[libvirt] [PATCH] qemu_driver: pass path of compress prog directly
by Chen Hanxiao
From: Chen Hanxiao <chenhanxiao(a)gmail.com>
We check compress prog in qemuCompressProgramAvailable,
then check it again in virExec.
This path will pass compress prog's path directly.

[libvirt] [PATCH 0/2] Report block jobs more wisely
by Michal Privoznik
There's been a discussion recently (even here on the list [1])
that Nova is sometimes unable to fetch block job stats properly.
Basically, we may report job.cur == job.end == 0 in some cases
tricking Nova into thinking job is done when in fact it hasn't
even started yet.

[libvirt] [PATCH v2 0/3] Introduce aliases for virt-admin's srv-* commands
by Erik Skultety
the original version:
https://www.redhat.com/archives/libvir-list/2016-September/msg00312.html
since v1:
- tweaked the virsh-self-test so that it also checks the aliased commands
instead of skipping them (since there was a good reason for that before the
changes this series introduces)
- patches 2-3 remained untouched
Erik Skultety (3):
virt-admin: Tweak command parsing logic so that aliases point to new
commands
virt-admin: Add some command aliases to provide syntax sugar over ugly
commands
virt-admin: Replace the (now) aliases with new command names in the
man page

Re: [libvirt] AC_HEADER_MAJOR vs. glibc 2.25(-to-be)
by Eric Blake
[adding libvirt list, as this is what sparked my investigations so far
today]
On 09/13/2016 04:36 PM, Eric Blake wrote:

Okay, I have confirmed that this prime-the-cache idea DOES work, using
libvirt.git commit 419bc8cf (one commit prior to d53fa838 which
installed a hack into libvirt to force the use of -Werror for the
duration of AC_HEADER_MAJOR [1]). By itself, './configure' succeeds but
leaves MAJOR_IN_SYSMACROS undefined, which results in a build failure
later in libvirt; but when run as './configure
ac_cv_header_sys_types_h_makedev=no', MAJOR_IN_SYSMACROS gets defined
and the build succeeds.
I want to remove the libvirt hack (not all compilers understand -Werror,
even if libvirt is only ever built by gcc or clang), and my experiment
was enough to prove that:
1. distros that provide a config.site file can use this file to avoid
the problem, even for packages that have not yet rebuilt with a
new-enough autoconf to fix the issue
2. autoconf and gnulib should indeed be fixed to probe for
<sys/sysmacros.h> _prior_ to probing for whether makedev() exists in
<sys/type.h>, rather than the 2.69 logic of only checking for
<sys/sysmacros.h> if makedev() was not found earlier.
Of course, the libvirt hack should not be reverted until autoconf and
gnulib have the final solution in place.

The current autoconf code assumes that if <sys/sysmacros.h> exists, then
it defines major()/minor()/makedev(); I think that assumption is still
safe. Where autoconf was wrong was that it was not even probing for the
existence of <sys/sysmacros.h> if it found that <sys/types.h> was enough
to pollute the namespace with the three macros.

[libvirt] [PATCH 0/4] Introduce aliases for virt-admin's srv-* commands
by Erik Skultety
So, as suggested by Martin in [1], this series tweaks the command alias
handling logic, so that when creating alias, it is not necessary to duplicate
the original command's structure, thus creating a bit more noise. Instead,
the new format for an alias structure hints very clearly that it's just an
alias for a different command, while linking the alias with the original
command's data by using new element '.alias'.
