[libvirt] [PATCH v2] travis: switch to using Ubuntu 16.04 and 18.04
by Daniel P. Berrangé 07 Jun '18

07 Jun '18

The container images provided by Travis only support Ubuntu 14.04, however, Travis has ability to run docker, which allows the build script to use arbitrary OS images. This takes advantage of that to convert the build over to Ubuntu 16.04 and 18.04 This is using the official Ubuntu provided images and installing extra build deps required, as we previously did with Travis container images. With the switch to Docker though, this can be improved, by building custom Docker images with all the deps pre-installed which will cut down build time. This can be driven from the package lists in libvirt-jenkins-ci repo, to remove the duplication. This work for future improvement though, this just does the minimal conversion to match what we already do, but with newer distro. Signed-off-by: Daniel P.

[libvirt] [Bug] To long backingchain does not work (3 and more...)
by Xen Mann 07 Jun '18

07 Jun '18

Hey there! I'm experiencing a strange behavior with libvirt and backing chains. Getting higher than the first overlay results in a permission denied to the base image and I can't start any machine. # Results while attempting to start machine (after every attemt the whole files from ./houseBackup are restored) Base.img (ok - Win 10 Installation starting) FirstFloor.ovl (ok - Win 10 Installation starting) SecondFloor.ovl (permission denied -> Base.img) => assumed Bug Roof.ovl (permission denied -> Base.img) => assumed Bug The bug is described in detail here together with a minimal example. But maybe I'm still doing something wrong and somebody can give me a heads up =). https://bugzilla.redhat.com/show_bug.cgi?id=1588373 Thx, yours Xensemann!

[libvirt] [PATCH v2] As qemuMonitorJSONIOProcess() will unlock the qemu monitor, there is some extreme situation, eg qemu send message to monitor twice in a short time, where the local viriable 'msg' of qemuMonitorIOProcess() could be a wild point:
by Weilun Zhu 07 Jun '18

07 Jun '18

1. qemuMonitorSend() assign mon->msg to parameter 'msg', which is alse a local variable of its caller qemuMonitorJSONCommandWithFd(), cause eventloop to send message to monitor, then wait condition. 2. qemu send message to monitor for the first time immediately. 3. qemuMonitorIOProcess() is called, then wake up the qemuMonitorSend() thread, but the qemuMonitorSend() thread stuck for a while as cpu pressure or some other reasons,, which means the qemu monitor is still unlocked. 4. qemu send event message to monitor for the second time, such as RTC_CHANGE event 5. qemuMonitorIOProcess() is called, the local viriable 'msg' is assigned to mon->msg. 6. qemuMonitorIOProcess() call qemuMonitorJSONIOProcess() to deal with the qemu event. 7. qemuMonitorJSONIOProcess() unlock the qemu monitor in the macro 'QEMU_MONITOR_CALLBACK', then qemuMonitorSend() thread get the mutex and free the mon->msg, assign mon->msg to NULL. so the local viriable 'msg' of qemuMonitorIOProcess() is a wild pointer now. AFAIK, it is not harmful to call again virCondBroadcast() while msg is a wild pointer, but just in case, we fix it in this patch. --- src/qemu/qemu_monitor.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index 43f1d2f816..4a7013367d 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -454,6 +454,14 @@ qemuMonitorIOProcess(qemuMonitorPtr mon) #if DEBUG_IO VIR_DEBUG("Process done %d used %d", (int)mon->bufferOffset, len); #endif + + /* As the monitor mutex was unlocked in qemuMonitorJSONIOProcess() + * while dealing with qemu event, mon->msg could be changed, + * thus we re-acquire the msg here */ + msg = NULL; + if (mon->msg && mon->msg->txOffset == mon->msg->txLength) { + msg = mon->msg; + if (msg && msg->finished) virCondBroadcast(&mon->notify); return len; -- 2.18.0.rc1

Is it possible to specify a virtio specific attribute via this method? For ex: to say mrg_rxbuf is off we can add the following line to virtio section of the domain xml file. <host mrg_rxbuf='off'/> I think libvirt needs to be extended to to support the new 'standby' attribute via this mechanism. Adding Liane Stump and libvirt to the CC list. Michael, Can we start with getting this patch into Qemu and an update to libvirt to support the 'standby' feature so that this feature can be enabled via some scripts/orchestration layer for now. We could improve this solution by enhancing Qemu to do automatic management of the addition/deletion of the primary device based on feature negotiation as a later patch. > > The patch looks good to me.
