seem flags was forgotten at qemuDomainMigratePrepare3, so any preparation for offline migration will be impossible, isn't it? do you mean I should change MigratePrepare functions to add flags as a parameter?
Huh? qemuDomainMigratePrepare3 already has a flags argument (arg 8), and it is directly related to the flags argument that was originally passed to virDomainMigrate() in libvirt.c.
please check qemuMigrationPrepareDirect called in qemuDomainMigratePrepare3
qemuMigrationPrepareDirect is not a callback, and not a public API, so you are free to change its signature and add a flags parameter if that is necessary to get the information to the right places. The only signatures you can't change are in src/libvirt.c and in functions serving as callbacks registered through signatures in src/driver.h.
OK, will change. -- li guang lig.fnst@cn.fujitsu.com linux kernel team at FNST, china
