[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.

[Libguestfs] [PATCH v2 1/7] appliance: Print location of udevd.
This is useful for debugging (but we can't print it unconditionally
since we cannot run grep etc yet). It also allows us to identify
when udevd is invoked so we can time it for boot analysis.

[Libguestfs] [PATCH v2 4/7] 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 v2 5/7] 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.

+ * The way it works is roughly like this:
+ *
+ * We create a libguestfs handle and register callback handlers so we
+ * can see appliance messages, trace events and so on.
+ *
+ * We then launch the handle and shut it down as quickly as possible.
+ *
+ * While the handle is running, events (seen by the callback handlers)
+ * are written verbatim into an in-memory buffer, with timestamps.
+ *
+ * Afterwards we analyze the result using regular expressions to try
+ * to identify a "timeline" for the handle (eg. at what time did the
+ * BIOS hand control to the kernel).
+ *
+ * The whole process is repeated across a few runs, and the final
+ * timeline (including statistical analysis of the variation between
+ * runs) gets printed.
+ *
+ * The program is very sensitive to the specific messages printed by
+ * BIOS/kernel/supermin/userspace, so it won't work on non-x86, and it
+ * will require periodic adjustment of the regular expressions in
+ * order to keep things up to date.

[Libguestfs] [PATCH v2 7/7] 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.

That could be because of: https://bugzilla.redhat.com/show_bug.cgi?id=1319483 Interestingly your total time is at least double mine. Either your hardware is slower or there's something else going on.> Thought to try booting a Xen PV domain for comparison, but AFAICT > libguestfs doesn't support LIBGUESTFS_BACKEND=libvirt:xen:///No, this isn't really going to work.

Re: [Libguestfs] [PATCH v2 0/7] tests/qemu: Add program for tracing and analyzing boot times.
I gave this series a spin, along a custom QEMU, and `supermin` from Git,
for my `libguestfs-test-tool` itself fails with:
"Could not open option rom 'linuxboot_dma.bin': No such file or
directory"
How I went about:
(1) Build QEMU with
https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg05891.html
-- Add optionrom compatible with fw_cfg DMA version
Build QEMU with the above patch:
$ w3m https://patchwork.ozlabs.org/patch/575578/mbox \
> add-optionrom-compatible-with-fw_cfg-DMA-version.patch
$ git am -3 \
~/add-optionrom-compatible-with-fw_cfg-DMA-version.patch
# sudo dnf builddep qemu -y
$ ~/src/qemu/configure --target-list=x86_64-softmmu
$ make -j4
(2) Build 'supermin' from Git
(3) Build 'libguestfs' from Rich's fork
https://github.com/rwmjones/libguestfs/commits/master/
Configure libguestfs (from Rich's fork) with `supermin` built from
Git in step (2):
$ SUPERMIN=~/src/supermin/src/supermin ./configure
$ ./bootstrap && ./autogen.sh && make
Compile libguestfs:
$ ./autogen.sh
$ make -j22
(4) Use the QEMU built in step (1), build and run the 'boot-analysis'
program from libguestfs test suite:
$ export
LIBGUESTFS_HV=$HOME/build/qemu-build/x86_64-softmmu/qemu-system-x86_64
$ make -C tests/qemu boot-analysis
$ ./run tests/qemu/boot-analysis -v
One and a half minute passes, nothing is printed on the screen. . .
Okay, let's try 'libguestfs-test-tool' (untruncated output
attached), it
fails with:
