Hi,

is tunnelled migration with libvirt 0.9.0 and qemu-kvm 0.14.0 broken ?

all I get is an error "unknown migration protocol"

while looking at the code in src/qemu/qemu_migration.c

src/qemu/qemu_migration.c:

     /* Start the QEMU daemon, with the same command-line arguments plus
      * -incoming stdin (which qemu_command might convert to exec:cat or 
fd:n)
      */
     internalret = qemuProcessStart(dconn, driver, vm, "stdin", true, 
dataFD[1],
                                    NULL, VIR_VM_OP_MIGRATE_IN_START);



migrateFrom is set to "stdin" but in src/qemu/qemu_command.c
there is no such match which ends in the above error.

Regards,
Jason
