Hi, for a uni project I'm trying to write a userspace for KVM that can run ELF binaries without a full blown OS in the guest. The idea is to handle any syscalls made by the binary running inside the guest in the userspace of the host. In the simplest case you could forward them to the host Linux kernel. In any case, I've gotten pretty far, setting up IDTs, the VCPU, Page Tables and whatnot, but right now I'm stuck. I setup my syscall handler to do a VMCALL, which according to the Intel manual is supposed to return control to the host. However this seems to be handled by KVM without an exit into userspace? If this is correct, is there any way to make a call to the host VMM, that will be transfered to userspace by KVM?
