Hi Dario, Thanks for the reply! My goal for the experiment is to show that xen rtds scheduler is better than credit scheduler when it comes to real time tasks. so my set up is: for xen-credit : 2vms sharing 8 cores (cpu 0-7) using credit scheduler(both with weight of 800 and capacity of 400) for xen-rtds: 2 vms sharing 8 cores (cpu0-7) using RTDS (both with period of 10000 and budget of 5000) in both setup, dom0 is using 1 core from cpu 8-15 VM2 will run tasks that has utilization of 4 cores. VM1 will run tasks that has utilization from 1 to 4, and I will record VM1's schedulbility. I am hoping to see that the VM1 using xen-rtds will perform better than the VM1 using xen-credit, but what I am seeing is the opposite. Thank you!
