Re: [libvirt] [libvirt-java] [PATCH 00/12] event support
by Stefan Majer
Hi,
back in January 2013 Claudio Bley submit a series of patches [1] to enable
event support to libvirt-java.
There was no response on his work and they didn't get merged.
Probably because there was not enough need out there.
But i would like to see this merged and had some conversion with Claudio
the last 2 weeks, i tested his work and can confirm it works. I have some
small additional, mostly cosmetic patches on top, but i would like to get
feedback from the list if there is a chance to get them merged.
So any comments and suggestions welcome !
Greetings

[libvirt] [libvirt PATCH] storage: Skip not active lv volumes
by Osier Yang
If the volume is of a clustered volume group, and not active, the
related pool APIs fails on open /dev/vg/lv. If the volume is suspended,
it hangs on open(2) the volume.
Though the best solution is to expose the volume status in volume
XML, and even better to provide API to active/deactive the volume,
but it's not the work I want to touch currently. Volume status in
other status is just fine to skip.
About the 5th field of lv_attr (from man lvs[8])
<quote>
5 State: (a)ctive, (s)uspended, (I)nvalid snapshot, invalid
(S)uspended snapshot, snapshot (m)erge failed,suspended
snapshot (M)erge failed, mapped (d)evice present without

Re: [libvirt] [libvirt-users] libvirt-snmp on Ubuntu
by george john
Thank you.
I was able to compile/install libvirt-snmp on Ubuntu by mainly following the instructions on:
http://lost-and-found-narihiro.blogspot.com/2013/01/how-to-install-libvir...
When I check the data returned by snmpwalk, I find that values for the UUID of the Virtual Guest, libvirtGuestUUID(1.3.6.1.4.1.12345.1.1.1.1) are not getting populated. This is a key piece of information. Does anyone know why this is not being populated?
Also I noticed that the value returned by libvirtGuestMemoryCurrent (current memory usage by VirtualGuest) is not the correct value. The value returned by this is same as libvirtGuestMemoryLimit (The maximum amount of memory (in MiB) that can be used by the virtual guest.).
Thanks.

[libvirt] [PATCH-v5.1] Support for static routes on a virtual bridge
by Gene Czarcinski
network: static route support for <network>
This update includes Laine Stump's comments/suggestions. Once
again he has improved my over-engineered solutions. My original
patch and his patch have been squashed/merged with this being the
result. That plus a little simplified code added to
bridge_driver.c to handle the zero address situations.
This code does not restrict any combination of
address/netmask/prefix for a static route specification. The
metric attribute has been added so that existing route specifications
can be overridden.
Documentation has been updated to reflect a v1.0.6 target.
This patch adds the <route> subelement of <network> to define a static
route. the address and prefix (or netmask) attribute identify the
destination network, and the gateway attribute specifies the next hop
address (which must be directly reachable from the containing
<network>) which is to receive the packets destined for
"address/(prefix|netmask)".
Tests are done to validate that the input definitions are
correct. For example, for a static route ip definition,
the address must be a network address and not a host address.
Additional checks are added to ensure that the specified gateway
is directly reachable via a network defined on this bridge.
The command used is of the following form:
ip route add <address>/<prefix> via <gateway> dev <virbr-bridge> \
proto static metric 1
For family='ipv4' address='0.0.0.0' netmask='0.0.0.0' or prefix='0' is
supported.
For family='ipv6' address='::' prefix=0' is supported.
Anytime an attempt is made to define a static route which duplicates
an existing static route (for example, address=::, prefix=0, metric=1),
the following error message will be sent to syslog:
RTNETLINK answers: File exists
This can be overridden by increasing the value of metric. Caution should
be used when doing this ... especially for a default route.
Note: The use of the command-line interface should be replaced by
direct use of libnl so that error conditions can be handled better. But,
that is being left as an exersize for another day.
.

+ Static route definitions are used to provide routing
+ information to the virtualization host for networks which are not
+ defined as a network on one of the virtual bridges so that such
+ networks can be reachable from the virtualization
+ host <span class="since">Since 1.0.6</span>.
+ </p>
+
+ <p>
+ As shown in <a href="formatnetwork.html#examplesNoGateway">this example</a>,
+ it is possible to define a virtual bridge interface with no
+ IPv4 or IPv6 networks. Such interfaces are useful in supporting
+ networks which have no visibility or direct connectivity with the
+ virtualization host, but can be used to support
+ virtual networks which only have guest connectivity. A guest
+ with connectivity to the guest-only network and another network
+ that is directly reachable from the host can act as a gateway between the
+ networks. A static route added to the "visible" network definition
+ provides the routing information so that IP packets can be sent
+ from the virtualization host to guests on the hidden network.
+ </p>
+
+ <p>
+ Here is a fragment of a definition which shows the static
+ route specification as well as the IPv4 and IPv6 definitions
+ for network addresses which are referred to in the
+ <code>gateway</code> gateway address specifications. Note
+ that the third static route specification includes the
+ <code>metric</code> attribute specification with a value of 2.
+ This indicates that this particular definition is overriding another
+ route definition with the same address and prefix but with a lower
+ value for the metric.

[libvirt] [PATCH] qemu: allocate network connections sooner during domain startup
by Laine Stump
VFIO device assignment requires a cgroup ACL to be setup for access to
the /dev/vfio/nn "group" device for any devices that will be assigned
to a guest. In the case of a host device that is allocated from a
pool, it was being allocated during qemuBuildCommandLine(), which is
called by qemuProcessStart() *after* the all-encompassing
qemuSetupCgroup() is called, meaning that the standard Cgroup ACL
setup wasn't catching these devices allocated from pools.
One possible solution was to manually add a single ACL down inside
qemuBuildCommandLine() when networkAllocateActualDevice() is called,
but that has two problems: 1) the function that adds the cgroup ACL
requires a virDomainObjPtr, which isn't available in
qemuBuildCommandLine(), and 2) we really shouldn't be doing network
device setup inside qemuBuildCommandLine() anyway.
Instead, I've created a new function called
qemuNetworkPrepareDevices() which is called just before
qemuPrepareHostDevices() during qemuProcessStart() (explanation of
ordering in the comments), i.e. well before the call to
qemuSetupCgroup(). To minimize code churn in a patch that will be
backported to 1.0.5-maint, qemuNetworkPrepareDevices only does
networkAllocateActualDevice() and the bare amount of setup required
for type='hostdev network devices.
Note that some of the code that was previously needed in
qemuBuildCommandLine() is no longer required when
networkAllocateActualDevice() is called earlier:
* qemuAssignDeviceHostdevAlias() is already done further down in
qemuProcessStart().
* qemuPrepareHostdevPCIDevices() is called by
qemuPrepareHostDevices() which is called after
qemuNetworkPrepareDevices() in qemuProcessStart().
This new function should be moved into a separate qemu_network.c (or
similarly named) file along with qemuPhysIfaceConnect(),
qemuNetworkIfaceConnect(), and qemuOpenVhostNet(), and expanded to call
those functions as well, then the nnets loop in qemuBuildCommandLine() should
be reduced to only build the commandline string. However, this will
require storing away an array of tapfd and vhostfd that are needed
for the commandline, so I would rather do that in a separate patch and
leave this patch at the minimum to fix the bug.

[libvirt] Bug in DOMINFO command when balloon driver is used on a vm with more then 8 GB of MaxMemory ?
by fc lists
Hi ,
I have been banging my head on this for the last 8 hours ... and i really
need to know if is really a bug or i am doing something wrong.
Description of the problem:
When the virsh setmem command is used to inflate the balloon on a VM to
which 8GB of MaxMemory or more are allocated then the information reported
with virsh dominfo , virsh dumpxml after the balloon change has been
performed are wrong.
The actual balloon is inflated correctly though and that is verifiable both
in the vm itself and through the "virsh dommemstat" commands.
I *think* that is because the dommestat command will perform a proper query

but no entries are shown in the log for qemu-monitor when virsh dominfo is
run, how does dominfo gather those informations?
I am going to raise a ticket on RED HAT bugzilla for this but was hoping to
get some feedback here first to avoid raising a ticket for something that
maybe i just misunderstood.
Platform is Centos 6.4 (problem was present in 6.3 as well starting
with libvirt-0.9.10-21.el6.3.7 )
The patch that actually is causing the problem is patch number 398 in the
src rpm for libvirt-0.9.10-21.el6.3.7 :
libvirt-Wire-up-handling-for-QMP-s-BALLOON_EVENT.patch (
https://bugzilla.redhat.com/show_bug.cgi?id=884713)
And i verified it by removing the patch and recompiling the rpm , that
indeed worked perfectly after that.
The problem exists in every version up to the latest (that is what i am
running now) but now the patch is part of the libvirt source code in itself
and not a patch in the rpm anymore.

[libvirt] ANNOUNCE: libvirt-sandbox "Nubian Desert" release 0.2.0
by Daniel P. Berrange
I pleased to announce the a new public release of libvirt-sandbox,
version 0.2.0, is now available for download
ftp://libvirt.org/libvirt/sandbox/
The packages are GPG signed with
Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R)
The libvirt-sandbox package provides an API layer on top of libvirt-gobject
which facilitates the cration of application sandboxes using virtualization
technology. An application sandbox is a virtual machine or container that
runs a single application binary, directly from the host OS filesystem.
In other words there is no separate guest operating system install to build
or manager.
At this point in time libvirt-sandbox can create sandboxes using either LXC
or KVM, and should in theory be extendable to any libvirt driver. This
release has focused entirely on improving the virt-sandbox-service tool
Changed in this release:
- Requires systemd >= 198
- Fix termination of interactive sandbox client to
avoid loosing final I/O
- Stop hardcoding default security label
- Misc docs typos / fixes
- Fix infinite loop handling security opts
- Mandate enablement of introspection
- Handle NULL broadcast address for NICs
- Don't assume /var/log/journal exists
- Improve rollback if creation of service sandbox fails
- Block host NICs from sandbox
- Sanity check requested network config
- Fix sandbox journal location to be a dir not a file
- Fix parsing of --security option
- Change virt-sandbox-service to use --security opts
instead of SELinux specific -l/-t/-d args
- Replace use of YUM with RPM to improve performance
- Send dhclient output to /dev/null
- Avoid getting stuck in waitpid if non-primary process
exits
- Allow choice of host virtual networks
- Support network config with virt-sandbox-service
- Do not create any NIC in service sandbox by default
- Cope with SELinux label lacking a category pair
- Delay dropping credentials until after ttys are opened
- Fix tty permissions in QEMU init helper to be 0700 instead
of 0777
- Add support for non-systemd service containers
- Add support for i18n of all output strings
- Remove hardcoding of lxc:/// in virt-sandbox-service
- Correctly handle EOF from raw console
- Improve I/O performance of virt-sandbox
- Allow custom uid/gid for generic service sandboxes
- Do not run debug shell in service sandboxes
- Add --package option to virt-sandbox-service for cases
where the unit file is not owned by an RPM
- Use drop in systemd service override, instead of
includes
- Support templated systemd service units
Thanks to everyone who contributed to this release
Regards,
Daniel
