Hi All,
Refering to the link below, I got to know that previous versions of
Libvirtd had this issue.
https://www.redhat.com/archives/libvirt-users/2012-August/msg00104.html
We are using libvirt-0.10.0 but we are facing the same issue.
Procedure to reproduce :
1. Login to some domain name say CLA-0 using virsh.
(i) # virsh list --all
Id Name State
----------------------------------------------------
4 CLA-0 running
(ii) # virsh console 4
Connected to domain CLA-0
Escape character is ^]
2. Whenever we exit from the above CLA-0 domain by pressing ctrl-]
We are getting the Segmentation fault, however core is not generated but we
have debugged it through gdb
Program received signal SIGSEGV, Segmentation fault.

After this point libvirtd is dead.
# service libvirtd status
libvirtd dead but pid file exists
>From the mail conversation between you and Andrey we came to know that
patch has been provided for this problem.
Could you please share us the fix.
Thanking you in anticipation.
Thanks and Regards,
