On the opposite - ovirt supports up to v6 of gluster and in cockpit, you can setup your hyperconverged setup (on gluster) abd your hosted engine ontop.

[ovirt-users] Re: ifcfg-bond0 getting overwritten.
Thanks All!
Ok, so configured auditd to watch /etc/resolv.conf and that pointed out
the problem.
A host that was reverting my changes had these /etc/resolv.conf* files:
[root@mdskvm-p01 etc]# grep -EiR "# Generated by NetworkManager" *
grep: extlinux.conf: No such file or directory
resolv.conf:# Generated by NetworkManager
resolv.conf.save:# Generated by NetworkManager # <<<
[root@mdskvm-p01 etc]#
[root@mdskvm-p01 etc]# grep -Ei search resolv.conf resolv.conf.save
resolv.conf:search mds.xyz nix.mds.xyz mws.mds.xyz
resolv.conf.save:search mds.xyz
[root@mdskvm-p01 etc]#
and a host where changes to /etc/resolv.conf were not occurring, had
these files (note the missing .save file):
[root@mdskvm-p02 etc]# grep -EiR "# Generated by NetworkManager" *
grep: extlinux.conf: No such file or directory
resolv.conf:# Generated by NetworkManager
resolv.conf-original:# Generated by NetworkManager
[root@mdskvm-p02 etc]#
The reason why /etc/resolv.conf was reverting on the first host is
because there is a line in the following ifdown-post network script that
overwrites /etc/resolv.conf from /etc/resolv.conf.save, if you have it:
[root@mdskvm-p02 network-scripts]# vi ifdown-post
.
.
.
# Remove duplicate DNS entries and shift them,
# to have always correct condition below...
update_DNS_entries
if ! is_false "${PEERDNS}" || is_true "${RESOLV_MODS}" && \
[ "${DEVICETYPE}" = "ppp" -o "${DEVICETYPE}" = "ippp" -o -n "${DNS1}" \
-o "${BOOTPROTO}" = "bootp" -o "${BOOTPROTO}" = "dhcp" ] ; then
if [ -f /etc/resolv.conf.save ]; then # <
change_resolv_conf /etc/resolv.conf.save
rm -f /etc/resolv.conf.save# <
fi
if [ "${DEVICETYPE}" = "ppp" -o "${DEVICETYPE}" = "ippp" ]; then
if [ -f /etc/ppp/peers/$DEVICE ] ; then
rm -f /etc/ppp/peers/$DEVICE
fi
fi
fi
.
.
.
.
And the function change_resolv_conf() effectively copies the contents of
/etc/resolv.conf.save over /etc/resolv.conf thereby overwriting anything
in it, if it exists (See # <<<
markers below ):
[root@mdskvm-p02 network-scripts]# vi network-functions
# Invoke this when /etc/resolv.conf has changed:
change_resolv_conf ()
{
s=$(/bin/grep '^[\ \ ]*option' /etc/resolv.conf 2>/dev/null)
if [ $# -gt 1 ]; then
if [ "x$s" != "x" ]; then
s="$s"$'\n'
fi
n_args=$#
while [ $n_args -gt 0 ]; do
case "$s" in
*$1*)
shift
n_args=$(($n_args-1))
continue
;;
esac
s="$s$1"
shift
if [ $# -gt 0 ]; then
s="$s"$'\n'
fi
n_args=$(($n_args-1))
done
elif [ $# -eq 1 ]; then
if [ "x$s" != "x" ]; then
s="$s"$'\n'$(/bin/grep -vF "$s" $1)
else# <<<
s=$(cat $1)
fi # <<<
fi
(echo "$s" > /etc/resolv.conf) >/dev/null 2>&1; # <
r=$?
if [ $r -eq 0 ]; then
[ -x /sbin/restorecon ] && /sbin/restorecon /etc/resolv.conf
>/dev/null 2>&1 # reset the correct context
/usr/bin/logger -p local7.notice -t "NET" -i "$0 : updated
/etc/resolv.conf"
[ -e /var/run/nscd/socket ] && /usr/sbin/nscd -i hosts #
invalidate cache
fi
return $r
}
So you have to modify both files in order to persist the changes or
simply remove the /etc/resolv.conf.save file. Appears when some
older interface parameters were used before I installed oVirt here, they
triggered creation of the .save file. Because it exists, it's simply
used by default. Hence why changes directly to /etc/resolv.conf
persisted on the second host: it didn't have a /etc/resolv.conf.save file.
Cheers,
TK

If the config does really get overwritten, it probably means that more

If indeed what you are looking for is to add a dns search line, you
should add it to /etc/resolv.conf.

You can check your other hosts for any differences there.
It is recommended that networks are set up and managed through ovirt
engine.

This depends if you use NetworkManager.service for other connections. If you don't use NetworkManager , then that's a working approach.
