Stefan Hajnoczi	2d82148859	nbd: support large NBD requests ... The Linux nbd driver recently increased the maximum supported request size up to 32 MB: commit 078be02b80359a541928c899c2631f39628f56df Author: Michal Belczyk <belczyk@bsd.krakow.pl> Date: Tue Apr 30 15:28:28 2013 -0700 nbd: increase default and max request sizes Raise the default max request size for nbd to 128KB (from 127KB) to get it 4KB aligned. This patch also allows the max request size to be increased (via /sys/block/nbd<x>/queue/max_sectors_kb) to 32MB. QEMU's 1 MB buffers are too small to handle these requests. This patch allocates data buffers dynamically and allows up to 32 MB per request.

Kevin Wolf	f17c90bed1	nbd: Keep hostname and port separate ... The NBD block supports an URL syntax, for which a URL parser returns separate hostname and port fields. It also supports the traditional qemu syntax encoded in a filename. Until now, after parsing the URL to get each piece of information, a new string is built to be fed to socket functions. Instead of building a string in the URL case that is immediately parsed again, parse the string in both cases and use the QemuOpts interface to qemu-sockets.c.
