Greetings!I am new to kvm and are writing a python script to get the number of pre-copy cycles during a remote vm migration given memory size M of a VM in MB, the page dirty rate R of a vm in MB/s. My question is on how to get the page dirty rate. Does kvm provide a dirty page log facility that provides user space with a bitmap of modified pages since the last call? And if yes, please kindly direct me on how to get started. I have searched and come across things like
int kvm_get_dirty_log(struct kvm *kvm, struct kvm_dirty_log *log int *is_dirty) I do not know if this is what I should use and if so how I could go about to implement it.
