runsc/boot/loader.go

There are two kernel structs, kernel.Kernel and ring0.Kernel. kernel.Kernel contains most of kernel data structures while ring0.kernel only contains PageTables *pagetables.PageTables and globalIDT idt64. As shown in the following figure, loader.go will create a VM and setup kernel.Kernel, while the KVM will setup ring0.Kernel. Figure source is on plantuml.
