Just shutdown the blockdevices and be done with= it? Anthony, it looks like 5d6c599fe1 ("migration, xen: Fix block image lock is= sue on live migration") went too far. Why does stopping the disks at the ve= ry end of the save/migrate process depend on "live"? During a migration the= disks have to be released either way. During "xl save" the domU may contin= ue to run, if '-c' was specified.=20 It seems the 'live' parameter for xen-save-devices-state is not needed.
