[Qemu-devel] [PATCH 06/20] Improve qemu-nbd performance by 4400 %

From: Laurent Vivier This patch allows to reduce the boot time from an NBD server from 225 seconds to 5 seconds (time between the "boot cd:0" and the kernel init) for the following command lines: ./qemu-nbd -t ../ISO/debian-500-powerpc-netinst.iso and ./ppc-softmmu/qemu-system-ppc -cdrom nbd:loc

[Qemu-devel] [PATCH 05/20] raw-posix: handle > 512 byte alignment correctly

From: Christoph Hellwig Replace the hardcoded handling of 512 byte alignment with bs->buffer_alignment to handle larger sector size devices correctly. Note that we can not rely on it to be initialize in bdrv_open, so deal with the worst case there. Signed-off-by: Christoph Hellwig Signed-off-b
