I'm not sure why it's asking for vdsm-client >= 4.18.6

I've got the following vdsm rpms installed:

vdsm-4.19.4-1.el7.centos.x86_64
vdsm-api-4.19.4-1.el7.centos.noarch
vdsm-cli-4.19.4-1.el7.centos.noarch
vdsm-hook-vmfex-dev-4.19.4-1.el7.centos.noarch
vdsm-jsonrpc-4.19.4-1.el7.centos.noarch
vdsm-python-4.19.4-1.el7.centos.noarch
vdsm-xmlrpc-4.19.4-1.el7.centos.noarch
vdsm-yajsonrpc-4.19.4-1.el7.centos.noarch

Still missing vdsm-client in the list.
