abrt 1.0.8 detected a crash. architecture: i686 Attached file: backtrace cmdline: libvirtd --daemon component: libvirt executable: /usr/sbin/libvirtd kernel: 2.6.32.10-90.fc12.i686.PAE package: libvirt-0.7.1-15.fc12 rating: 4 reason: Process /usr/sbin/libvirtd was killed by signal 11 (SIGSEGV) release: Fedora release 12 (Constantine) How to reproduce ----- 1. Create an LXC instance on one host: [root@argon ~]# virsh --connect lxc:/// define /etc/libvirt/lxc/vm1_fedora.xml 2. Test local connection (everything is OK): [root@argon ~]# virsh --connect lxc:/// start vm1_fedora [root@argon ~]# virsh --connect lxc:/// list --all [root@argon ~]# virsh --connect lxc:/// console vm1_fedora 3. Try to access remotely (via ssh) from a different host: [root@neon ~]# virsh --connect lxc+ssh://argon Step 3. crash libvirtd on the original host (argon).

Just found how to make it NOT crash. Simply use: [root@neon ~]# virsh --connect lxc+ssh://argon/ The trailing slash (/) does the trick. Without it the bug is triggered. 1. This is still a bug (IMO). 2. The real culprit is probably the code that calls lxcOpen() -- It is valid for lxcOpen() to fail because of bad URI (altough it would be nice for it to be less picky). However it is not valid for this to crash libvirtd. 3. I just tried to trigger the crash as normal user. The authentication failure blocked it before reaching the buggy code, so it looks like there aren't any security implications yet.
I am also having a similar issue with running GFS & rgmanager polling libvirt for a virsh status. After a couple of weeks uptime I am consistently having this same issue. Even though the vm is still running and up rgmanager requires the libvirt daemon to be restarted and rgmanager resource to be started & stopped to put it back in the correct state. It's a real pain..

Adrian, doesn't sound like your issue is the same as the original report. Can you run 'gdb libvirtd', reproduce the crash, then enter 'thread apply all bt' and open a new bug? Thanks
Also, seems there is already another bug tracking this issue. *** This bug has been marked as a duplicate of bug 554191 ***
