3. lxcDomainDetachDevice
4. lxcDomainDetachDeviceFlags
5. lxcDomainUpdateDeviceFlags
In live mode, set devices.allow/deny to instance's cgroup and insert
disk config into current domain.
In config mode, just insert disk config into current domain.

[libvirt] [PATCH] Add cpu thread siblings information to virsh capabilities.
by Dusty Mabe 24 Oct '12
by Dusty Mabe 24 Oct '12
24 Oct '12
This patch is an attempt to add cpu hyperthreaded siblings information
to the output from virsh capabilities output. The information will
directly mirror the contents of the
/sys/devices/system/cpu/cpuN/topology/thread_siblings_list
files. The new output of virsh capabilities will look like:
<topology>
<cells num='2'>
<cell id='0'>
<cpus num='12'>
<cpu id='0' thread_siblings='0,12'/>
.
.
</cpus>
</cell>
</cells>
</topology>
This patch is my first attempt at patching libvirt so forgive me if I
make some novice mistakes.

[libvirt] [PATCH] Refactor ESX storage driver and add iSCSI support
by Ata E Husain Bohra 24 Oct '12
by Ata E Husain Bohra 24 Oct '12
24 Oct '12
The patch refactors the current ESX storage driver due to following reasons:
1. Given most of the public APIs exposed by the storage driver in Libvirt
remains same, ESX storage driver should not implement logic specific
for only one supported format (current implementation only supports VMFS).
2. Decoupling interface from specific storage implementation gives us an
extensible design to hook implementation for other supported storage
formats.
This patch refactors the current driver to implement it as a facade pattern i.e.
the driver exposes all the public libvirt APIs, but uses backend drivers to get
the required task done. The backend drivers provide implementation specific to
the type of storage device.
File changes:
------------------
esx_storage_driver.c ----> esx_storage_driver.c (base storage driver)
|
|---> esx_storage_backend_vmfs.c (VMFS backend)
|
|---> esx_storage_backend_iscsi.c (iSCSI backend)
The patch adds the backend driver to support iSCSI format storage pools
and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt
is as follows:
1. ESX static iSCSI target <------> Libvirt Storage Pools
2. ESX iSCSI LUNs <------> Libvirt Storage Volumes.
The above understanding is based on http://libvirt.org/storage.html.
The operation supported on iSCSI pools includes:
1. List storage pools & volumes.
2. Get xml descriptor operaion on pools & volumes.
3. Lookup operation on pools & volumes by name, uuid and path (if applicable).
iSCSI pools does not support operations such as: Create / remove pools
and volumes

[libvirt] [PATCHv5 0/3] Transport Open vSwitch per-port data during live migration
by Laine Stump 24 Oct '12
by Laine Stump 24 Oct '12
24 Oct '12
In-Reply-To:
This is an update (of an update :-) of Kyle Mestery's patch series v3
by the same name:
https://www.redhat.com/archives/libvir-list/2012-October/msg00014.html
I've updated it according to the comments in the review of patch 1/3
of that series:
https://www.redhat.com/archives/libvir-list/2012-October/msg01224.html
and also according to Michal and Eric's comments on v4:
https://www.redhat.com/archives/libvir-list/2012-October/msg01227.html
(interdiffs for those last changes are attached to patches 1/3 and 2/3)
It now needs a counter-review from Kyle, along with verification that
it actually works (since I don't have the proper setup to test it
handy).
******************************************
This series of commits has the end goal of allowing per-port data stored
in the Open vSwitch DB to be transported during live migration. This is
done by first providing a generic infrastructure for transporting network
data, adding some utility functions specific to Open vSwitch, and hooking
the two together.
The framework provided is generic in that other networking data could be
transferred as well by simply adding in additional hooks as needed.
Kyle Mestery (3):
Add the ability for the Qemu V3 migration protocol to include
transporting network configuration. A generic framework is proposed
with this patch to allow for the transfer of opaque data.
Add utility functions for Open vSwitch to both save per-port data
before a live migration, and restore the per-port data after a
live migration.
Transport Open vSwitch per-port data during live migration by
using the utility functions
virNetDevOpenvswitchGetMigrateData() and
virNetDevOpenvswitchSetMigrateData().
****************************************************************

* remove extra {} in one place, add them in a couple others (I like
braces when the condition is multi-line too).

In commit 371ddc98, I mistakenly added the check for sysctl
version 9 after setting the hypercall version to 1, which will
fail with
error : xenHypervisorDoV1Op:967 : Unable to issue hypervisor
ioctl 3166208: Function not implemented
This check should be included along with the others that use
hypercall version 2.

PATCH 01/12 defines a couple new macros/functions to simplify
inserting/deleting items in the middle of an array. The remaining
patches switch over various pieces of existing code to use these new
macros rather than directly calling memmove, etc.
There are several other places where these macros could *almost* be
used, except that they use the model of pre-allocating the larger
array, then performing a bunch of operations (that may fail) and then
finally move items around in the array and adjust its count. I'm
wondering if I should add a flags arg to these to allow for specifying
a "Don't realloc" flag - when it was given, the memory allocation
operation would be presumed already done (in the case of insert) or to
be done after return (for delete). Any opinions on that?

[libvirt] [PATCH] xml: omit domain name from comment if it contains double hyphen
by Ján Tomko 24 Oct '12
by Ján Tomko 24 Oct '12
24 Oct '12
We put a comment containing "virsh edit <domain_name>" at the start of
the XML. W3C recommendation forbids the use of "--" in comments [1] and
libvirt can't parse it either. This patch omits the domain name if it
contains a double hyphen.

Rename the 'wait' parameter to 'loop'.
This silences the warning:
storage/storage_backend.c:1348:34: error: declaration of 'wait' shadows
a global declaration [-Werror=shadow]
and fixes the build with -Werror.

Note: loop is pool backwards.

Hello,
Currently, libvirt is not support device operations for lxc.
This is a patch that add device operations support for libvirt 0.10.2.
1. lxcDomainAttachDevice
2. lxcDomainAttachDeviceFlags
3. lxcDomainDetachDevice
4. lxcDomainDetachDeviceFlags
5. lxcDomainUpdateDeviceFlags
In live mode, set devices.allow/deny to instance's cgroup and insert
disk config into current domain.
In config mode, just insert disk config into current domain.
This is part of 'Fix up attach/detach volume for nova (openstack)'.
Please see: https://bugzilla.redhat.com/show_bug.cgi?id=869259

Best regards!

Currently consumers of libvirt's APIs must assume/attempt to define a
VM that uses spice, vnc, or sdl without knowing if the actual
hypervisor supports it. Obviously my discussion is very QEMU oriented
but it would be good to leave expansion for the future. I was thinking
that under the <guest> element for the capabilities we can add
something like:
<graphics>
<spice/>
<vnc/>
<sdl/>
</graphics>
It would be at the same level as <arch> and <features>. But before I
implemented this I wanted a sanity check if people think this is the
best place or the best naming convention.
Thanks.

Currently, we use iohelper when saving/restoring a domain.
However, if there's some kind of error (like I/O) it is not
propagated to libvirt. Since it is not qemu who is doing
the actual write() it will not get error. The iohelper does.
Therefore we should check for iohelper errors as it makes
libvirt more user friendly.

[libvirt] [PATCH v2] put dnsmasq parameters into a file instead of the command line
by Gene Czarcinski 23 Oct '12
by Gene Czarcinski 23 Oct '12
23 Oct '12
This patch changes the way parameters are passed to dnsmasq. They are
put into a conf-file instead of being on the dnsmasq command line.
**NOTE ** This has updated the related tests for the new
data format, etc.
**NOTE** This patch does NOT include specifying interface=
The command line now contains --conf-file=<filename> and a new
parameter --conf-dir=<directoryname> has been added.
The new file and directory are put in the same directory as the
leases file.

Hi all,
Is anyone up for being the new owner/maintainer for libvirt
on OSX MacPorts?
The MacPorts guys have pinged us, suggesting we update the
libvirt port there to something recent:
https://trac.macports.org/ticket/36691
I'm still very engaged on the Homebrew side, but have next
to no interest in MacPorts so am looking to pass it on. :)
?
Regards and best wishes,
Justin Clift

I am pretty much complete creating a patch which changes how dnsmasq is
started by moving the command line parameters into a conf file. This new
file is placed into the same directory and the lease file.
The test for the command line arguments now checks the contents of the
conf-file and there is no longer any tests for the command line
parameters which are now two.
The first command line parameter is (naturally) --conf-file=<filename>.
The second parameter adds new functionality and is
--conf-dir=<directory>. This directory is placed into the same
directory as the conf-file and the lease file. The name of this
directory is "<net-name>.d". This was added to make testing/debugging of
new dnsmasq options easier since it no longer requires rebuilding the
binaries. This is also useful for adding log-dhcp and/or log-queries
for a specific network.
Now the option question. I can submit the patch assuming the my
previously submitted patch to add --interface to the command line has
been applied or I can assume that it has not been applied. In either
case, the new code adds a interface=<dev-name> to the conf-file.
All development and testing was done with 0.10.2 libvirt src.rpm on
Fedora 17.
The patch will be submitted based on git.

[libvirt] [PATCHv2] Fix disabling of apparmor/selinux security drivers
by Christophe Fergeau 23 Oct '12
by Christophe Fergeau 23 Oct '12
23 Oct '12
When using --without-$name --without-secdriver-$name with $name being
selinux or apparmor, configure will fail saying that AppArmor/SELinux
development package must be installed.
This is caused by a small bug in --with-secdriver-$name handling in
configure.ac which treats --without-secdriver-$name when $name as if the
user had requested to enable $name when $name couldn't be detected on
the system.
This commit also makes sure the detection checks for disabled
secdrivers do not needlessly get run, especially as this could
cause an error as well in --with-$name --without-secdriver-$name
situations.

Hi,
I installed Virtual box software in linux open suse. Unable to connect to
the
vbox hypervisor driver.
Version-Release number of selected component (if applicable):
libvirt-0.9.0
How reproducible:
when i am giving the following command for virsh:
virsh -connect vbox:///session then the following error is coming.
error: no hypervisor driver available for vbox:///session
error: failed to connect to the hypervisor
Even I installed virtualbox the above error is coming. I am not able to
find vbox hypervisor driver. Can anyone suggest where can i find vbox
dirver.
Awaiting Response
Thanks and Regards,
Srinivas.

Hi,
I installed Libvirt. We need virtualbox support for libvirt. But we are
unable to see the vbox option in virt-manager. How we can find vbox
hypervisor driver?
And also we already compiled libvirt with vbox option.(--with-vbox). But
that didn't work. And also when we are creating the new virtual machine
through virt-manager we are getting the following error:
internal error cannot parse QEMU version number in ""
Can you please suggest on this what we need to do as soon as possible?
Thanks in advance.
Srinivas

hurt to have the latest going into a freeze for 1.0.0.

The snapshot code when reusing an existing file had hard-to-read
logic, as well as a missing sanity check: REUSE_EXT should require
the destination to already be present.
* src/qemu/qemu_driver.c (qemuDomainSnapshotDiskPrepare): Require
destination on REUSE_EXT, rename variable for legibility.
---
v9: separate out from larger series, as this one is ready now;
provide diff with more context and a renamed variable.

help to create disk images copy-storage-* required,
try to do non-shared migration without bothering to
create disk images at target by hand.
consider this situation:
1. non-shared migration
virsh migrate --copy-storage-all ...
2. migration fails
3. create disk images required
qemu-img create ...
4 migration run smoothly
so, try do remove step 2, 3, 4
this kind of usage had been discussed before,
http://www.redhat.com/archives/libvir-list/2011-December/msg00451.html
maybe there're some flaws:
- It did not handle more about complete situations
suggested by Daniel P. Berrange,
https://www.redhat.com/archives/libvir-list/2012-October/msg00407.html
but may try to take care of them later.
so, now only normal disk image files be handled.
- for creation of disk images, size was setting as 0xffffffff boldly,
hope it can consolidate qemu, haven't constructed a comfortable
idea to solve it.

[libvirt] [PATCH 0/3] Transport Open vSwitch per-port data during live migration
by Kyle Mestery 23 Oct '12
by Kyle Mestery 23 Oct '12
23 Oct '12
This series of commits has the end goal of allowing per-port data stored
in the Open vSwitch DB to be transported during live migration. This is
done by first providing a generic infrastructure for transporting network
data, adding some utility functions specific to Open vSwitch, and hooking
the two together.
The framework provided is generic in that other networking data could be
transferred as well by simply adding in additional hooks as needed.
Kyle Mestery (3):
Add the ability for the Qemu V3 migration protocol to include
transporting network configuration. A generic framework is proposed
with this patch to allow for the transfer of opaque data.
Add utility functions for Open vSwitch to both save per-port data
before a live migration, and restore the per-port data after a
live migration.
Transport Open vSwitch per-port data during live migration by
using the utility functions
virNetDevOpenvswitchGetMigrateData() and
virNetDevOpenvswitchSetMigrateData().
