Hi,

These parameters were not configured, but after configuring them
as mentioned status of hosts in onehost list changes to Err.
In one of the machine i have set
user=oneadmin,
group=oneadmin,
dynamic_ownership=0

for this machine host statues is Err and in oned.log it shows this:
Sat Apr 13 15:38:02 2013 [InM][I]: Monitoring host anant-Inspiron-N5010 (2)
Sat Apr 13 15:38:02 2013 [InM][I]: Command execution fail: 'if [ -x

anant-Inspiron-N5010; else                              exit 42; fi'

Sat Apr 13 15:38:02 2013 [InM][E]: Error monitoring host 2 : MONITOR

To me it seems libvirt does not start if i change user to oneadmin.
Thanks,
