- when looking for an error message in qemu log, accept more patterns, because QEMU executable may be named slightly differently than literally "qemu" - disable QEMU's terminal features when STDOUT is not a terminal - allow mounting the ISO via sudo, because the default method (udisks) needs additional PolicyKit configuration Story: 2007858 Task: 40441 Change-Id: I19ec7e55aaa80b6ed98162b65e41ce1a63f6da40
