I added the cirrus video memory setting in libxl time ago (using -global
vga.vram_size_mb), testing it with qemu 1.3 and also on qemu 1.6 when I
changed from -vga to -device if I remember good.
Has been changed in recent versions or something was not right even
though it seemed right to me?
There are multiple graphics cards to choose from. When using -vga std or
-device vga, then -global vga.foo=bar gets used; if -vga cirrus or
-device cirrus-vga then it needs to be -global cirrus-vga.foo=bar and
any -global vga.foo=bar gets ignored - unless you manage to add it as
secondary (PCI) graphics card.
