You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Fix:
yum --disablerepo=* --enablerepo=base install vdo kmod-kvdo
centos 7 openvz
yum install epel*release
yum install prlctl prl-disp-service vzkernel
reboot
systemctl status vz

You should check ovz kernel version: uname -a
if you have 2.6.32-042stab108.8 you should upgrade kernel up to 2.6.32-042stab120.11
