[libvirt] [PATCH] network: don't allow multiple dhcp sections
by Kyle DeFrancia
This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=907779
A <dhcp> element can exist in only one IPv4 address and one IPv6
address per network. This patch enforces that in virNetworkUpdate.

[libvirt] [PATCH] cpu-driver: Fix the cross driver function call
by Daniel Hansel
For Intel and PowerPC the implementation is calling a cpu driver
function across driver layers (i.e. from qemu driver directly to cpu
driver).
The correct behavior is to use libvirt API functionality to perform such
a inter-driver call.
This patch introduces a new cpu driver API function getModels() to
retrieve the cpu models. The currect implementation to process the
cpu_map XML content is transferred to the INTEL and PowerPC cpu driver
specific API functions.
Additionally processing the cpu_map XML file is not safe due to the fact
that the cpu map does not exist for all architectures. Therefore it is
better to encapsulate the processing in the architecture specific cpu
drivers.

[libvirt] [PATCH] qemu: Fix virsh freeze when blockcopy storage file is removed
by Erik Skultety
If someone removes blockcopy storage file when still in mirroring phase
and then requesting blockjob abort using pivot, virsh cmd freezes. This
is not an issue with older qemu versions which did not support
asynchronous jobs (which we prefer by default).
As we have reached the mirroring phase successfully, polling monitor for
blockjob info always returns 1 and the loop never ends.
This fix introduces a check for qemuDomainBlockPivot return code, possibly
skipping the asynchronous waiting completely, if an error occured and
asynchronous waiting was the preferred method.

[libvirt] [PATCH] network: Let domains be restricted to local DNS
by Josh Stone
This adds a new "localOnly" attribute on the domain element of the
network xml. With this set to "yes", DNS requests under that domain
will only be resolved by libvirt's dnsmasq, never forwarded upstream.
This was how it worked before commit f69a6b987d616, and I found that
functionality useful. For example, I have my host's NetworkManager
dnsmasq configured to forward that domain to libvirt's dnsmasq, so I can
easily resolve guest names from outside. But if libvirt's dnsmasq
doesn't know a name and forwards it to the host, I'd get an endless
forwarding loop. Now I can set localOnly="yes" to prevent the loop.

[libvirt] [PATCH] docs: More html/docs changes from libvirt.h.in split
by John Ferlan
This changes the display from:
libvirt-storage: APIs for management of storages
to
libvirt-storage: APIs for management of storage pools and volumes
In making that change I expected my build tree html output to be
regenerated; however, it wasn't because the dependency for the separated
libvirt-storage.h wasn't there. It was only present for libvirt.h.in
So I added each in the order displayed on the docs/html/index.html page

[libvirt] how to pin disk order when adding SATA disk with virt-manager ?
by Jason Vas Dias
Hi - this is my first post to this list - sorry if this is a newbie
question, but:
I want to mount 7 LVM disk volumes under my guest :
Physical Host Volume: Guest Device: Guest FS:
/dev/mapper/VG_A-vol1 : /dev/sda : /root file system
/dev/mapper/VG_S-swap2 : swap : swap partition
/dev/mapper/VG_C-vol3 : /dev/sdc : /home file system
/dev/mapper/VG_G-vol7 : /dev/sdg : /x some necessary other storage
I am booting with the "Direct Boot" option and kernel command line
containing "root=/dev/sda" - ie. there HAS to be some particular /dev/sdX
where X is the virtual order of the disks on the virtual SATA bus / device
minor number to letter mapping .
Every time I add a new volume via the virt-manager the ordering of ALL
disks change , and I must manually discover which drive letter
('a-g' in /dev/sd[a-g]) maps to which disk , even though the ordering as
shown in the GUI remains the same - ie. when I click on the 'SATA Disk 1'
icon in the virt-manager 'Details...' tab, it still shows the correct LVM
is associated with Disk 1, but the system does not boot because what
was '/dev/sda' is now '/dev/sdb' .
Is this a bug ? Can I request a "New Feature" which would allow me
to specify the "Bus Sequence Number" in the Virtual Disk panel
(where I currently can specify Source Path, Disk Bus, Advanced Options etc...
) - surely you could let users map disks to devices in a way that does not
change with each new disk added ?
Anyway, that's my 2 cents on $subject .
Any thoughts / suggestions gratefully received .
Thanks & Regards ,
Jason

[libvirt] [PATCH] cpu: fix possible crash in getModels
by Pavel Hrdina
Commit 86a15a25 introduced a new cpu driver API 'getModels'. Public API
allow you to pass NULL for models to get only number of existing models.
However the new code will crash with segfault so we have to count with
the possibility that the user wants only the number.
There is also difference in order of the models gathered by this new API
as the old approach was inserting the elements to the end of the array
so we should use 'VIR_APPEND_ELEMENT'.
