Since the cirrus vga memory size isn't configurable, we can ignore any 'vram' attribute when parsing a domain definition. However, when no value is specified, it ends up getting set to a default value of 16MB. This 16MB value is not used anywhere (for example, it is not passed as an argument to qemu), but is displayed in the XML definition. So by changing this default value to 0, it will also be omitted from the XML definition of the domain. Fixes: rhbz#1447831 Signed-off-by: Jonathon Jongsma <jjongsma@xxxxxxxxxx> --- This is an attempt to apply the fix suggested by Gerd at https://bugzilla.redhat.com/show_bug.cgi?id=1447831#c2. I'm not totally confident that this is the right approach, since I'm relatively new to the code. Another approach might be to simply close the bug as NOTABUG since it doesn't seem that having this unused attribute in the domain definition has any significant drawbacks. src/conf/domain_conf.c | 2 +- src/qemu/qemu_domain.c | 3 +++ 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index c69d382d70..d06e094b11 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -15154,7 +15154,6 @@ virDomainVideoDefaultRAM(const virDomainDef *def, { switch (type) { case VIR_DOMAIN_VIDEO_TYPE_VGA: - case VIR_DOMAIN_VIDEO_TYPE_CIRRUS: case VIR_DOMAIN_VIDEO_TYPE_VMVGA: if (def->virtType == VIR_DOMAIN_VIRT_VBOX) return 8 * 1024; @@ -15172,6 +15171,7 @@ virDomainVideoDefaultRAM(const virDomainDef *def, /* QEMU use 64M as the minimal video memory for qxl device */ return 64 * 1024; + case VIR_DOMAIN_VIDEO_TYPE_CIRRUS: case VIR_DOMAIN_VIDEO_TYPE_DEFAULT: case VIR_DOMAIN_VIDEO_TYPE_VBOX: case VIR_DOMAIN_VIDEO_TYPE_PARALLELS: diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index e5c6ef3fda..7f0baf57ac 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -6835,6 +6835,9 @@ qemuDomainDeviceVideoDefPostParse(virDomainVideoDefPtr video, if (video->type == VIR_DOMAIN_VIDEO_TYPE_QXL && !video->vgamem) { video->vgamem = QEMU_QXL_VGAMEM_DEFAULT; + } else if (video->type == VIR_DOMAIN_VIDEO_TYPE_CIRRUS) { + /* cirrus vram is not configurable.
