Hi all, So I was doing some experiments to evaluate RTDS scheduler schedubility of real time tasks using 1vm with period of 10000 and budget of 10000. The experiment results turn out as expected(perform better than xen-credit).
But when I tried to perform similar experiments with 2 vms (both with now period of 10000 and budget of 5000). The schedubility of real time tasks turn out really bad. Even if I have one vm idling and the other vm running the real time tasks, the schedubility of that vm is still really poor(worse than xen-credit). Am I missing some configuration I should have set for 2vm cases? Thank you my setup is the following: Using Xen 4.5.0. 2vm sharing core 0-7, with RTDS scheduler, both has period of 10000 and budget of 5000 Dom0 using one core from CPU 8-15, with RTDS scheduler, period of 10000 and budget of 10000 The experiment I am doing is running real time tasks with different total utilization rate and measure the task success rate in the vm. Please let me know if you need any more information. Thank you! Victor
