Variable speed CPUs
Hi,
I have build a small private cloud for an R&D project for one of my clients. I have 3 hosts each with 16gb memory and 8 cores (AMD) per host. I’m using Cloudstack 4.1 and hosts are Ubuntu 12.04 w/KVM. These CPUs can vary clock speeds based on bios settings which is enabled. The Cloudstack dashboard correctly estimates the CPU clock speed at its MAX of 3500 MHz. But, when I log onto the guests and run virt-top it says 1400MHz which I assume is its current throttled down clock speed. I am still setting things up and have not had the chance to put the hosts under enough load to see of it clocks up. My questions are: Does Cloudstack support viewable clocked CPUs in hosts? How does Cloudstack support variable clocked hosts from a real-time capacity load perspective and a usage perspective.
Thanks
Pete Johnson

Jithin, I have just tested this against my production setup running 4.1.1
on Ubuntu 12.04 w/ KVM, my mistake, the clockspeed of the service offering
does not get passed to KVM. However, if the clockspeed of the service
offering is higher than the host (3500Mhz in your case Pete), then the VM
will not boot.
Pete are correct in thinking that Cloudstack will assume 3.5Ghz regardless
of its actual clockspeed, this makes no difference as some processors do
this anyway with no effect to applications.
Thanks,
Marty

Hi Marty,
Not sure though, but I don't see the clock speed mentioned at the service
offering is set as a configuration parameter of the guest OS for kvm.
Rather the clock speed set for the service offering is used as a reference
of the resource utilization while allocating host for the instances
deployed using service offering.
Pete: Which is the model number of the AMD processor you are using?
>From KVM perspective,We can specify the number of vCPUs to be allocated to

"--cpuset=CPUSET
Set which physical cpus the guest can use. "CPUSET" is a comma
separated list of numbers, which can also be specified in ranges or cpus to
exclude. Example:
0,2,3,5 : Use processors 0,2,3 and 5
1-5,^3,8 : Use processors 1,2,4,5 and 8"

Hi Marty,
Not sure though, but I don't see the clock speed mentioned at the service
offering is set as a configuration parameter of the guest OS for kvm.
Rather the clock speed set for the service offering is used as a reference
of the resource utilization while allocating host for the instances
deployed using service offering.
Pete: Which is the model number of the AMD processor you are using?
>From KVM perspective,We can specify the number of vCPUs to be allocated to
guests, also it supports which physical CPU to use:
"--cpuset=CPUSET
Set which physical cpus the guest can use. "CPUSET" is a comma
separated list of numbers, which can also be specified in ranges or cpus to
exclude. Example:
0,2,3,5 : Use processors 0,2,3 and 5
1-5,^3,8 : Use processors 1,2,4,5 and 8"

So I ran the lshw -C CPU command. it says the capacity is 3500MHz and the
size is 1400MHz. Not sure what size means. But, per your comments and the
fact that I have a 2 - core 2GHz guest running on it implies its looking at
the capacity rather then size.
So you are saying that Cloudstack/KVM will assume it’s a 3500MHz processor
regardless of its actual clock speed in real-time?
