[Libguestfs] [PATCH v3 0/11] tests/qemu: Add program for tracing and analyzing boot times.
Lots of changes since v2, too much to remember or summarize. Please ignore patch 11/11, it's just for my testing. Rich.

[Libguestfs] [PATCH v3 03/11] appliance: Don't run hwclock command.
This command alone took 0.3 seconds which is about 10% of the current
launch time. It appears to be unnecessary.
This reverts commit 508f1ee87e816bf6b6fc8e629ccbb2d61a971169.

[Libguestfs] [PATCH v3 04/11] launch: direct: Remove dead code promising we were going to use virtio-console.
We're never going to use virtio-console since, although it is faster,
it's not available during early boot, and that is more important for
debugging.

[Libguestfs] [PATCH v3 05/11] conn: Pretend to be a serial terminal, so sgabios doesn't hang.
This tedious workaround avoids a 0.26 second pause when using sgabios
(the Serial Graphics Adapter). It's basically a workaround for buggy
code in sgabios, but much easier than fixing the assembler.

[Libguestfs] [PATCH v3 07/11] launch: direct: Don't run qemu -version.
Dr. David Gilbert pointed out to me that the first line of the
qemu -help output includes the qemu version, so we don't need
to run qemu -version at all.
This saves about 0.04s on the launch time when using the direct
backend.

[Libguestfs] [PATCH v3 09/11] launch: Remove guestfs_int_print_timestamped_message function.
This function was kind of like debug(), except that it didn't check
the g->verbose flag and it only worked in the library (it would crash
if used after fork).
It also wasn't very useful. The sort of boot analysis done by
tests/qemu/boot-analysis.c means that timestamping (some) messages is
even less interesting than before.
Remove it and replace calls with debug() instead.
