2016-02-09qemu-nbd: Fix unintended texi verbatim formattingSitsofe Wheeler
Indented lines in the texi meant the perlpod produced interpreted the paragraph as being verbatim (thus formatting codes were not interpreted). Fix this by un-indenting problem lines.

2013-12-04qemu-nbd: support internal snapshot exportWenchao Xia

2013-04-15Add -f FMT / --format FMT arg to qemu-nbdDaniel P. Berrange
Currently the qemu-nbd program will auto-detect the format of any disk it is given. This behaviour is known to be insecure. For example, if qemu-nbd initially exposes a 'raw' file to an unprivileged app, and that app runs 'qemu-img create -f qcow2 -o backing_file=/etc/shadow /dev/nbd0' then the next time the app is started, the qemu-nbd will now detect it as a 'qcow2' file and expose /etc/shadow to the unprivileged app. The only way to avoid this is to explicitly tell qemu-nbd what disk format to use on the command line, completely disabling auto-detection. This patch adds a '-f' / '--format' arg for this purpose, mirroring what is already available via qemu-img and qemu commands. qemu-nbd --format raw -p 9000 evil.img will now always use raw, regardless of what format 'evil.img' looks like it contains Signed-off-by: Daniel P.
