Josh,
What I want to do is that make the workloads on each blade are equal. For
instance, there are 6 virtual machines running in the system which has 6
blades, I hope VCL can select a computer which belong to a host that has the
lowest current workload. So in the end, each virtual machine can be running
on different blades.
Thanks,
Xianqing

Xianqing,
The scheduling algorithm is in isAvailable in utils.php. It would be
difficult to describe the whole thing. Have a look at the code first. If
you have specific questions about it, ask here.
Before you make changes to the code, it would be useful if you would
describe
what you are planning on doing. You may be doing something useful to
other
parts of the community or even the whole community. If so, we can provide
feedback on what may be the best way to implement the changes you are
making
so that they can be most easily incorporated into the official codebase.
Thanks,
Josh

Hi,
Do you know where is the code VCL decides which computer will be used for
reservation, and how this decision is being made? I am still trying to
optimize the workload for now.

Xianqing,
The scheduler doesn't provide a way to do this right now. We will be
doing a
major overhaul to VM management in the 2.4 release which should provide
what
you are asking.

To whom it may concern:
Currently I am running ESX 3i servers on 7 blades. My VCL has 50
virtual
machines can be allocated. My question is that how to balance the
workload
on different blades? For instance, 7 virtual machines have been
reserved, in order to get best performance, how to allocate each
virtual
machine to different blades?
Thanks,
Xianqing
