Hi Guys, I've been having some issues this week with my oVirt 4.1 install on CentOS 7... It was previously working great but I made a couple of alterations(which I've mostly backed out now) and I ran a yum update followed by a reboot, however. after it came back up I couldn't start any virtual machines... The oVirt web interface reports : VDSM Local command SpmStatusVDS failed: Heartbeat exceeded VDSM Local command GetStatsVDS failed: Heartbeat exceeded VM My_Workstation is down with error. Exit message: Failed to find the libvirt domain. Plus some other errors so I checked my "dmesg" output and libvirtd seems to segfault : [70835.914607] libvirtd[10091]: segfault at 0 ip 00007f681c7e7721 sp 00007f680c7d2740 error 4 in libvirt.so.0.2000.0[7f681c73a000+353000] Next I checked logs but I couldn't find anything that seemed relevant to me, I mean I see lots of oVirt complaining but that makes sense if libvirtd segfaults right? So last ditch effort was try and use strace and hope with my limited knowlege I spot something uselful but I didn't so I've attahced the strace output to this email in the hope someone else might.
