[Libvir] PATCH: 0/16: Storage management APIs
by Daniel P. Berrange
The patch series that follows provides storage management APIs for dealing
with local directories, local filesystems, remote filesystems, logical
volumes (LVM), disk partitioning, and iSCSI. It will also soon support
SCSI host adapters (including NPIV).
I'll include comments inline with each patch. The final patch in the
series also provides a 'storage.html' page for the website giving a fairly
friendly overview of the storage pool types and their associated XML
examples.
Although included here, the one API i really don't like is the one for
discovery virConnectDiscoverStoragePools, since its API is not flexible
enough in terms of metadata it accepts. I will probably just leave this
out next time around, since its not critical for the core functionality
and can thus be added later.
Also TBD is a way to format a filesystem on a volume, and how to clone
an existing volume, and take a snapshot. These things can all be added
at a later date.
Finally it does not include the async job support. This is also best added
once the core code is merged.
Dan.

[Libvir] [PATCH] Avoid "make syntax-check" failure.
by Jim Meyering
There were a few trailing blanks in a generated Makefile.am file.
This patch fixes the python script not to emit the offending spaces:
Avoid "make syntax-check" failure.
* docs/examples/index.py: Don't emit trailing blanks.
* docs/examples/Makefile.am: Regenerate.

[Libvir] Deprecated PolicyKit function
by Mark McLoughlin
Hi,
Just a heads-up ... trying to build with -Werror on Fedora rawhide, I
see:
cc1: warnings being treated as errors
remote.c: In function 'remoteDispatchAuthPolkit':
remote.c:2661: error: 'polkit_context_can_caller_do_action' is deprecated (declared at /usr/include/PolicyKit/polkit/polkit-context.h:173)
Cheers,
Mark.

[Libvir] Dependent Xen and Libvirt patches?
by Ryan Scott
Hi all,
I have a question about compatibility issues when submitting changes
to both Xen and libvirt.
First, some background: I'm seeing a problem with virsh detach-disk.
It'll detach a disk from a running domain, but not update the domain's
configuration, so the disk will be back when the domain is rebooted.
This seems undesirable; I think the disk should be permanently removed
by virsh detach-disk.
To fix this, patches are necessary in both Xen and Libvirt.
First, the Xen patch:
--- old/tools/python/xen/xend/server/SrvDomain.py
+++ new/tools/python/xen/xend/server/SrvDomain.py
@@ -186,7 +186,9 @@

def op_device_configure(self, _, req):
Next, the libvirt patch:

}
Now, on to my question: I want to make sure I can do this without
causing too many problems. In my testing, the libvirt change without
the xen change won't cause any additional issues, but the xen change
without the libvirt change will cause all 'virsh detach-disk' calls to fail.
How should a change like this be handled? Submit the libvirt patch
now, and sit on the Xen patch for a while? Or submit both and include a
note that an upgrade will be necessary?
Thanks,
Ryan

[Libvir] Announcing oVirt
by Hugh O. Brock
Announcing oVirt
================
It is my pleasure to announce oVirt, the next step in open virtual
machine management.
oVirt is:
* A small OS image that runs libvirt and hosts virtual machines
* A Web-based virtual machine management console
oVirt goals:
* Empower virtual machine owners without giving up control of
hardware
* Automate virtual machine clustering, load balancing, and SLA
maintenance
* Simplify management of large numbers of machines
* Work across platforms and architectures
oVirt uses:
* A kerberos/LDAP server for authentication and authorization
(oVirt ships with FreeIPA)
* DNS/DHCP services on the local LAN -- or provides them for oVirt
hosts over a private network if desired
* Libvirt for virtual machine management, storage management, and
secure remote communication
* collectd for stats gathering and monitoring
* Rails for rapid, flexible development
oVirt mailing list: http://www.redhat.com/mailman/listinfo/ovirt-devel
oVirt IRC: irc.freenode.net/#ovirt
oVirt website: http://ovirt.org
We encourage anyone interested to download the source (git clone
git://git.et.redhat.com/ovirt) or the prebuilt appliance
(http://ovirt.org/download). Let us know what you think!
Enjoy,

[Libvir] [PATCH] Pull useless-if-before-free from gnulib, and update.
by Jim Meyering
I added a slightly improved useless-if-before-free to gnulib, so this
patch makes bootstrap pull the script from there. It also pulls in a
vasnprintf module improvement: it works around a just-discovered bug in
HPUX 10.20's printf(3) implementation:
http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/12505/focus=12547
Here's the patch:
Pull useless-if-before-free from gnulib, and update.
* bootstrap (gnulib_tool): Add useless-if-before-free to
the list of modules.
* build-aux/useless-if-before-free: Update from gnulib.
* gnulib/lib/vasnprintf.c: Work around a bug in HPUX 10.20.
* gnulib/m4/vasnprintf.m4: Likewise.

[Libvir] [PATCH] Enable another syntax-check rule.
by Jim Meyering
This one makes sure we don't use the "#ifdef HAVE_CONFIG_H" meme:
Enable another syntax-check rule.
* Makefile.cfg (local-checks-to-skip): Remove sc_no_have_config_h.
* qemud/mdns.c: Remove "#ifdef HAVE_CONFIG_H".
* Makefile.maint (sc_no_have_config_h): Tighten up regexp,
so that the above mention of "HAVE_CONFIG_H" doesn't match.
* .x-sc_no_have_config_h: New file, to exempt gnulib/ straggler.

[Libvir] New XML attributes for virtio
by Soren Hansen
Hi!
I filed https://bugzilla.redhat.com/show_bug.cgi?id=431063 yesterday to
track this issue.
Quoting the bug report:
"To use the new virtio capabilites available in kvm 60, special command
line paramaters need to be passed to kvm. There should be a way to
specify that a device should use virtio in the libvirt xml.
I propose adding a "model" attribute to the interface element in the XML
to be able to specify the type of NIC to emulate, e.g. 'virtio'.
For the disk virtio I propose adding an 'interface' attribute to target
element (inside the disk element). This interface could then be set to
'virtio', 'ide', 'scsi', etc.."
Since I wrote the bug report, I noticed there's no way to specify which
graphics card, you'd like to emulate. A 'model' attribute could probably
be added to the graphics element as well.
Comments?

[Libvir] dumpxml define not idempotent due to <bootlader/> tag
by Guido Guenther
Hi,
when using "virsh dumpxml <domain> > xmlfile" on a running paravirt xen
domain that has no bootloader entry whatsoever I get:
...
<bootloader/>
<os>
<type>linux</type>
<kernel>/boot/vmlinuz-vm</kernel>
<initrd>/boot/initrd.img-vm</initrd>
<cmdline>root=/dev/sda1 ro </cmdline>
</os>
...
reimporting this via "virsh define xmlfile" and then dumping again gives
something like:
...
<bootloader/>
<os>
<type>linux</type>
</os>
...
since a bootloader tag is found the kernel and initrd entries are being
dropped. My hack is to ignore empty bootloader statements for the
moment:

Would that be the right place to fix this?
