[libvirt] how to install 'devel' module from source files...
by john alexander sanabria ordonez
Hi,
I'm wondering how, when libvirt is installed from sources, to also install
the 'development' files?
I installed libvirt-0.8.8 with no problems and 'virsh' works OK. However,
when I try to install, for instance libvirt-ruby, it asks me for libvirt
development files.
What extra step is required?
Thanks,

[libvirt] [PATCH 1/2] build: fix build on cygwin
by Eric Blake
On cygwin:
CC libvirt_util_la-cgroup.lo
util/cgroup.c: In function 'virCgroupKillRecursiveInternal':
util/cgroup.c:1458: warning: implicit declaration of function 'virCgroupNew' [-Wimplicit-function-declaration]
* src/util/cgroup.c (virCgroupKill): Don't build on platforms
where virCgroupNew is unsupported.
---
Pushing under the build-breaker rule. And this time, it really
was a cygwin failure ;)

[libvirt] [RFC PATCH] cgroup: allow fine-tuning of device ACL permissions
by Eric Blake
Adding audit points showed that we were granting too much privilege
to qemu; it should not need any mknod rights to recreate any
devices other than ptys. On the other hand, lxc should have all
device privileges. The solution is adding a flag parameter.
* src/util/cgroup.h (virCgroup*Device*): Adjust prototypes.
* src/util/cgroup.c (virCgroupAllowDevice)
(virCgroupAllowDeviceMajor, virCgroupAllowDevicePath)
(virCgroupDenyDevice, virCgroupDenyDeviceMajor)
(virCgroupDenyDevicePath): Add parameter.
* src/qemu/qemu_cgroup.c: Update clients.
* src/qemu/qemu_driver.c (qemudDomainSaveFlag): Likewise.
* src/lxc/lxc_controller.c (lxcSetContainerResources): Likewise.
---
https://bugzilla.redhat.com/show_bug.cgi?id=683163 was created
based on my audit patches.
RFC for two reasons:
This patch won't apply unless you have my other pending qemu audit
patches in place (I still need to post those, but ran out of time
for now...)
I need to do a followup patch to also restrict write access to
a disk explicitly marked read-only from qemu's point of view.
But I wanted to at least get this email posted to start feedback.

[libvirt] Fix cygwin build

In virLogEmergencyDumpAll I was using SIGBUS and SIGUSR2, and
apparently they arent; defined on cygwin signal.h header. I decided to
make the code conditional for all of them and not just those two for
portability sake. I resisted doing this on the daemon side because as
far as I know we don't compile it on WIN32. So I just pushed the
following under the build breaking rule,

In addition, we ensure const-correctness of vshCommandOptString function and
related code.

[libvirt] [RFC PATCH 0/5] Allow data upload/download to/from storage volumes
by Daniel P. Berrange
This patch series introduces two new APIs to allow data upload/download
to/from storage volumes, using the streams APIs. Mostly I wrote this so
I had an easier way to test the streams handling in my RPC patch series
than using QEMU tunnelled migration code. Cole has expressed an interest
in this kind of functionality in the past to allow virt-manager to upload
kernel/initrd to remote hosts for provisioning guests.
Most of the code here is pretty boring & trivial. The first patch is the
one that is remotely interesting. One might argue we should just spawn
'dd' instead of this, but dd has some annoying aspects (you can't control
its write offset in units smaller than the block size) and this could be
useful more broadly.

[libvirt] [PATCH 0/3] device-detaching with generated mac
by Michal Privoznik
When detaching interface via detach-device or virDomainDetachDevice() we
parse input XML and (probably) generate a random MAC. This leads then into
not finding interface and thus error. When a mac wasn't specified and domain
has exactly one interface, semantic is clear. Otherwise we require <mac> in
input XML.
Michal Privoznik (3):
Introduce flag representing if MAC address of interface was generated
or not.
qemu: Check for generated MACs while detaching interface
xen: Check for generated MACs while detaching interface
