           Summary: Xend should wait for qemu-dm to initialize before
                    succeeding on domain creation
           Product: Xen
           Version: unstable
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: aliguori@xxxxxxxxxx


qemu-dm does a bunch of argument sanity checking in vl.c to see if the device
files exist and such.  Instead of just fork/exec()'ing qemu-dm, we ought to
treat it like a daemon and use a trick like polling for stdout closing to let
qemu-dm get beyond the argument validation before actually returning on domain
creation.
