Greetings!
I am new to kvm Libvirt 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 libvirt 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
VIR_NODE_MEMORY_STATS and kvm_get_dirty_log(struct kvm *kvm, struct
kvm_dirty_log *log, int *is_dirty),
I do not know if these are the ones and if yes how I can use them.
Thank you very much
