virtual machines and the assignment of physical CPUs
Hi,
I found a problem with the virtual machines and the assignment of physical CPUs, in the case of vmware there are not many problems, this only allows one physical CPU to allocate to a virtual processor.
But there are other cases, such as IBM's System i equipment, which allow you to assign a percentage of a CPU or a set of cpus.
In these cases the assignment can also vary dynamically, ie, 100% cpu usage would not be always representing the same information.
The only way I can think of to deal with this problem is to analyze metrics such as number floating point operations that can perform virtual machine on that moment, but the problem is that for this calculation should I stress the cpu.
Another case would also be similar is if I have a virtual machine running on the Amazon cloud, and then I run it on local environment.
The cpu usage metrics would not be comparable and would make a
comparison stress.
Does anyone has had these kinds of problems?, Do you able to solve it differently?
In our case we could not do stress, that the equipment is productive and is providing service to users.
greetings.
