I tried to disable "default floppy" without use -nodefaults option that
disable other things.
I didn't found other parameters to do that in docs and code for now.
Can someone tell me if there is another way to disable default floppy only?
About stdvga, I found that memory is configurable from
docs/spec/standard-vga:
Framebuffer memory, 16 MB in size (by default).
Size is tunable via vga_mem_mb property.
vga_mem_mb seems wrong in doc, I didn't found it in the code with grep
so I tried to use -global vga.vram_size_mb, that (looking at code) seems
the correct one.
By default xen reserve 8 mb of videoram but stdvga default is 16 mb.
Tried out a domU with Xen, if the memory required from vga is more than
memory reserved by xen it should give an error (like qxl and cirrus),
but with stdvga I cannot get any error at all.
I know that in xen there are changes and/or bugfix (probably in
hvmloader) to have the emulated vgas full working with qemu upstream but
probably stdvga has something to fix and/or improve also on qemu part.
Can someone tell me if memory setting of stdvga is working?
Is correct to have no errors from xen even if it reserves only 8 mb by
default and this size is not setted on qemu with -global?
