2. Scheduling. Here, there is the mature KVM and Xen code to find inspiration in. Xen being the Type 1 hypervisor should likely be closer to MSHV in my understanding.Yes and no. When a hypervisor-based scheduler (either classic or core) is used, the scheduling model is the same as Xen. In this model, the hypervisor makes the scheduling decisions. There is a second scheduler model. In that model, the hypervisor delegates scheduling to the Linux kernel. The Linux scheduler makes the scheduling decisions. It is similar to KVM. We support both. Which model to use largely depends on the workload and the desired behaviors of the system. This is purely informational in case people wonder why the run vp function branches off to two different code paths.
Thanks, now I understand that better :) [...]
