Hi to all,
correct me if I am wrong but isn't it the following the logical
execution chain of a generic system call performed
in a Kvm guest?
Guest userspace application -> Guest kernel -> Host kernel (kvm) ->
Host userspace (Quemu) -> Host kernel ->
-> Host userspace (Quemu) -> Guest kernel -> Guest userspace application
No. The actual path is
guest userspace -> guest kernel -> guest userspace
The guest kernel might access emulated hardware, but usually it does not.
Is there any detailed documentation on how this happens inside qemu-kvm?
No.

Do not meddle in the internals of kernels, for they are subtle and quick to
panic.
