Re: [libvirt] [PATCH] qemu: Detect VGA_QXL capability correctly

Since 4c993d8a we failed to set this important capability, which allows starting a domain with QXL video card. We set DEVICE_QXL capability bit instead, which is not necessary wrong. Anyway, if qemu supports the new '-device qxl' it supports older '-vga qxl' as well. The latter is used for the primary (the first) qxl video card, the former for other video cards. --- Other approach is to set QEMU_CAPS_VGA_QXL unconditionally as supported by all qemu-1.2+ in qemuCapsInitQMPBasic(). But I think this one is slightly nicer. src/qemu/qemu_capabilities.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index f49a31c..e16bc70 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -2018,6 +2018,9 @@ qemuCapsProbeQMPObjects(qemuCapsPtr caps, /* Prefer -chardev spicevmc (detected earlier) over -device spicevmc */ if (qemuCapsGet(caps, QEMU_CAPS_CHARDEV_SPICEVMC)) qemuCapsClear(caps, QEMU_CAPS_DEVICE_SPICEVMC); + /* If qemu supports newer -device qxl it supports -vga qxl as well */ + if (qemuCapsGet(caps, QEMU_CAPS_DEVICE_QXL)) + qemuCapsSet(caps, QEMU_CAPS_VGA_QXL); return 0; } -- 1.8.0.2
