[libvirt] [PATCH] Fix handling of Xen(ner) detection

Latest upstream QEMU can be built with Xen support, which introduces a -xen-domid argument. This was mistakenly detected as -domid due to old Xenner support. Adapt to cope with both syntax. Also only set domid if the virt type is xen, or the guest type is xen * src/qemu_conf.c, src/qemu_conf.h: Detect new -xen-domid flag in preference to -domid. * tests/qemuxml2argvdata/qemuxml2argv-bootloader.args, tests/qemuxml2argvdata/qemuxml2argv-input-xen.args: Add missing -domid param * tests/qemuxml2argvdata/qemuxml2argv-misc-uuid.args: Remove bogus -boot param. * tests/qemuxml2argvdata/qemuxml2argv-misc-uuid.xml: Fix domain type to be xen * tests/qemuxml2argvtest.c: Add missing QEMUD_CMD_FLAG_DOMID params --- src/qemu_conf.c | 31 +++++++++++++++---- src/qemu_conf.h | 1 + .../qemuxml2argvdata/qemuxml2argv-bootloader.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-input-xen.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-misc-uuid.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-misc-uuid.xml | 3 +- tests/qemuxml2argvtest.c | 4 +- 7 files changed, 31 insertions(+), 14 deletions(-) diff --git a/src/qemu_conf.c b/src/qemu_conf.c index 22f5edd..e8414c3 100644 --- a/src/qemu_conf.c +++ b/src/qemu_conf.c @@ -769,7 +769,9 @@ static unsigned int qemudComputeCmdFlags(const char *help, flags |= QEMUD_CMD_FLAG_NAME;
