Read the content of /proc/cmdline using bash features, and use its [[ ... ]] expression to find texts in a variable.

Using the quiet option (when not in verbose mode) improves boot speeds by rather a lot, by avoiding sending messages over the slow emulated UART. Rich.

Lots of changes since v2, too much to remember or summarize. Please ignore patch 11/11, it's just for my testing. Rich.

v1 was here: https://www.redhat.com/archives/libguestfs/2016-March/thread.html#00157 Not running the 'hwclock' command reduces boot times considerably. However I'm not sure if it is safe. See the question I posted on qemu-devel: http://thread.gmane.org/gmane.comp.emulators.qemu/402194 At the moment, about 50% of the time is consumed by SeaBIOS. Of this, about ⅓rd is SGABIOS
