I have a CentOS 6.4 (32bit x86) VPS, which runs on XEN and on which I decided to install OpenVZ kernel (yum install vzkernel) and tools (yum install vzctl ploop). After a reboot it kind of loaded successfully, except that I now see this error in /var/log/messages at every reboot and system calendar and clock is messed up until ntpd synchronization,

Oct 8 05:41:53 xodev01 kernel: [ 0.118591] rtc_cmos: probe of rtc_cmos failed with error -16
Oct 8 05:41:53 xodev01 kernel: [ 0.120007] drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

Modprobe seems to indicate it is missing,

[root@xodev01 ~]# modprobe rtc-cmos
FATAL: Module rtc_cmos not found.

[root@xodev01 ~]# uname -a
Linux xodev01 2.6.32-042stab081.3 #1 SMP Mon Sep 9 19:55:30 MSK 2013 i686 i686 i386 GNU/Linux

[root@xodev01 ~]# rpm -aq | grep "^vz"

If you need more information just let me know (I'm not sure so none for now).

I use yum priorities (CentOS repositories have the highest priority of 1) and EPEL. Maybe this could have somehow interfered with the installation, but I struggle to think how.

Please advise.

Thank you in advance.

Kind regards,

You're running openvz inside a xen vm, which is... well, interesting.

I think yum priorities didn't affect your install in any way. Unless there are actual consequences to these RTC errors, I wouldn't worry about them.
