[Qemu-devel] [PATCH] secondary-vga: unregister vram on unplug.

[remy . noel]

From: "Remy Noel" <address@hidden>

When removing a secondary-vga device and then adding it back (or adding
an other one), qemu aborts with:
    "RAMBlock "0000:00:02.0/vga.vram" already registered, abort!".

It is caused by the vram staying registered, preventing vga replugging.
