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

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. In our environment guest virtual machines periodically 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] Do you have any ideas?... Best regards, Igor.
