I think in Fedora 18 itself and/or due to oVirt setup there is some conflict regarding network synchronization services.... In fact together with standard ntp there is chrony that I didn't know until today... My suspect is this one: - At install time Fedora 18 by default installs now chrony and doesn't install instead ntpd In fact my anaconda log in /root [root@f18ovn03 ~]# ll /root/anaconda-tb-38wvGO -rw-r--r--. 1 root root 1493714 Dec 18 14:27 /root/anaconda-tb-38wvGO contains: 14:19:00,759 DEBUG packaging: select package chrony and no entry for ntp At this moment chronyd was still enabled as per default at install time: [root@f18ovn03 ~]# systemctl status chronyd.service chronyd.service - NTP client/server Loaded: loaded (/usr/lib/systemd/system/chronyd.service; enabled) Active: inactive (dead) since Tue, 2013-01-22 14:15:42 CET; 9h ago Main PID: 1348 (code=exited, status=0/SUCCESS) CGroup: name=systemd:/system/chronyd.service Jan 22 14:15:40 f18ovn03.ceda.polimi.it chronyd[1348]: chronyd version 1.27-git1ca844 starting Jan 22 14:15:40 f18ovn03.ceda.polimi.it chronyd[1348]: Linux kernel major=3 minor=6 patch=11 Jan 22 14:15:40 f18ovn03.ceda.polimi.it chronyd[1348]: hz=100 shift_hz=7 freq_scale=1.00000000 nominal_tick=10000...ll=2 Jan 22 14:15:41 f18ovn03.ceda.polimi.it systemd[1]: Started NTP client/server.

So I have tested disabling chrony # systemctl disable chronyd and re-enabling ntp as a dependency for vdsmd to see if something changes: Changed /usr/lib/systemd/system/vdsmd.service matching: Requires=multipathd.service libvirtd.service ntpd.service Bingo!

I also modified ntp.conf commenting out #server 0.fedora.pool.ntp.org iburst #server 1.fedora.pool.ntp.org iburst #server 2.fedora.pool.ntp.org iburst #server 3.fedora.pool.ntp.org iburst and putting a "server xxx.yyy.www.zzz" line to an internal ntp server but I don't think this was influencing my problems To be sure anyway I reverted to old ntp.conf config with server 0.fedora.pool.ntp.org iburst server 1.fedora.pool.ntp.org iburst server 2.fedora.pool.ntp.org iburst server 3.fedora.pool.ntp.org iburst # server xxx.yyy.www.zzz And both ntpd and vdsmd started again and host up and SPM in webadmin. Probably another thing to take care of for Fedora 18 configured as an oVirt node. Gianluca
