[SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

So i was trying to run virtual machines using kvm. When i opened virt-manager it showed KVM is not available so i ran:

lsmod | grep kvm

It had no output.

So i tried manually loading the module and got this error.

sudo modprobe kvm
[sudo] password for Odd:

sudo modprobe kvm_amd
[sudo] password for Odd:
modprobe: ERROR: could not insert 'kvm_amd': Unknown symbol in module, or unknown parameter (see dmesg)

Here's dmesg output:

[  683.732469] kvm_amd: Unknown symbol allow_smaller_maxphyaddr (err -2)

Then i went into the bios to see if virtualization is enabled but couldn't find any option related to that there. So i found this command to check if it is enabled.

sudo LC_ALL=C lscpu | grep Virtualization
[sudo] password for Odd:
Virtualization:                     AMD-V

I tried running a VM, it was running but the performance was bad. Forgive me if i made any mistakes, i am new to linux and feel free to ask for anything from my side.

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

Are all the missing symbols in the output of `depmod -nv`?

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

Well there are too many symbols to check but i tried finding a few and they are in it's output:

sudo depmod -nv | grep "kvm_amd"
[sudo] password for Odd:
alias cpu:type:x86,ven*fam*mod*:feature:*00C2* kvm_amd

sudo depmod -nv | grep "kvm_vcpu_kick"
[sudo] password for Odd:
alias symbol:kvm_vcpu_kick kvm

sudo depmod -nv | grep "kvm_fast_pio"
[sudo] password for Odd:
alias symbol:kvm_fast_pio kvm

Is there a way to check for all the missing symbols ? Sorry i am relatively new.

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

Given that at least some of the symbols are there I would try updating the kernel module dependencies:

# depmod

A shot in the dark:

# pacman -Q linux
# uname -a

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

Ran the "depmod" command and it had no output so i am assuming it ran successfully. Then i rebooted. But virt manager is still showing KVM is not available

pacman -Q linux
linux 6.7.4.arch1-1

uname -a
Linux Odd 6.6.16-1-lts #1 SMP PREEMPT_DYNAMIC Mon, 05 Feb 2024 21:20:21 +0000 x86_64 GNU/Linux

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

If you rebooted, why isn't the current kernel running?
Did you not have /boot mounted when running the last update?
Check your /boot partition, reinstall the kernel appropriately and then reboot your machine to load the installed kernel (and its modules).
The currently installed module is not for your currently running kernel, but for the version you upgraded to.
Hence, it cannot be loaded for the outdated running kernel.
Oops, you appear to be running the LTS kernel.
Thank you @ loqs

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

He's on linux-lits 6.6.16-lts is technically correct. ... But this might anyway be something to test, does the same thing happen on the non LTS kernel?

FWIW lscpu lists what he cpu is capable of, not what is configured/enabled. You'd still need to check in your UEFI/BIOS, which mainboard is this?

and also

modprobe -v kvm_amd

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

install /bin/true

You blacklisted something.

modprobe -c | grep true

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

Well, yeah… you've blacklisted the module, therefore you cannot load it - at least not using modprobe… if this is the only blacklisting measure.

What's the point here?

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

ok i don't how i might have blacklisted it. But i removed them from the black list and the virt-manager error is gone. Thanks everybody.

Also i am not able to mark it as solved using my initial post. I am able to change the body but not the subject.

Re: [SOLVED] could not insert 'kvm_amd': Unknown symbol in module,

https://bbs.archlinux.org/edit.php?id=2150154 should allow you to edit the initial post and there's a subject line on the top.
The subject is probably too long, so you can't  add text, you'll have to shorten it a bit, like eg.

"[SOLVED] could not insert 'kvm_amd': Unknown symbol in module"
