https://bugzilla.redhat.com/show_bug.cgi?id=620363 When using -incoming stdio or -incoming exec:, qemu keeps the stdin fd open long after the migration is complete. Not to mention that exec:cat is horribly inefficient, by doubling the I/O and going through a popen interface in qemu. The new -incoming fd: of qemu 0.12.0 closes the fd after using it, and allows us to bypass an intermediary cat process for less I/O. * src/qemu/qemu_command.h (qemuBuildCommandLine): Add parameter. * src/qemu/qemu_command.c (qemuBuildCommandLine): Support migration via fd: when possible. Consolidate migration handling into one spot, now that it is more complex. * src/qemu/qemu_driver.c (qemudStartVMDaemon): Update caller. * tests/qemuxml2argvtest.c (mymain): Likewise. * tests/qemuxml2argvdata/qemuxml2argv-restore-v2-fd.args: New file. * tests/qemuxml2argvdata/qemuxml2argv-restore-v2-fd.xml: Likewise.
