This patch set re-implements migration with storage for enough new qemu.
How does this series interact with Li Guang's efforts to add offline migration? In particular,
1) src -> dest: (QEMU_MIGRATION_PHASE_BEGIN3 -> QEMU_MIGRATION_PHASE_PREPARE) <nbd> <disk src='/var/lib/libvirt/images/f17.img' size='17179869184'/> </nbd>
Both sets of patches need to pass size information across in the cookies; so is tying it to <nbd> appropriate, or should we be rethinking this XML to be shared between both patches?
actually, I think 'src' is unnecessary, for 'def->disks[i]->src' shared between src & dst, size and 'src' paired one by one, we will not make a mistake to match them. -- regards! li guang linux kernel team at FNST, china thinking with brain but heart living with heart but brain
