Firstly we set the XenServer root partition to 16GB (opposed to the default 4GB, which is kinda tight), see Major IO blog;

F2 on install
vi /opt/xensource/installer/

Change the following lines;

line #89


Line #92

root_size = 16384

Update the XenServer, see How to install XenServer 6.5 patches

Install the Dell OMSA software on the XenServer partition.

Step 1: Temporarily disable the Citrix yum repository. As of this post, Citrix’s repo does not seem to be working properly.

To do so, let’s temporarily move the Citrix.repo file out of the /etc/yum.repos.d folder.
Alternatively, you can also disable the repo within the file itself.

mv /etc/yum.repos.d/Citrix.repo /root/Citrix.repo

Step 2: Run the following:

yum clean all

Step 3: Install the latest supported Dell OMSA Repository:

wget -q -O – | bash

Step 4: Install Dell OpenManage Server Administrator

yum –enablerepo=base install srvadmin-all -y

Step 5: Open port 1311 in iptables

nano /etc/sysconfig/iptables

Now add the following line above the last line which says icmp-host-prohibited:

-A RH-Firewall-1-INPUT -m conntrack –ctstate NEW -m udp -p udp –dport 161 -j ACCEPT
-A RH-Firewall-1-INPUT -m conntrack –ctstate NEW -m tcp -p tcp –dport 1311 -j ACCEPT

Step 6: Restart iptables

service iptables restart

Step 7: Start Dell OpenManage Server Administrator

/opt/dell/srvadmin/sbin/ start

Step 8: Move the Citrix.repo file back to the original location:

mv /root/Citrix.repo /etc/yum.repos.d

Step 9: You can now access OMSA via your favourite browser:
