Hi all,
For some reason when I run "libvirtd -d" as root it seems to not
start. I investigate by running "libvirtd -v" as root and I get a
segfault. Here is the output:

However, when I run "libvirtd -d" as me, it does not segfault and
continues running. However I cannot connect to the libvirt-sock
because it gets created at "$HOME/.cache/libvirt/libvirt-sock" but
virsh looks for it at "/usr/local/var/run/libvirt-sock".
Here is what I get when I run "libvirtd -v" as me:

Any ideas why this is happening? I am on Ubuntu 10.04 running libvirt
0.10.0 with qemu-kvm 1.1
Thanks,
Shawn
Sorry, I couldn't reproduce this problem on my machine,
This problem could be reproduced 100 percent.
Could you use gdb for grabbing backtrace?
