Comment 7 yanbing du 2013-03-18 10:42:58 UTC
Reproduce this bug with libvirt-0.10.2-18.el6.x86_64.
Following the steps from
http://www.redhat.com/archives/libvir-list/2012-December/msg01365.html
About 15 mins later, libvirtd crashed:

# virsh list
error: Failed to reconnect to the hypervisor
error: no valid connection
error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Connection refused

# service libvirtd status
libvirtd dead but pid file exists

libvirtd.log:

2013-03-18 10:14:34.707+0000: 3874: error : qemuMonitorIO:613 : internal error End of file from monitor
Caught Segmentation violation dumping internal log buffer:


    ====== start of log =====
<snip/>
     ====== end of log =====

Then upgrade libvirt to libvirt-0.10.2-18.el6_4.1.x86_64, and test again, about 20 mins later, libvirtd still running, So this bug can move to VERIFIED.
