I think this patch should fix your problem:

https://www.redhat.com/archives/libvir-list/2012-December/msg00935.html

If so, can you please test and confirm that since you already have everything set up.

Michal

I have applied this patch, on top of stable v1.0.1. I am going have my test running over the weekend, and will report back if I get another SIGSEGV as I saw before.

However so far, I have ran the same test as I noted in my previous posting, and after maybe 20 minutes this time I got another halt in my GDB session, though this time it is a SIGPIPE. Here is the output:

Program received signal SIGPIPE, Broken pipe.
