But when I try to do on nightwish : $ wget www.qemu.org The opeth QEMU makes a segfault : "11586 Segmentation Fault" This phenomenon is not always present... If the Segfault does not appear, nightwish cannot enable a connection with internet :( Thanks Vince To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/938945/+subscriptions
