Re: [libvirt] [PATCH] qemu: Error prompt if invalid dump image format specified

"getCompressionType" trys to throw error when invalid dump image format is specified, or the compression program for the specified image format is not available, but at the same time, it returns enum qemud_save_formats, as a result, upper function will think it was successful, and disgard to check the error, this fix makes changes so that it returns -1 on FAILURE, And to be consistent with "save", won't use "raw" as the default dump format anymore. * src/qemu/qemu_driver.c - rename "getCompressionType" to "getDumpType" - return -1 on FAILURE
