Hi,

> - add file:// migration protocol (Uri Lublin)

commit 70d2a9dc3594446f3ad66b32abc94c08b74118d4

    kvm: qemu: migration: added file:// migration protocol
    
    Instead of writing into a file with fork+exec, just open the file and
    write the data. This solves a bug that sometimes not all the data was
    kept in the state-file.

I haven't tested it yet, but this sounds like the problems I've always
had with migration.  It seems this is just a new way to work around
it, rather than an actual fix for the bug though -- won't exec: still
have the same problem even when not writing to a file?  Was this
ever tracked down any further?  Or is there a known reason why 
"exec:dd" is expected to be broken?  I never had any luck finding it..
