[Libguestfs] [PATCH v2 0/7] tests/qemu: Add program for tracing and analyzing boot times.

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 (it contains a useless ¼s sleep waiting for a keypress ... ffs!), and the other ⅔rds is something else in SeaBIOS. Simply removing SGABIOS improves boot times to below 2s, but at a cost that we cannot see any messages from SeaBIOS so further measurement and therefore improvement becomes impossible. I'm going to try to fix SeaBIOS/SGABIOS first. See also: http://thread.gmane.org/gmane.comp.emulators.qemu/402196 Rich.
