[ovirt-users] [Ovirt 4.0] HA VM fail to start on another Host.

[TranceWorldLogic .]

Hi,

VM have guest agent install but power management is disable.

Just want to confirm my understanding "HA will not work without power
management", please say yes or no.

We have Dell server and it access through idrac, I am not sure how to setup
power management for idrac.
I tried with drac5 and drac7 and both case while testing I got error saying
*"*
*Test failed: [Connection timed out, , ]"*
But ping is working from ovirt-engine.

Would you please point me to some link how to setup power management for
DELL idrac ?


Thanks,
~Rohit
