[Xen-API] Credit scheduler tuning knobs

[Dimosthenis Pediaditakis <dimosthenes@xxxxxxxxx>]

Hi everyone,Â

In short, I was wondering if XEN-API supports a configuraiton option similar to the cpu-pools of the XL toolchain:

http://wiki.xen.org/wiki/Cpupools_Howto

I am mainly interested in setting via XEN-API (xe) Âthe following parameters of the credit scheduler:

Â- time slice

Â- rate limit

After quick look in the sources of XL, it seems that ends up issuing the following hypercall:

XEN_DOMCTL_SCHEDOP_putinfo

see here: http://goo.gl/KQjlTR

Is there a way to send hypervisor the same hypercall via XEN-API ?

I would like to avoid hard-coding the time-slice and ratelimit value in the sources of Xen.

Thank you,

Dimos
