Does anything suspecious show up on libvirtd.log?
I heard a report about a libvirt segmentation fault on centos7 - could this be it, too? Does `ps -o stime `pgrep libvirtd`` match with reported libvirt "internal error"?
Would you provide the precise version of libvirt and vdsm?
Confirmed. I'm aware of these bugs in particular, which could be related to a fair amount of mysterious libvirtd crashes: https://bugzilla.redhat.com/show_bug.cgi?id=1162208 https://bugzilla.redhat.com/show_bug.cgi?id=1171124 https://bugzilla.redhat.com/show_bug.cgi?id=1141159 It seems *more frequent* when migrations are involved, but as last bug tells us, it may happen on other cases as well. -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani
