Hi all,
I'm reading Remus part of Xen 4.x code and now I can find the entry code of Primary host, which is located in tools/remus directory. But I cannot find the entry code of backup host. Which codes will the backup host execute when the primary code send header of a VM? I can only find some codes are executed in tools/libxc/xc_domain_restore.c, which restores the backup VM as soon as the Primary VM stops. When the backup host synchronizing the state of primary VM (including machine state, memory state and disk state), which part of code will be execute?
