[Solved]kvm not working with latest kernel

All of a sudden all my VMs created using virt-manager stopped working with error

Error launching details: Host does not support domain type kvm with machine 'pc-q35-7.2' for virtualization type 'hvm' with architecture 'x86_64'

svm mode is on in bios, on debugging more, it seems kvm_amd module failed to load at startup. When i try to load using modprobe i get,

modprobe: ERROR: ctx=0x55568ad972a0 path=/lib/modules/6.2.10-arch1-1/kernel/virt/lib/irqbypass.ko.zst error=No such file or directory

dmesg have a bunch of errors regarding kvm

[  207.063868] kvm_amd: Unknown symbol kvm_skip_emulated_instruction (err -2)
[  207.063871] kvm_amd: Unknown symbol kvm_set_or_clear_apicv_inhibit (err -2)

no such issue with linux-lts

Re: [Solved]kvm not working with latest kernel

Please post the output of

pacman -Qkk linux 

If it shows 0 altered files also post the dmesg & journal (run both with root rights) of  a boot with linux .

Re: [Solved]kvm not working with latest kernel

An interrupted kernel install (by a power failure or similar) could cause this . It should leave some trace in /var/log/pacman.log .

Another possibility are drive or filesystem issues. Check the journal for the time around the last linux kernel install before the failures.
