Dear all, I wonder whether there is an easy way to configure how many cores nova-compute is supposed to use (or alternatively refrain from using) for provisioning of instances on a certain host, out of the total number of cores on that host? E.g., if I know that there are other things running on the host, and I want to dedicate some of the CPU capacity to them (such as OpenStack services themselves). I am thinking of KVM right now, but the general approach is probably platform-independent. Would appreciate your insights.
Thanks, Alex P.S. trivial solution is to dedicate entire host(s) to those other "things", and assume that nova-compute is running on hosts used *only* to run VMs (and that nova-compute itself does not need much CPU cycles). but I am looking for a more fine-grained approach. ==================================================================================================== Alex Glikson Manager, Cloud Operating System Technologies, IBM Haifa Research Lab http://w3.haifa.ibm.com/dept/stt/cloud_sys.html | https://www.research.ibm.com/haifa/dept/stt/cloud_sys.shtml Email: glik...@il.ibm.com | Phone: +972-4-8281085 | Mobile: +972-54-6466667 | Fax: +972-4-8296112
