CPU assignment
-
Hi have a host with a bunch of cores. 18 cores times 2 CPUs. The assignment looks like that in the Stats:
CPU is: [https://www.intel.de/content/www/de/de/products/sku/192451/intel-xeon-gold-6254-processor-24-75m-cache-3-10-ghz/specifications.html](link url)
My question now is: Why is nothing assigned to "CPU14"?
I would have thought, that XCP NG / Xen is distributing the load over all availabel cores.Is there any way to optimize that?

Hi!
I'm not sure, how you could say CPU14 is not working?
-
That was quick
I try it with other words: Let's assume I have two VMs with 10 CPUs assignes each. Then I would expect that VM1 uses CPU 0 to CPU 9 and VM2 uses CPU 10 to CPU 19. But not both of them are using CPU 0 to CPU 9.
Is my assumption wrong?
And to answer your question: As there is no data for CPU 15 and above. And there are 9VMs on that host with in total much more than 15 CPUs ssigned.

It doesn't work like that. Xen will schedule the vCPUs to all available cores. Like a regular operating system scheduler.
The graph you are showing is just "broken" in a way we don't have more than 14 colors, rest is in grey. But all CPUs will be used and the load will be dynamically spread to all available cores.

Oh. That clarifies it. Just the colors
Thank you! -
You are welcome
Enjoy XCP-ng/XO!
