           Summary: external-migration-tool: missing domU name on step0
           Product: Xen
           Version: unstable
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: hbaumann@xxxxxxxx
                CC: hbaumann@xxxxxxxx


the external-migration-tool script does not get -domname from xend on step 0 of
(live) migration. on all other steps xend calls with it with domU name.

the following patch works for me.

Environment
xen 3.1.0
gentoo 2007.0
kernel 2.6.18-xen
