[libvirt] [libvirt-php] About the inconsistency in libvirt-php
by Lyre
Hi all:
I noticed that there's some inconsistent behaviors in libvirt-php, and
wondering what's the best way to handle them.
In libvirt-php:
libvirt_list_domains() returns an array of all domain resource;
libvirt_list_active_domains() returns an array of running domain ids;
libvirt_list_defined_domains() returns an array of defined domain names.
and
libvirt_list_storagepools() returns an array of actived storagepool names.
In my opinion, returning an array of names would be better when listing all
kinds of objects.
And the naming convenances, let's take domains as an example.
libvirt-php provied
libvirt_list_domains() for all domains, which has no corresponding function
in libvirt.
libvirt_list_active_domains() for running domains, corresponding to
virConnectListDomains() in libvirt.
libvirt_list_defined_domains() for defined domains, corresponding to
virConnectListDefinedDomains() in libvirt.
I believe it is fine. However, for defined objects, sometimes it used term
"defined" (libvirt_list_defined_domains),
and sometimes use term "inactive" (libvirt_get_inactive_domain_count) in
contrast to "active". Which would be better?

[libvirt] hello, Would I request some support about libvirt API?
by Saint yeyo
Hello, honorific developers,
I'm a rookie came here to study something about libvirt, I find it a
little bit difficult for me to use the API, there is absence of
explanation of specific functions and examples. May I ask some kind of
you who provide some docs about that for me, I'll very appreciate for
you.
Thank you!
Best regard!

[libvirt] [libvirt-php 0/1] Added many apis for storagepool
by Lyre
Hi all:
This patch added the followings for storagepool:
libvirt_storagepool_get_uuid_string
libvirt_storagepool_get_name
libvirt_storagepool_lookup_by_uuid_string
libvirt_storagepool_get_xml_desc
libvirt_storagepool_define_xml
libvirt_storagepool_undefine
libvirt_storagepool_create
libvirt_storagepool_destroy
libvirt_storagepool_is_active
libvirt_storagepool_get_volume_count
libvirt_storagepool_refresh
libvirt_storagepool_set_autostart
libvirt_storagepool_get_autostart
These functions were taken from my own branch of original php-libvirt,
with some modification, and litte tests.
I've put the function prototype in git log, but it seems not a good idea.
Maybe I should provie the documents as well.
In my original branch, I've extended php-libvirt a lot with their own documents.
But I'm not able to simply merge it into libvirt-php: there're too many functions
, some designs are really problematical, libvirt-php have indent the source.
The documents may be not welly written, some statment don't looks like native
English, since I'm not English speaker.
I'm tring to find a way to move the source to into libvirt-php,
currently it was copy & paste with some adjustment.

[libvirt] [PATCH] storage: make debug log more useful
by Osier Yang
"__func__" should be replaced with "__FUNCTION__" instead for
better portability, however, VIR_DEBUG already prints the function
name, so it's useless, replace it with more useful log.

[libvirt] [RFC PATCH 0/2] audit cgroup ACL actions in qemu
by Eric Blake
I'm following up on danpb's patches to add initial audit support to
qemu actions (see around commit 8dc136b in Oct 2010). Another useful
thing to audit is all changes to the device ACL whitelist via the
cgroup device controller - namely, any time that the qemu cgroup is
altered to allow or deny access to a (set of) devices.
I saw an alternate suggestion for collecting the needed audit
information by using an inotify script outside of libvirt that
monitors changes to the cgroup file system corresponding to each qemu
instance; however, this had the drawback that it can only monitor that
a change is being attempted, but not the actual change being made. It
is necessary to use libvirt to provide the audit information, in order
to have a rich enough set of information to make the audit worthwhile.
I believe this patch series catches all instances where libvirt
modifies the whitelist for a qemu instance, but I didn't do anything
for when libvirt first creates a separate cgroup device whitelist as
part of starting a new guest. Also, I'm not sure if the amount of
information passed to the audit is adequate, or if it needs tweaking.
Also, libvirt blindly passes a long list of paths through the
low-level util/cgroup.c functions, including non-devices where it
ignores the EINVAL failure later. But this could pollute the audit
log with entries corresponding to cases where altering the actual
cgroup was never even attempted. Should I tweak things to only do an
audit when an actual cgroup change was attempted (perhaps by modifying
util/cgroup.c to return 0 on success, 1 on skip, and -errno on
failure, rather than the current -EINVAL on skip)?
This is post-0.8.8 material.

[libvirt] [PATCH] build: fix broken mingw cross-compilation
by Eric Blake
Two regressions:
Commit df1011ca broke builds for systems that lack devmapper
(non-Linux, as well as Linux with ./autogen.sh --without-libvirtd
and without the libraries present).
Commit ce6fd650 broke cross-compilation, due to a gnulib bug.
* .gnulib: Update to latest, for cross-compilation fix.
* src/util/util.c (virIsDevMapperDevice): Provide stub for
platforms not using storage driver.
* configure.ac (devmapper): Arrange to define HAVE_LIBDEVMAPPER_H.
devmapper issue reported by Wen Congyang.
---
Thankfully, neither regression was in the 0.8.7 release.
Pushing this under the build-breaker rule, as verified by
./autobuild.sh.
* .gnulib aa0f5d7...17adb5d (9):
> longlong: skip, rather than fail, on cross-compilation
> * NEWS: Mention 2011-02-08 change to stdlib.
> getloadavg: Add comments about platforms.
> getloadavg: Fix link error on Solaris 2.6.
> * lib/getloadavg.c (getloadavg) [sgi]: Make ldav_off of type ptrdiff_t.
> Oops, fix syntax error in last config.rpath commit.
> havelib: Fix comments.
> havelib: Update config.rpath.
> getloadavg test: Add some plausibility checks.
