I enable vmx and svm option for KVM in .config
on amd SVM enable system
vmx get tried at first
and get

kvm: no hardware support
Calling initcall 0xffffffff80c2d465: vmx_init+0x0/0x119()

kvm: no hardware support

initcall 0xffffffff80c2d465: vmx_init+0x0/0x119() returned -95.

suggest you add .name in ops like "vmx" or "svm"
and that message can become

kvm: no hardware support for vmx

or

kvm: no hardware support for svm
or just remove that line.

        }
        if (!ops->cpu_has_kvm_support()) {

-                printk(KERN_ERR "kvm: no hardware support\n");

                r = -EOPNOTSUPP;

                goto out;

        }
