Subject: Re: The RAM MEM inside KVM instance is not the same as it was set
Hi, Cristian,
When ACS is deploying a VM, it defines a minimum memory|CPU to the VM, based on
a calculation through the overprovisioning (defined mem|cpu speed /
overprovisioning factor); Therefore, it will define a range of memory|CPU, even
if it does not use scalable (dynamic) service offerings.
For now, the option to avoid this behavior is to keep memory overprovisioning
as "1", as Wei suggested. However, in version 4.16.0, there'll be two new
global settings
("vm.min.memory.equals.memory.divided.by.mem.overprovisioning.factor" and
"vm.min.cpu.speed.equals.cpu.speed.divided.by.cpu.overprovisioning.factor") to
avoid it.
This is the PR which introduced it:
https://github.com/apache/cloudstack/pull/4722
Best regards,
Daniel
