Can anyone explain the "CPU Units" In a VM configuration? What is a "unit" and how many of 'em do we need? In the attached image we see a value of 120050 - what does this mean? Is it a default value, and if so, how much "bang" for our CPU "buck" does this get us?
Asking the question another way:
Is there a way to obtain the total CPU cycles available for a host machine? Under those circumstances we would do a "back of the envelope" calculation as to how many of those CPU cycles to assign to any given VE.
(Example: a dual quad core 2.50 GHz Xeon machine CPU has 8 cores available, how many CPU cycles is that in total?)
Also:
In our "virtual machines" display, the CPU usage of all our VM's stands at zero. But ssh'ing into a particular vm shows - of course - that it is using CPU. Surely the interface can't be failing to grab utilization? If it turned out that it is failing to do so, how could we correct this? (assumption: we've done something wrong somewhere)
I'm wondering if these two are, broadly speaking, in some way connected.
