There are six steps to correctly configuring SNMP on your Citrix Xen hypervisor. These steps don’t require a system restart and are non-service affecting.
To start, we assume you’re running Xen v6.x or v7.x, and are logged into the Xen CLI as root.
1. Enable the SNMP daemon
Enable the snmpd daemon by typing-
2. Configure the SNMP service
Make a backup of the snmpd.conf file. The default snmpd.conf file contains a lot of useful documentation for more advanced implementations of SNMP.
# cp /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.backup

From the XenServer Command Line Interface (CLI), issue the following command:
Note: If you have more than one XenServer in the pool, you must issue the xe host-list command to list all the XenServer hosts and write down the Universally Unique Identifier (UUID) of the host that you added the new NIC, then issue command xe pif-list host-uuid=[uuid of the XenServer host]
The preceding command lists all the physical NICs of that XenServer. If you do not see the additional NIC, you must scan for new physical interface(s) on a XenServer and issue this command:
xe pif-scan host-uuid=[uuid of the XenServer host]
Press Enter. Continue reading “How to Add Additional Physical NICs to XenServer” »
XCP-NG + Xen Orchestra Community Edition = a powerful 100% free virtualization environment and backup solution. I’m writing this to provide hand holding for those interested in XCP-NG but intimidated by the required command line setup to get Xen Orchestra Community Edition (XOCE) working.
The installation and update scripts for Xen Orchestra were written by DustinB3403; I’m using information from a few different sources to make an easy to follow guide.
For the purposes of this guide I’ll presume you already have XCP-NG installed and that XOCE will be running as a VM on XCP-NG. I’ll also assume you already have XCP-NG Center installed on a Windows OS. You can download XCP-NG Center at https://github.com/xcp-ng/xenadmin/releases.

Step 1: Download Linux ISO
I used Ubuntu Server 18.04 LTS (http://releases.ubuntu.com/18.04/). If you’re not comfortable with Linux I suggest you do the same so you can use the same commands without modification. Otherwise, feel free to use your own flavor. Download the Linux ISO and save it in a shared windows folder. Continue reading “Setup Xen Orchestra (XO) Community Edition” »
