Clustered Oracle VM server 2.1.2 won't reboot or hangs

Question

Has anyone experience with clustered Oracle VM servers 2.1.2 seem to be hang or won't reboot until the server is power reset?
Every time I reboot the master pool server, the server seems to be hung or won't reboot. To solve this problem I have to power reset the server or reboot the other server in the server pool or vice versa. This is not what I wanted. What do i need to do to have a smooth reboot of master server pool without reboot the other server in the server pool?
Thank you in advance.

Hi Avi,
There is no entries logged after issuing the reboot command on ovm-s-2 or ovm-s-1.
SSH session #1
[root@ovm-s-2 network-scripts]# reboot
It hangs right here
SSH session #2
[root@ovm-s-2 ~]# tail -100 /var/log/messages

The /OVS should not be still mounted. If it does, it should be like this, right?
FROM ovm-s-1 the master server pool.
