Since upgrading to sys-libs/glibc-2.10.1-r1, I have been unable to start libvirtd. It segfaults in virStateInitialize. Disabling udev support in libvirt fixes this, so I suspect it is a problem with how libvirtd calls udev. Reproducible: Always Steps to Reproduce: 1. /etc/init.d/libvirtd start Actual Results: # rm /var/run/libvirtd.pid ; gdb libvirtd warning: Can not parse XML syscalls information; XML support was disabled at compile time.

have you tried to recompile udev and libvirtd?
I was pretty sure I had, but maybe I didn't do it in the right order. Things are working with USE=udev now.
