Hi all, There are some vmfork features provided by Xen based on shadow page table few years ago. I am wondering whether KVM provides the similar feature on the same host. By triggering vmfork, we can get a child VM which CPU and I/O status is the same as the parent, and the memory is CoW shared with parent VM.
