HELP: kvmgt module cannot be loaded

[everwisher]

Proxmox version: 7.1
Kernel version: 5.13.19-6-pve

Symptom: kvmgt module cannot be loaded as lsmod|grep kvmgt returns nothing whereas both i915.ko and kvmgt.ko can be found in /lib/modules/<each kernel version>/kernel/drivers/gpa/drm/i915/

Configurations 1: /etc/modules:
kvmgt and vfio_mdev has been added in addition to regular vfio modules for iommu_type1 passthrough. While mdev and vfio_mdev modules can be returned from lsmod, kvmgt is not seen in the list.

Configurations 2: /boot/grub/grub.cfg:
Both i915.enable=1 and i915.enable_guc=0 has been added to kernel parameters while i915 driver is not disabled in kernel parameters nor in conf files in modprobe.d/

Btw, no errors associated to virtualization were logged in dmesg

Please post the full pveversion -v output.

both i915.ko and kvmgt.ko can be found in /lib/modules

Seems fine here:

:~$ find /lib/modules -name i915.ko
/lib/modules/5.13.19-5-pve/kernel/drivers/gpu/drm/i915/i915.ko
/lib/modules/5.13.19-6-pve/kernel/drivers/gpu/drm/i915/i915.ko
:~$: find /lib/modules -name kvmgt.ko
/lib/modules/5.13.19-5-pve/kernel/drivers/gpu/drm/i915/gvt/kvmgt.ko
/lib/modules/5.13.19-6-pve/kernel/drivers/gpu/drm/i915/gvt/kvmgt.ko

What's the output of above for you, did you actually check with modinfo or tried to load those modules using modprobe?

modinfo i915
modinfo kvmgt

I would like to pick this up as I am in the same situation.
