Hi oVirt 3.5 install hypervisors with the fence-agents package which has a certain list of supported power management (PM) cards in oVirt 3.5 if you want to add custom PM card in addition to the supported PM cards you should follow http://www.ovirt.org/Custom_Fencing Basically once you write your own script and install it on each host where fence-agents package is installed and modify oVirt configuration as described in the wiki, you should be able to see your custom agent in the list and use it. Please let me know if you need any further assist with that CCing also Marec G who is in charge of the fence-agents package Thanks Eli ----- Original Message -----

I would like to implement Power Management using an Eton E5 UPS, if this is not possible then I would like to know what UPS systems can be easily used with oVirt.
Can someone point me to information on how to configure the UPS, CentOS 6.5 (preferably), and oVirt to use the UPS system, so that I could purchase, install and implement the UPS.
If anyone has information regarding UPS, please reply to this email with links to the information.
Can oVirt use "Network UPS Tools (NUT)" for Power Management ? If so, is there any documentation on this subject that you could provide links to, please.

So far the most common statement I have found is "Ignore the warning about power management", but this is not what I want to do. http://www.r11networks.com/2013/04/ovirt-installation-guide/
