For reference, the above is for linux-kvm 5.19.0-1019.20

This failure is due to the fact that the dkms configuration expects specific kernel modules built which in turn depend on specific kernel configuration for the running kernel. On linux-kvm, these dependencies are not met so building should be skipped.

This is snipped of the Kconfig dependency for IWLWIFI:

config IWLWIFI
        tristate "Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlwifi) "
        depends on m
        depends on PCI && HAS_IOMEM && CFG80211
        depends on IWLMEI || !IWLMEI
        depends on FW_LOADER
