Hi,
Running on:
$ cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)
And:
$ rpm -qa |grep libvirt
libvirt-daemon-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-driver-qemu-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-driver-secret-2.0.0-10.el7_3.5.x86_64
libvirt-client-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-driver-network-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-driver-storage-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-config-nwfilter-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-config-network-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-driver-nodedev-2.0.0-10.el7_3.5.x86_64
libvirt-2.0.0-10.el7_3.5.x86_64
libvirt-python-2.0.0-2.el7.x86_64
libvirt-daemon-driver-nwfilter-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-driver-lxc-2.0.0-10.el7_3.5.x86_64
libvirt-daemon-driver-interface-2.0.0-10.el7_3.5.x86_64
I’m seeing duplicated reboot events when using the python event api. Use is simplified down to the simple test case attached. Running with that results in:
$ sudo ./libvirt_events_single.py
Reboot: Domain i-06945b37(21)
1494958504.72
Reboot: Domain i-06945b37(21)
1494958504.74
This is reproducible 100% of the time by doing /sbin/reboot from within a VM started with qemu-kvm. Any ideas on whats going on?
Let me know if any other information would be useful.
Thanks
Martins

while True:
