[libvirt] Question about building libvirt.so
by vikhyath reddy 25 Feb '14

25 Feb '14

Hi, Thanks for libvirt. It is a life saver. I am in the process of writing some custom wrappers for libvirt so that it can be easily accessed from nodejs using the nodejs-ffi interfacing (basically describes a way to convert nodejs to c calls). I did write the wrapper on the lines of the examples provided. But I am unable to see my new functions in the libvirt.so file (which nodejs interfacing needs). Which means that my wrappers under <libvirt>/wrappers/ are not getting into libvirt.so like the ones at <libvirt>/examples Can you please guide me as to where I am going wrong? I was able to do a successful configure + make and I thought this will regenerate the new libvirt.so (which it does, but I cant see my new wrapper methods in it). Much appreciated, Thanks, vik.

[libvirt] [PATCH V2] libxl: queue domain event earlier in shutdown handler
by Jim Fehlig 25 Feb '14

25 Feb '14

The shutdown handler may restart a domain when handling a reboot event or when <on_*> is set to 'restart'. Restarting consists of calling libxlVmCleanup followed by libxlVmStart. libxlVmStart will emit a VIR_DOMAIN_EVENT_STARTED event, but the SHUTDOWN event is not emitted until exiting the shutdown handler, after the STARTED event. This patch changes the logic a bit to queue the event at the start of the shutdown action, ensuring it is queued before any subsequent events that may be generated while executing the shutdown action.

[libvirt] Compiling libvirt RPC client library for QNX
by Panday Ritesh Sharma (rpanday) 25 Feb '14

25 Feb '14

HI Team, I have downloaded the libvirt source code from libvirt_0.9.8.orig.tar.gz<https://launchpad.net/ubuntu/+archive/primary/+files/libvirt_0.9.8.orig.tar…> . I just wanted libvirt RPC client library to be compiled for QNX. My remote box which is running QNX would like to establish libvirt connection with linux box to launch virtual domains/VMs and would also like to get lifecycle events. Could you please let me know what all directory/files I need to compile which I have got from libvirt_0.9.8.orig.tar.gz<https://launchpad.net/ubuntu/+archive/primary/+files/libvirt_0.9.8.orig.tar…> ? While browsing through net I found the files available under src/util, src/conf, src/rpc, src/remote, are sufficient for client RPC library? Is this correct or I need to include any other files ? Is there any instruction or help available which I can use to compile this library for QNX ? Regards Ritesh Sharma

[libvirt] [PATCH 0/7] network: include plugged interface XML in "plugged" network hook
by Laine Stump 25 Feb '14

25 Feb '14

Although the immediate reason for all these patches is $subject, it really is something that should have been done a long time ago (I just hadn't convinced myself it was the right thing to do). These patches will allow a management application to easily learn exactly what physical hardware is being used by a domain's interface, which wasn't previously possible (e.g., it will be simple to learn which SRIOV VF is being used by a domain interface that is configured as <interface type='network'> where the network is a pool of VFs). Laine Stump (7): conf: clarify what is returned for actual bandwidth and vlan conf: handle null pointer in virNetDevVlanFormat conf: make virDomainNetDefFormat a public function conf: re-situate <bandwidth> element in <interface> conf: new function virDomainActualNetDefContentsFormat conf: output actual netdev status in <interface> XML network: include plugged interface XML in "plugged" network hook src/conf/domain_conf.c | 303 +++++++++++++-------- src/conf/domain_conf.h | 4 + src/conf/netdev_vlan_conf.c | 4 +- src/libvirt_private.syms | 1 + src/network/bridge_driver.c | 48 ++-- ...qemuhotplug-console-compat-2+console-virtio.xml | 4 +- .../qemuxml2argv-console-compat-2.xml | 4 +- .../qemuxml2argv-net-bandwidth.xml | 2 +- 8 files changed, 233 insertions(+), 137 deletions(-) -- 1.8.5.3

[libvirt] [PATCH 0/3] Various RBD storage pool changes
by Wido den Hollander 25 Feb '14

25 Feb '14

This series of patches changes a couple of things in the RBD storage pool driver. The first change is that it includes the return status of librados and librbd in log and debug messages making it easier for users to track down the real cause of the problem. The second patch simplifies some code. The third patch leverages the new timeout options from librados. Should the backing Ceph cluster not respond for any reason librados will timeout. This prevents libvirt from handing on a rados_* or rbd_* call and locking up libvirt. If the librados version on the system does not support these timeout options nothing happens. libvirt compiles and runs just fine, but the timeout simply won't work.
