Libkmod honors ‘modprobe.blacklist’ (in ‘kcmdline_parse_result’ in
libkmod-config.c) and eudev passes KMOD_PROBE_APPLY_BLACKLIST
unconditionally in udev-builtin-kmod.c (meaning it honors it too.)
However, there’s a hyphen-vs-underscore issue, I think. Namely, the
file is called ‘kvm-intel.ko’, but the normalized module name is
‘kvm_intel’, and this is what libkmod expects (commit 5c7dd5a changes
our code to normalize module names similarly.)
Could you try with “modprobe.blacklist=kvm_intel”?
TIA,
Ludo’.
