Bug 301217 – app-emulation/libvirt-0.7.5 segfaults with sys-libs/glibc-2.10.1-r1

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Daniel Westermann-Clark 2010-01-16 19:19:52 UTC]

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

have you tried to recompile udev and libvirtd?

[Comment 2 Daniel Westermann-Clark 2010-01-17 15:07:51 UTC]

I was pretty sure I had, but maybe I didn't do it in the right order. Things are working with USE=udev now.
