[ovirt-users] chrony or ntp ?

I haven't switched from ntp to chrony. So I have configured my puppet to remove it as it's now part of default installation of rhel. I works well with everything except on vdsm, since last upgrade: # yum erase chrony .. Removing for dependencies: vdsm x86_64 4.19.15-1.el7.centos @ovirt-4.1 2.6 M vdsm-hook-vmfex-dev noarch 4.19.15-1.el7.centos @ovirt-4.1 21 k Why vdsm depends on chrony ? Any time synchronisation solution is good. Is that the role of ovirt to chose for me ?
