int(* features_changed) (int vid, uint64_t features) |
Features could be changed after the feature negotiation. For example, VHOST_F_LOG_ALL will be set/cleared at the start/end of live migration, respectively. This callback is used to inform the application on such change.
Definition at line 288 of file rte_vhost.h.
void(* guest_notified) (int vid) |
This callback gets called each time a guest gets notified about waiting packets. This is the interrupt handling through the eventfd_write(callfd), which can be used for counting these "slow" syscalls.
