging the system for a few seconds and testing from there. Thanks,
Alex
