Description Rami Vaknin 2012-06-19 11:15:33 UTC

Environment:
RHEV-M SI4

Scenario:
I've installed 36 hosts with power management configuration using python sdk script.
Each host installation followed by power management configuration which done right after the host installation has started.

The issue is that in each cycle of running that script - all the hosts are installed successfully however there are always several hosts (different hosts in each cycle) that fail to get updated with the power management configuration.

From engine.log:

Verified on SI21.
I've installed 38 hosts with power management using the same script, all of them passed successfully.
