ok, so moments after i sent that question, i finally stumble onto the RHEV =
documentation, and it states that the setting is for CPU load, and you spec=
ify what % and how many minutes its allowed to stay that way before no new =
VMs are allowed to start on the host.
but still leaves the question, what about memory resources and how are they=
governed as far as automatic migrations go?
thanks,
jonathan

Subject: [Users] General: Edit Policy
today i just saw for the first time Clusters =96 General: Edit Policy butto=
n. i changed it from nothing to balanced. googling, it seems that this is=
for CPU load amongst the hosts to balance the CPU load of VMs. the reason=
I'm asking is, my test environment is 3 hosts, and 2 of them are leveled u=
p to above 75% memory usage (both of them complaining on the events console=
), and nothing migrating to the 3rd node which currently has 0 VMs.
do i have something incorrectly configured? i was under the assumption that=
migrations would happen automatically when host resourced were nearing max=
(i assumed this was either CPU or memory)? on my cluster, i checked the s=
etting for memory optimization for servers.
is there anything else? am i not properly understanding the migration theo=
ry? my "guide" link in the upper right does not hyperlink to any docs, so =
I'm left to google and i have not found much so far.
thanks for any advice,
jonathan
