[libvirt] Qemu-Libgfapi: periodical shutdown of virtual machines.

[Igor Yakovlev]

Hello,

Would you so kind to help me with my problem concerning libgfapi.

My host operating system is Ubuntu 14.04 LTS, version of glusterfs is 
3.6.2, and version of qemu is 2.0.0. We use libfgapi library to connect to glusterfs.

In our environment virtual machines sometimes go to power-off 
state 'Powered Off'(Shutdown) with ERROR in /var/log/syslog like:

kernel: [5346607.988173] qemu-system-x86[29564]: segfault at 128 ip
00007f930a90b48c sp 00007f931296fd70 error 4 in
qemu-system-x86_64[7f930a57f000+4b1000]

Please help me to understand possible reasons of the qemu-system segfault.
Maybe glusterfs tuning is required or tuning of libvirt.

Do you have any ideas?...

Best regards,
Igor.
