The vram attribute was introduced to set the video memory but it is usable only for few hypervisors excluding QEMU/KVM and the old XEN driver. Only in case of QEMU the vram was used for QXL. This patch updates the documentation to reflect current code in libvirt and also changes the cases when we will set the default vram attribute. It also fixes existing strange default value for VGA devices 9MB to 16MB because the video ram should be rounded to power of two. The change of default value could affect migrations but I found out that QEMU always round the video ram to power of two internally so it's safe to change the default value to the next closest power of two and also silently correct every domain XML definition. And it's also safe because we don't pass the value to QEMU. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1076098 Signed-off-by: Pavel Hrdina <phrdina@redhat.com>
