The reason why libvirt worked out before is that there is a typo for the caps flag bit QEMU_CAPS_VGA_QXL fixed in the above commit. And libvirt didn't set QEMU_CAPS_VGA_QXL on for qemu(>1.2) by using QMP mode to check for qemu capabilities. - { "qxl", QEMU_CAPS_VGA_QXL }, + { "qxl", QEMU_CAPS_DEVICE_QXL }, So Doug's patch probably could fix your problem <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> temporarily, but we need to think it through as Eric said.
