Subject: [PATCH] qxl: Add rom_size compat property, fix migration from 1.2
|
|
|
|
Commit 038c1879a00153b14bce113315b693e8c2944fa9 changed the qxl rom
|
|
size to 8192, which fixes incoming migration from qemu 1.0. However
|
|
from qemu 1.2 and 1.3 had rom size 16384, so incoming migration
|
|
from those versions is now broken.
|
|
|
|
Add a rom_size compat property. 1.2 and 1.3 get 16384, everything
|
|
else is 8192.
|
|
|
|
This isn't actually fool proof, since rom_size can be dependent on
|
|
the version of spice qemu is built against:
|
|
|
|
https://lists.gnu.org/archive/html/qemu-devel/2013-02/msg03154.html
|
|
|
|
However these sizes match what native Fedora packages get, so it's
|
|
good enough for now.
