Hahaha :D, pardon, "KMS" most likely is from "DKMS", just the "K" is
missing. But, the rest still might be correct. Did you try to boot the
kernel? I suspect it is installed, just running VMware might fail.
Assuming just a header package wasn't installed, simply reinstall the
kernel package, after the the headers are installed, or run DKMS
manually from command line.
