[libvirt] [PATCH] util: fix build without macvtap
by Roman Bogorodskiy
Commit 370608b added new functions:
- virNetDevMacVLanReleaseName,
- virNetDevMacVLanReserveName.
Add stubbed versions of them to fix build without macvtap.

[libvirt] [PATCH] Fix libvirtd free() segfault when migrating guest with deleted open vswitch port
by Jason J. Herne
libvirtd crashes on free()ing portData for an open vswitch port if that port
was deleted. To reproduce:
ovs-vsctl del-port vnet0
virsh migrate --live kvm1 qemu+ssh://dstHost/system
Error message:
libvirtd: *** Error in `/usr/sbin/libvirtd': free(): invalid pointer: 0x000003ff90001e20 ***
The problem is that virCommandRun can return an empty string in the event that
the port being queried does not exist. When this happens then we are
unconditionally overwriting a newline character at position strlen()-1. When
strlen is 0, we overwrite memory that does not belong to the string.
The fix: Only overwrite the newline if the string is not empty.

[libvirt] [PATCH] virnetdevmacvlan: Provide stubs for build without macvtap
by Michal Privoznik
In 370608b4c76f we have introduced two new internal APIs.
However, there are no stubs for build without macvtap. Therefore
build on systems lacking macvtap support (e.g. mingw or freebds)
fails when trying to link.

[libvirt] high outage times for qemu virtio network links during live migration, trying to debug
by Chris Friesen
Hi,
I'm using libvirt (1.2.12) with qemu (2.2.0) in the context of OpenStack.
If I live-migrate a guest with virtio network interfaces, I see a ~1200msec
delay in processing the network packets, and several hundred of them get
dropped. I get the dropped packets, but I'm not sure why the delay is there.
I instrumented qemu and libvirt, and the strange thing is that this delay seems
to happen before qemu actually starts doing any migration-related work. (i.e.
before qmp_migrate() is called)
Looking at my timestamps, the start of the glitch seems to coincide with
libvirtd calling qemuDomainMigratePrepareTunnel3Params(), and the end of the
glitch occurs when the migration is complete and we're up and running on the
destination.
My question is, why doesn't qemu continue processing virtio packets while the
dirty page scanning and memory transfer over the network is proceeding?
Thanks,
Chris

[libvirt] [PATCH] vircgroup: Finish renaming of virCgroupIsolateMount
by Michal Privoznik
In dc576025c360 we renamed virCgroupIsolateMount function to
virCgroupBindMount. However, we forgot about one occurrence in
section of the code which provides stubs for platforms without
support for CGroups like *BSD for instance.

[libvirt] [PATCH] lxc: don't try to hide parent cgroups inside container
by Daniel P. Berrange
On the host when we start a container, it will be
placed in a cgroup path of
/machine.slice/machine-lxc\x2ddemo.scope
under /sys/fs/cgroup/*
Inside the containers' namespace we need to setup
/sys/fs/cgroup mounts, and currently will bind
mount /machine.slice/machine-lxc\x2ddemo.scope on
the host to appear as / in the container.
While this may sound nice, it confuses applications
dealing with cgroups, because /proc/$PID/cgroup
now does not match the directory in /sys/fs/cgroup
This particularly causes problems for systems and
will make it create repeated path components in
the cgroup for apps run in the container eg
/machine.slice/machine-lxc\x2ddemo.scope/machine.slice/machine-lxc\x2ddemo.scope/user.slice/user-0.slice/session-61.scope
This also causes any systemd service that uses
sd-notify to fail to start, because when systemd
receives the notification it won't be able to
identify the corresponding unit it came from.
In particular this break rabbitmq-server startup
Future kernels will provide proper cgroup namespacing
which will handle this problem, but until that time
we should not try to play games with hiding parent
cgroups.

[libvirt] Compiling libvirt on Cygwin
by Maarten Jacobs
Hello,
I have been trying to get libvirt compiled on Cygwin but I have run into a rather perplexing issue.
I am running a 32-bit installation of Cygwin on Windows 10:
CYGWIN_NT-10.0-WOW dell-desktop 2.4.0(0.293/5/3) 2016-01-15 16:14 i686 Cygwin
I have had to "fix" a number of problems in the Makefile that prevented the code from linking properly. I am not sure if the fixes are entirely correct - but as long as the linker was ok I pressed on.
After applying those changes to the Makefile, I ran into the following issue when creating libvirtd.exe:
CCLD libvirtd.exe../src/.libs/libvirt_driver_remote.a(libvirt_net_rpc_la-virnetmessage.o): In function `virNetMessageNew':/home/maart/source/libvirt/src/rpc/virnetmessage.c:39: multiple definition of `virNetMessageNew'/home/maart/source/libvirt/src/.libs/libvirt.dll.a(d002143.o):(.text+0x0): first defined here...collect2: error: ld returned 1 exit statusMakefile:2152: recipe for target 'libvirtd.exe' failedmake[3]: *** [libvirtd.exe] Error 1make[3]: Leaving directory '/cygdrive/c/cygwin64/home/maart/source/libvirt/daemon'Makefile:2050: recipe for target 'all' failedmake[2]: *** [all] Error 2make[2]: Leaving directory '/cygdrive/c/cygwin64/home/maart/source/libvirt/daemon'Makefile:1993: recipe for target 'all-recursive' failedmake[1]: *** [all-recursive] Error 1make[1]: Leaving directory '/cygdrive/c/cygwin64/home/maart/source/libvirt'Makefile:1887: recipe for target 'all' failedmake: *** [all] Error 2
It appears to me that somehow when the executable is linked together, it finds two separate definitions of the virNetMessageNew method, however I cannot figure out how that could be.
If anybody has any suggestions on how to debug this I'd appreciate it.
For clarity: my aim is to get the code to compile first, whether or not it will actually work under Cygwin. I do not believe there should be a specific reason why this code could not be made to compile/link - even if the end result may not work as intended... But I hope to find that out once I successfully create the resulting executables.
Thanks,
Maarten Jacobs

[libvirt] [PATCH] qemu: turn on virtlockd by default
by Daniel P. Berrange
We have had virtlockd available for a long time now but
have always defaulted to the 'nop' lock driver which does
no locking. This gives users an unsafe deployment by
default unless they know to turn on lockd. virtlockd will
auto-activate via systemd when guests launch, so setting
it on by default will only cause upgrade pain for people
on non-systemd distros.

[libvirt] [PATCH v2] qemu: add reporting of vCPU wait time
by Daniel P. Berrange
The VIR_DOMAIN_STATS_VCPU flag to virDomainListGetStats
enables reporting of stats about vCPUs. Currently we
only report the cumulative CPU running time and the
execution state.
This adds reporting of the wait time - time the vCPU
wants to run, but the host schedular has something else
running ahead of it.
The data is reported per-vCPU eg
$ virsh domstats --vcpu demo
Domain: 'demo'
vcpu.current=4
vcpu.maximum=4
vcpu.0.state=1
vcpu.0.time=1420000000
vcpu.0.wait=18403928
vcpu.1.state=1
vcpu.1.time=130000000
vcpu.1.wait=10612111
vcpu.2.state=1
vcpu.2.time=110000000
vcpu.2.wait=12759501
vcpu.3.state=1
vcpu.3.time=90000000
vcpu.3.wait=21825087
In implementing this I notice our reporting of CPU execute
time has very poor granularity, since we are getting it
from /proc/$PID/stat. As a future enhancement we should
prefer to get CPU execute time from /proc/$PID/schedstat
or /proc/$PID/sched (if either exist on the running kernel)
