Long time to boot RHEV guest Linux VM.

Trying to investigate on long boot time of a linux guest in RHEV Host.

Before executing init 6/reboot command , I noticed the time of shutdown and also recorded the time after boot .

It takes around 20-25 mins in booting.

In boot logs I can find the time stamps for the very first event is '18:14:38' , it is almost one minutes difference from the time after boot.

dev]$ date

From the serial console I see below output before shutdown n after boot:

Feb 25 17:50:35 Bdata-2 sudo: admusr : TTY=pts/0 ; PWD=/home/admusr ; USER=root ; COMMAND=/usr/bin/reboot

Feb 25 17:51:08 Bdata-2 kernel: Kernel logging (proc) stopped.

Feb 25 17:51:08 Bdata-2 rsyslogd: [origin software="rsyslogd" swVersion="5.8.10" x-pid="2715" x-info="http://www.rsyslog.com"] exiting on signal 15.

Feb 25 18:14:35 Bdata-2 kernel: imklog 5.8.10, log source = /proc/kmsg started.

Feb 25 18:14:35 Bdata-2 rsyslogd: [origin software="rsyslogd" swVersion="5.8.10" x-pid="2651" x-info="http://www.rsyslog.com"] start

For this 25 mins of window , I cant find any logs/events that indicates the reason for such a delay in boot.

Could anyone help here on what should I investigate to narrow down the cause of the issue?

syslog

SYSLOG(8)                                                         System Logging                                                         SYSLOG(8)

NAME

       syslog-ng, syslogd

DESCRIPTION

       There are different syslog daemon implementations supported as the system's syslog service, currently syslogd, syslog-ng and rsyslogd

       The  first  installed daemon activates itself for the syslog service. Starting with openSUSE-11.2, it is rsyslogd, before it was syslog-ng.
       But this depends on the software selection during the installation.

       The name of the daemon used as syslog service is specified in the
       SYSLOG_DAEMON variable in /etc/sysconfig/syslog.

       The yast2 sysconfig module provides a comfortable way to switch to another installed daemon and restart the service.

       The /etc/init.d/syslog init script is able to handle all supported daemons.
