Download vddk library
Login to Broadcom web link and download zip file.
Place it under /tmp/ on virt-v2v appliance. In my case I downloaded the latest version which is 8.0.3.
Move tar file under /opt and extract it
ls -l /tmp/VMware-vix-disklib-8.0.0-20521017.x86_64.tar.gz
mv /tmp/VMware-vix-disklib-8.0.0-20521017.x86_64.tar.gz /opt/
cd /opt
tar xvzf VMware-vix-disklib-8.0.0-20521017.x86_64.tar.gz
cd vmware-vix-disklib-distrib/
