[PATCH v2 0/2] lib: qemu: Memoize qemu feature detection.
v1 -> v2:
- Rebase on top of Pino's version work.
Two patches went upstream, these are the two remaining patches.
Note the generation number is still inside the qemu.stat file. We
could put it in the filename, I have no particular preference.

[PATCH 0/5] Assorted patches to add virtio-scsi support.
These assorted patches end up with adding virtio-scsi support to
libguestfs.
It passes libguestfs-test-tool, but I haven't yet tried to run the
full set of tests.
In theory > 26 devices can be added, but it's likely that certain
parts of the daemon will break if you actually try this. This of
course needs to be fixed.
Thanks Paolo Bonzini for invaluable help.

[PATCH 0/4] lib: qemu: Memoize qemu feature detection.
Doing qemu feature detection in the direct backend takes ~100ms
because we need to run `qemu -help' and `qemu -devices ?', and each of
those interacts with glibc's very slow link loader.
Fixing the link loader is really hard. Instead memoize the
output of those two commands.
This patch series first separates all the code dealing with qemu into
a separate module (src/qemu.c) and

[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.

[PATCH libguestfs 0/4] Add a libvirt backend to libguestfs.
This preliminary patch series adds a libvirt backend to libguestfs.
It's for review only because although it launches the guest OK, there
are some missing features that need to be implemented.
The meat of the patch is in part 4/4.
To save you the trouble of interpreting libxml2 fragments, an example
of the generated XML and the corresponding qemu command line are
attached below. Note the

[PATCH 0/2] Don't use snapshot=on
QEMU upstream has broken snapshot=on ... again.
These two patches stop using it entirely. Instead we run
'qemu-img create' to create overlay disks as required.
Note that the libvirt and UML backends were already doing this: The
libvirt backend because <transient/> has never worked, and the UML
backend was running uml_mkcow because the UML-equivalent syntax of
snapshot=on was

[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
