The save process was relying on use of the shell >> append operator to ensure the save data was placed after the libvirt header + XML. This doesn't work for block devices though. Replace this code with use of 'dd' and its 'seek' parameter. This means that we need to pad the header + XML out to a multiple of dd block size (in this case we choose 512). The qemuMonitorMigateToCommand() monitor API is used for both save/coredump, and migration via UNIX socket. We can't simply switch this to use 'dd' since this causes problems with the migration usage. Thus, create a dedicated qemuMonitorMigateToFile which can accept an filename + offset, and remove the filename from the current qemuMonitorMigateToCommand() API * src/qemu/qemu_driver.c: Switch to qemuMonitorMigateToFile for save and core dump * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h, src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Create a new qemuMonitorMigateToFile, separate from the existing qemuMonitorMigateToCommand to allow handling file offsets
