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 ?

Adding people involved in this change.
Please note the change has been reviewed and discussed on
https://gerrit.ovirt.org/#/c/73822/ for addressing
https://bugzilla.redhat.com/show_bug.cgi?id=1428419
and it moves from requiring ntp to requiring chrony.
So it was already deciding for you, you just both were in agreement :-)
Sadly:
# rpm -q --provides ntp
config(ntp) = 4.2.8p10-1.fc26
ntp = 4.2.8p10-1.fc26
ntp(x86-64) = 4.2.8p10-1.fc26
rpm -q --provides chrony
chrony = 3.1-4.fc26
chrony(x86-64) = 3.1-4.fc26
config(chrony) = 3.1-4.fc26
there's no way to require just the time synchronization capability like in
httpd providing the webserver capability:
# rpm -q --provides httpd
config(httpd) = 2.4.25-8.fc26
httpd = 2.4.25-8.fc26
httpd(x86-64) = 2.4.25-8.fc26
httpd-mmn = 20120211
httpd-mmn = 20120211x8664
httpd-suexec = 2.4.25-8.fc26
mod_dav = 2.4.25-8.fc26

In Fedora we may use boolean dependencies and install chrony only if ntp is
not already installed: http://rpm.org/user_doc/boolean_dependencies.html
but this feature is not available in RHEL / CentOS.
I let others explain why we are enforcing the dependency on the package
itself instead of moving vdsm to an error state if time synchronization is
disabled at runtime:

You can just disable the chrony service(we rely on the fact it=E2=80=99s =

People might be suprised. I'm currently trying to understand what chrony did to my
ntpd setup, it look like it killed it and puppet has hard time to reconfigure it.
And as it's not a 'ovirt update' but instead vdsm update seems to happen more
frequently, some people might forget to read release notes and be disappointed.

We do not configure anything. Just pull in dependency. You're free to
disable the service as a common admin task. As long as you replace it
with other time synchronization solution

Yes, that's I've done, but beware of user complain about broken ntp service
because their specially crafted ntpd configuration now lying dead. I detected it because
my puppet setup tried to uninstall chrony and failed. What about other users ? Does the
default chrony settings always works, for every one ?

Since you mentioned puppet, here's out puppet pp and template erb we use, hope
it help. IMHO, ntp has problems that chrony doesn't have:
chrony/manifests/init.pp:

$stratumweight = 0,

$iburst_enable = true,
$rtcsync_enable = false,) {

Other strange dependencies:
rpm -q --requires vdsm
returns:
sos
tree
NetworkManager-config-server
I don't use NetworkManager-config-server and never used it. There is just this lonely
components.
I'm running Centos, not Redhat, what 'sos' is good for in this case ?
tree is for interactive shell, who can a python application needs it ?
There is a lot of other tools like openvswitch's and iscsi's that are not used in
my setup. But I can understand that they are always installed. A modular approach would
have been better but much more complicated to implement.
which, every one use it , even if it's not the best solution instead of the bash
builtin 'type -p' (bash is part of the requires) or more portable 'command
-v', it's all explained at: https://unix.stackexchange.com/a/85250. But I must
live with this.

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 ?

vdsm ships a sos plugin for collecting logs useful for debug issues. Here
the dependency on sos is needed for ensuring the directory tree owned by
sos is in place for installing the plugin.
Also, ovirt-log-collector assumes sos is installed on the hosts.
Yes, sos is still useful, I often ask users to provide a sos report in
order to understand what's going wrong.
tree is for interactive shell, who can a python application needs it
?
tree is needed by vdsm sos plugin, see https://gerrit.ovirt.org/#/c/555/
