+From: Glauber Costa <glommer@redhat.com>
+Subject: [PATCH] align vga rom to 4k boundary.
+
+Instead of aligning to 2k boundary, as required by the bios,
+align to 4k boundary, as required by kvm memory functions. Without
+this patch, starting kvm with -vga std option fails with:
+
+create_userspace_phys_mem: Invalid argument
+kvm_cpu_register_physical_memory: failed
+
+as described by: https://bugzilla.redhat.com/494376
+
+It does not fail with cirrus vga, because it is naturally aligned.
+This problem does not seem to affect upstream qemu.
