[libvirt] Libvirtd and OSX... with QEMU

Heyas, Interestingly on OSX, starting libvirtd (1.3.1) indicates it can see the installed QEMU. However, it crashes out shortly afterwards with a weird error: 2016-01-17 22:02:17.159+0000: 18446744073709551615: error : virEventPollRunOnce:648 : Unable to poll on file handles: Bad file descriptor Does anyone know what that might be about, and/or how to capture more meaningful info? :) Regards and best wishes, Justin Clift
