[libvirt] Libvirt 0.10.0-rc1 segfaults when daemon run as root



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:

Segmentation fault/

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:

2012-08-23 19:02:15.145+0000: 27483: info : libvirt version: 0.10.0
2012-08-23 19:02:15.145+0000: 27483: error : virDriverLoadModule:78 : failed to load module /usr/local/lib/libvirt/connection-driver/libvirt_driver_qemu.so /usr/local/lib/libvirt/connection-driver/libvirt_driver_qemu.so: undefined symbol: virSecurityManagerGetProcessLabel
2012-08-23 19:02:15.145+0000: 27483: error : virDriverLoadModule:78 : failed to load module /usr/local/lib/libvirt/connection-driver/libvirt_driver_lxc.so /usr/local/lib/libvirt/connection-driver/libvirt_driver_lxc.so: undefined symbol: virSecurityManagerGetProcessLabel

Any ideas why this is happening? I am on Ubuntu 10.04 running libvirt 0.10.0 with qemu-kvm 1.1

Thanks,
Shawn
