Hi, I am starting a libvritd process when booting up an embedded networking system via python, like so: subprocess.Popen(["libvirtd","-d"],stdout=subprocess.PIPE,stderr=subprocess.PIPE)
This runs and works fine for version 1.2.20. However after I upgraded to 2.3.0 I started noticing an intermittent bug. Sometimes my CLI will hang when libvirtd is starting (most of the time it starts fine).
I ssh'd in and had a look around. libvirtd had a second process entry:
[root@trx-r2 log]# ps ax | grep libvirt
826 ? Sl 0:00 libvirtd -d
843 ? S 0:00 libvirtd -d
869 pts/0 S+ 0:00 grep libvirt
Using strace I could see the second entry was blocking (FUTEX). Kill libvirtd processes and the boot continues as normal. I updated libvirt to the latest version and this still happens. To confirm I downgraded to 1.2.20 again and everything works smoothly. Any idea of what may have changed to cause this, pointers for me as to where to have a look?
Thanks,
