- Align VGA ROM to 4k boundary - fixes 'qemu-kvm -std vga' (#494376)
qemu-roms-more-room-fix-vga-align.patch:
--- NEW FILE qemu-roms-more-room-fix-vga-align.patch ---
From: Glauber Costa <glommer at 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.
