I've seen bug #301217. Rebuilding libvirt with USE=-udev fixes the problem. And no, rebuilding udev does not help. If libvirt is built with USE=udev, it segfaults at startup, even if I previously rebuild udev.
libvirtd-0.7.6 is somewhat better in that using USE=udev doen't segfaults, but still it doesn't start. # libvirtd 09:59:19.162: error : udevSetupSystemDev:1477 : Failed to get udev device for syspath '/sys/devices/virtual/dmi/id' or '/sys/class/dmi/id' 09:59:19.162: error : virStateInitialize:890 : Initialization of udev state driver failed 09:59:19.162: warning : qemudStartup:1099 : Unable to create cgroup for driver: No such device or address 09:59:19.187: error : main:3154 : Driver state initialization failed 09:59:19.187: warning : qemudDispatchSignalEvent:385 : Shutting down on signal 3 # strace libvirtd ... fstat(11, {st_mode=S_IFREG|0600, st_size=1242, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f4273931000 read(11, "<domain type='kvm'>\n <name>CMED"..., 16384) = 1242 read(11, "", 12288) = 0 lseek(11, 0, SEEK_CUR) = 1242 lseek(11, 0, SEEK_SET) = 0 read(11, "<domain type='kvm'>\n <name>CMED"..., 4096) = 1242 read(11, "", 4096) = 0 read(11, "", 4096) = 0 close(11) = 0 munmap(0x7f4273931000, 4096) = 0 getdents(10, /* 0 entries */, 32768) = 0 close(10) = 0 getuid() = 0 geteuid() = 0 open("/etc/passwd", O_RDONLY|O_CLOEXEC) = 10 lseek(10, 0, SEEK_CUR) = 0 fstat(10, {st_mode=S_IFREG|0644, st_size=1443, ...}) = 0 mmap(NULL, 1443, PROT_READ, MAP_SHARED, 10, 0) = 0x7f4273931000 lseek(10, 1443, SEEK_SET) = 1443 munmap(0x7f4273931000, 1443) = 0 close(10) = 0 uname({sys="Linux", node="rowlf", ...}) = 0 inotify_init() = 10 stat("/root/.uml", {st_mode=S_IFDIR|0755, st_size=48, ...}) = 0 inotify_add_watch(10, "/root/.uml", IN_MODIFY|IN_CREATE|IN_DELETE) = 1 write(4, "\0", 1) = 1 futex(0x69e580, FUTEX_WAKE_PRIVATE, 1) = 1 open("/etc/libvirt/uml", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = -1 ENOENT (No such file or directory) getuid() = 0 write(2, "09:59:30.223: error : main:3154 "..., 69) = 69 kill(4122, SIGQUIT) = 0 --- SIGQUIT (Quit) @ 0 (0) --- write(6, "\3\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\32\20\0\0\0\0\0\0\"\v\222\0\0\0\0\0"..., 128) = 128 rt_sigreturn(0) = 0 futex(0x907ed0, FUTEX_WAKE_PRIVATE, 1) = 1 munmap(0x7f426d261000, 8392704) = 0 close(5) = 0 close(6) = 0 close(8) = 0 close(7) = 0 close(9) = 0 close(10) = 0 unlink("/var/run/libvirtd.pid") = 0 exit_group(1) = ?

Can you follow the backtrace guide and provide a backtrace of libvirtd segfaulting, the guide is available here: http://www.gentoo.org/proj/en/qa/backtraces.xml
Also, what does the following command output: $ udevadm info -q property --path /sys/devices/virtual/dmi/id
(In reply to comment #5) > Also, what does the following command output: > > $ udevadm info -q property --path /sys/devices/virtual/dmi/id # udevadm info -q property --path /sys/devices/virtual/dmi/id device path not found For the backtrace, sorry but I won't be able to rebuild it with debugging enabled until the end of next week. Will provide the backtrace then. Thank you.

Ok. Just to give you some feedback. There was a definite bug in the parser in 0.7.5, which is now fixed in 0.7.6 (mostly, I'm still seeing some issues). However, 0.7.6 considers missing dmi data as fatal. The fix is currently banging its way around the ML and once upstream commits it to their git master, I'll pull the patch in and that should fix the issue.
Thanks!
*** Bug 316063 has been marked as a duplicate of this bug. ***
This is fixed for sure in the 0.8.1 versions in the tree.
So this means that it will now be possible to build with USE=udev, is my understanding correct?
(In reply to comment #13) > So this means that it will now be possible to build with USE=udev, is my > understanding correct? > Yep. You should be set now.
