Hello,
I would like some help understanding CPU shares. We have several VMs which are CPU pinned
due to licensing. We would like to favor one VM since it is our application VM over the
other VMs which it is pinned with. Would I set the CPU share on the one that needs to
priority to high or low?
In the documentation I see the following:
Specify CPU Shares. Possible options are Low, Medium, High, Custom, and Disabled. Virtual
machines set to High receive twice as many shares as Medium, and virtual machines set to
Medium receive twice as many shares as virtual machines set to Low. Disabled instructs
VDSM to use an older algorithm for determining share dispensation; usually the number of
shares dispensed under these conditions is 1020.
I currently have it set to high and I believe it is doing the opposite of what I want it
to do as the CPU steal percentage appears to be 10-15% over the other VMs which show no
CPU steal and are set to low. I'd like to confirm if I have this setup correctly or
not.
Thanks,
Nick
