RHEL7.7 dracut Failed to install module libnvdimmvmxnet3

I just upgraded one of my systems from RHEL 7.6 to 7.7. During the update, I got the following error: 
dracut[43998]: Failed to install module libnvdimmvmxnet3
The fix is this: in /etc/dracut.conf.d/*.conf -- in my case, both nvdimm-security.conf and vmware-tools.conf, edit the "add_drivers" line to add a leading and trailing space. e.g. in nvdimm-security.conf, change: 
add_drivers+="libnvdimm"
to 
add_drivers+=" libnvdimm "
and in vmware-tools.conf, change: 
add_drivers+="vmxnet3 vmw_pvscsi"
to 
add_drivers+=" vmxnet3 vmw_pvscsi "
Then, run "dracut --force" to rebuild your initramfs. You should no longer get the "Failed to install module libnvdimmvmxnet3" error. The reason for the problem is that dracut is concatenating all the "add_drivers" strings together, without any processing. See the dracut.conf man page for the warning that was apparently ignored by the open-vm-tools folks: "Space-separated lists have to have a leading and trailing space"

    Absolutely awesome guidance ... my VM refused to suspend and but I saw an error in /var/log/messages about missing adapter but could not figure out what has gone wrong. Update kernel and got this error about dracut .. now this has fixed both issues !!!
